Darlena Allen 

Clinical Director 


To be human is to feel stress, to feel overwhelmed, and at times, to even feel alone. I welcome the opportunity to hear your experience, through providing my undivided attention, and support. Your thoughts, feelings, and needs are not only worthy of being heard, they deserve respect and regard. It is my goal to create an environment in which you feel safe, and empowered to share your unique story. Together we will not only set your goals, but identify, and work towards your preferred reality.


My experience includes working with children with behavioral issues at home/school, working with families on co-parenting issues, working with children of separation/divorce, working with foster children/families, working with blended families, and working with Depression and Trauma.  Also, assisting therapists navigate the unique challenges of the profession.  The strength based theoretical approaches which inform my work includes: Attachment-Based Therapy, Solution-Focused Therapy, Narrative Therapy and Reflective Supervision. It is my belief that, not only are we individually, equipped to solve the human condition, but that, in addition, we are the authors of our own story. If you will allow me to utilize my journey to witness your story as you write and re-write your Narrative, you will learn the following: 
“You are braver than you believe, stronger than you seem, and smarter than you think” - A.A. Milne, creator of Winnie-The-Pooh


Robyn Norris 

Clinical Supervisor


My passion lies in helping individuals from a relational perspective and instilling hope
and assurance of ones individual journey in order to help live a life that is of fulfillment. I
believe we all have a story and the right to be heard and seen and that is what I look to offer you within our therapeutic relationship. I believe the therapist-client relationship is integral to healing and as such, it should feel collaborative and free from judgement. 


I have extensive experience working with children and adolescents, alongside their
families. I am a firm believer that in order to help the child, we must also examine the family. I have provided such therapeutic services to children and families in community mental health clinics, school-based settings and residential treatment facilities. As such, I have extended training in trauma focused cognitive behavioral therapy as well as knowledge and training within the 0-5 population. I have experience treating a wide array of issues such as depression, anxiety, ADHD, attachment concerns, trauma, abuse, grief and loss, change of life issues, divorce, adoption, and relational disorders.

In my professional capacity I have also had experience providing clinical supervision and oversight to pre-licensed and licensed therapist. I take joy in working alongside clinicians as they develop and hone their professional skills and knowledge. I believe that as a clinician or “healer” it is important to be reflective in one’s process in order to provide the emotional space needed for those that we serve.

I work from an eclectic lens, often incorporating cognitive behavioral therapies, client-centered approaches, solution-focused, family systems work and narrative therapy. I am comfortable working with individuals of all sexual orientations and genders. As a clinician, I strive for cultural humility and understanding of ones own individual cultural experience. Most importantly, I look forward to working alongside you to assist in your journey of healing.

Clinical Supervisor

LMFT 117308

I am comfortable supporting clients with a wide range of concerns including depression, anxiety, ADHD, relationship issues, parenting problems, career challenges, self-esteem, and issues of grief and loss. I have helped people navigate the complex aftermath that results from physical trauma or emotional abuse.

My counseling style is warm and interactive. I believe in treating everyone with respect, being sensitive, and meeting each client in the space that they are in. My counseling approach pulls from several theories, but I primarily use Cognitive Behavioral Therapy, Solution Focused, and Client Centered Therapies. 

Here's what you can expect in a session with me: I will tailor our dialog and develop a treatment plan to meet your unique and specific needs and goals. I like to provide feedback, share suggestions, and encourage home practice from our previous sessions, so you can see the interventions used in action.  


Dr. Natasha Kordus

I work with children, adolescents, and adults. My approach to therapy is a bit eclectic in that I have specialized training in Cognitive Behavioral Therapy, but I also include early childhood considerations, feminist thought, and multi-cultural perspectives in my interventions. I believe in working closely with my clients as a team on identifying goals and moving forward towards desired changes. I specialize in trauma, depression, anxiety, chronic illness, grief and loss, adjustment difficulties, as well as diagnostic clarification of ADHD, Autism, or psychotic and mood disorders. As a multicultural, Hispanic woman, I love working with clients from diverse backgrounds and, in particular, specialize in working with members of the Deaf / Hard of Hearing and LGBTQ communities. I am fluent in ASL.

Elizabeth Dupray

Marriage and Family Therapist


I am a licensed Marriage and Family therapist who began my educational journey later in life. My life's experiences led me to seek a career more meaningful in helping others. 

Prior to my education in counseling I worked for many years in the grocery business as a retail clerk, getting to know all the customers who came through my lane. I believe that job was a great training ground for my current career as everyone from all walks of life goes to the grocery store. My keen observation of each person and family dynamics was educational in itself. 

My years of internship and counseling have been meaningful when clients have made progress and I get to be a part of their journey. The populations I have the most experience in are clients struggling with anxiety, depression, domestic violence, strained marriages, and relationships. I have helped women stuck in the cycle of abuse and codependency and understanding the pain from my own life's experiences. I have worked with families and individuals struggling with family members addicted to different substances.

Dr. Manijeh Badiee.jpeg

I have done therapy for over ten years. I specialize in clients who are racial/ethnic minorities, queer, transgender, and/or polyamorous. I can provide letters for transgender individuals who pursue medical transition. I have worked with a variety of presenting issues such as depression, anxiety, ADHD, and trauma.

I am a relational-cultural therapist, which means that I view relationships as central to our growth, honor my client's cultural identities, and explore how "isms" (e.g., racism, sexism, etc.) impact my clients. I view therapy as a collaboration in which we work together to address your concerns as well as help you live a life of meaning.

Dr. Tanika Gayle 

Clinical Psychologist


The core of my work is to help people operate from the best in themselves as an individual and in relationship with others. My work helps individuals develop a state of balance by increasing one true, solid sense of self and the ability to take care of self while working through difficulties that life throws at you. Key tools in accomplishing this are by helping individuals self confront and self validate and stay true to ones' integrity. I work with individuals dealing with everyday life stressors, individuals discovering their sense of identity, and various discomforts such as depression, anxiety, relationship issues, and family issues. I have a special interest in treating individuals, families, couples, and intimacy issues which includes sex therapy.

In addition to providing therapy, being the owner/clinical director of Collaborative Psychology Group, I currently am the program manager and primary supervisor for Family Support Services at the Inland Empire Ronald McDonald House. It is a practicum training site for marriage and family therapist, social work and psychology doctorate students. In addition I also have a practicum training program at Collaborative Psychology Group for Loma Linda University master and doctoral students.

People face tremendous stressors, managing life responsibilities, and relationships. Adversity from childhood experiences, unfulfilled expectations, negative family influences leading to despair breaks relationships and families apart. Addressing origins of pain, acknowledging the present and providing strategic tools helps rebuild, leading to better moments now and ahead. As an empathetic licensed marriage and family therapist, LMFT 107822, Vivian enjoys connecting with clients to explore their unique journey by providing a non-judgmental, safe, welcoming space to grow, to heal, to embrace, to discard. Vivian has life experience with an ex-addict community for over 40 years; gaining professional mental health status as of 2012.  Vivian provides counseling to individuals, couples and families dealing with relationship issues, especially those struggling with addictions and anger.  

   As an EMDR (Eye Movement Desensitization and Reprocessing) Therapist, Vivian uses this model for people to heal from emotional distress resulting from disturbing life experiences.  EMDR therapy quickens the healing process. EMDR therapy shows that the mind can, in fact, heal from psychological trauma much as the body recovers from physical trauma.  Using the eight stage detailed protocols and procedures learned in EMDR therapy training sessions, Vivian helps clients activate their natural healing processes.

   Having first-hand experience of living abroad with her family raising five children (Adult Third Culture Kids); Vivian understands the unique challenges expatriate families face while moving and living abroad. Not only has Vivian experienced the process of culture shock, and cultural adaptation, she has therapeutic skills to help you and your family transition to/from life abroad, particularly the reverse struggle of repatriation. Whether you are facing immigration issues, migration, or repatriation, let’s talk!


My experience has included working with children, adolescents, young adults, and families in public schools and community mental health facilities. In addition, I have experience working with suicidal adolescents in an intensive outpatient program and providing support to families of children with medical illnesses. My training has allowed me to gain experience working with a variety of conditions including depression, anxiety, trauma, self-harm, impulse and control issues, behavior and conduct problems, relational concerns, and adjustment difficulties.

Angelica Thomas

Psych Assistant

 I am a doctoral candidate at The Chicago School of Professional Psychology. I received my Master’s degree in Counseling Psychology from National University. My experience includes working in community mental health, working with individuals and couples. I have worked with a diverse population of clients of all ages. I utilize an integrative approach combining cognitive-behavioral, psychodynamic, mindfulness, and humanistic modalities. I believe the therapeutic process guides clients to increased self-awareness and decreased symptoms. Additionally, I am EMDR trained (Eye Movement Desensitization and Reprocessing) and a Certified Rape Crisis Counselor.  


My intention is to help patients heal their relationships and understand trauma's psychological and physical impact. The core of my work is to help patients gain self-insight and awareness, operate from the best in themselves, and improve their relationships with others. I believe the therapeutic relationship is essential to the treatment. I strive to honor my patient’s identities and assist them in exploring intersectionality.


Dr. Jaclyn Cascio

Psych Assistant

I am an advocate for meeting people where they are and moving them forward by helping them set goals for their lives and finding a path to achieve those goals. I lean toward motivational interviewing, cognitive and cognitive-behavioral therapies, and psychoeducational techniques, with the aim of helping others gain self-awareness and learn skills needed to support themselves and continue growth long-term. However, I take an overall person-centered, collaborative, and eclectic approach to working with clients, which means I work closely with each person to create a space of safety and growth together, and then pull from a variety of methods and techniques to find the right tools for each individual to make progress. My experience has primarily been focused on stress management, life transitions, self-esteem and self-efficacy, communication, and mind-body wellness, typically with individuals coping with anxiety, depression, and complex relationship and family issues. As an Army veteran myself, I am especially passionate about helping the military population. Also being a returned Peace Corps volunteer (Rwanda) and having traveled to over a dozen other countries, I have a strong affinity for a multicultural perspective in all my work. I've had experience assisting under-represented and under-served populations through government programs and want to continue to serve such groups who have additional systemic and external barriers to wellness.


I graduated from California Southern University with my PsyD in Clinical Psychology. I received my MS in General Psychology from Grand Canyon University and my BA in Psychology from George Fox University. I continue my learning journey with Collaborative Psychology Group as a psychological assistant, moving toward being eventually licensed as a clinical psychologist.

Morgan Moinian



I am an Associate Marriage and Family Therapist (AMFT) as well as an Associate Professional Clinical Counselor (APCC). I received a Master’s degree from California Baptist University, where I studied Professional Clinical Counseling and Counseling Psychology. Previous studies have allowed me to obtain an additional degree in
Human Development, which informs my approach with developmentally appropriate practices. I have worked with individuals experiencing anxiety, grief and loss, ADHD, depression, and anger management. Additionally, my experiences have allowed me to counsel adolescents and families of Riverside Unified and San Bernardino schools.
I utilize various therapeutic approaches, including cognitive behavioral therapy CBT), person-centered therapy, and mindfulness-based interventions. Among other aspects of therapy, I am passionate about working alongside individuals, families, and couples to 1) strengthen relationships, 2) improve communication skills, 3)
manage daily stress, 4) alleviate the symptoms of negative feelings, 5) improve self-esteem, 6) manage negative emotions, and 7) facilitate problem solving and conflict resolution. Above all, I strive to offer a warm and compassionate space where clients can feel safe and comfortable to be themselves.

My name is Tyron, I am an Associate Professional Clinical Counselor who graduated with a Master of Science from Cal State San Bernardino. I have a background working with children and adults, but I have primarily worked with adults in the mental health field. My history of work has been with populations of individuals that have dealt with trauma, substance abuse/use,
bipolar, schizophrenia, and individuals on the spectrum. Most of my experience has been
working with the clinical population in the mental health field. I have worked with the clinical population for about 5 years, and I have learned many ways of approaching and connecting with people from a wide range of different backgrounds.


My therapeutical approach to therapy is rooted in Narrative therapy which aims to separate individuals from their problems. In this therapy approach, I intend on supporting individuals in reframing a new life narrative for themselves. In establishing this new narrative, I hope to develop a relationship with my clients where I can help support to empower individuals in meeting their goals and sustaining a healthier lifestyle. I do my best to facilitate an environment that allows for open expression of emotions and thoughts but also develops a space for me and individuals to build a strong relationship to being completely vulnerable and transparent with
each other. Most of all, it is my goals to support and improve the quality of life in individuals that come to see me.

Any moment of life could be a great time to seek help. Maybe you have gone through some unexpected changes in your life? Or maybe you are feeling lonely, anxious, tearful, or down about yourself and your current life circumstances. Or maybe you are unsure how you are feeling but are interested in growing and feeling more empowered in your life. Taking that first step and seeking a therapist can be challenging and daunting at first, and I want to help you in your journey of self-healing and having a safe place to do so.


I am a therapist who works with all ages and offers Individual, Couples, and Families. My therapeutic approach is eclectic and holistic. I have experience working with anxiety, depression, sadness, grief and loss and stress.


It is a gift to be able to work with others. I love helping all souls on their own personal journeys. And I am here to help create something that may sound uncomfortable, such as therapy, feel more comfortable. This is the time to go on your path of healing and self-discovery. And I would love to be a compassionate outside perspective for you and help reach any personal goals you may have.

I am an Associate Marriage and Family Therapist (AMFT131599) with a Masters in Counseling from California State University, Fullerton. I have experience working as a counselor at a community clinic and kindergarten through eighth grade school setting. Previous experience includes supporting my local unhoused population and youth in a community shelter.

My goal is to create a space where clients feel safe and supported enough to share their stories and struggles and learn to live their most fulfilled lives.

AMFT 122046

Hello, I have been working in the field of mental health since 2019 while earning my Master’s Degree in Counseling Psychology from California Baptist University. During this time, I have had the privilege of supporting adults and adolescents in various settings including in-patient treatment, an outpatient community mental health clinic, and school based counseling. I draw from an array of theoretical orientations based on my client’s unique needs including: Cognitive Behavioral Therapy (CBT), Acceptance and Commitment Therapy (ACT), Dialectic Behavioral Therapy (DBT), Attachment Theory, Narrative Therapy, Systems Theory, Solution Focused Therapy, and Mindfulness Based Cognitive Therapy (MBCT). My therapeutic style is strongly rooted in mindfulness based interventions. I have experienced mindfulness based interventions to be extremely helpful in reducing worry and rumination which so often accompany anxiety and depression. I have worked supporting individuals who are experiencing or have experienced: anxiety, depression, codependency, Intimate Partner Violence, substance use disorders, process addictions, trauma, grief and loss, housing insecurity, current or previously involvement with the justice system, current or previous involvement with the foster care system. My clinical experience has included working with culturally diverse populations from various ethnic backgrounds, religious backgrounds, gender expressions, and sexual orientations. I believe that a safe therapeutic environment is the most crucial element in opening up space to facilitate healing for people. I strive to create a therapeutic environment which is supportive, collaborative, and respects that each individual has a unique lived experience and inherent value.

Pain and stress are inextricable parts of our human existence. I strive to support clients in
developing compassionate responses to their suffering. I firmly believe that all behavior and
emotions are expressions of universal human needs trying to be met. Sometimes the ways we have gotten these needs met in the past have been useful or necessary; but they may no longer serve us. I want to help people become more attuned to what their behaviors, relationships, and emotions can tell them about the needs they have and explore ways they might get these fundamental human needs met in a fashion that will be most fulfilling, affirming, and positive for them.

Associate Marriage and Family Therapist


Hi, I am Amanda. I have recently received my Master’s degree in Clinical Psychology and Marriage and Family Therapy from Azusa Pacific University. I have had the privilege of working with clients of all ages and backgrounds. Most of my clinical experience has been working with those aiming to address their difficulties with anxiety, depression, and relationships. Throughout my work, I have loved focusing on developing self-identity, coping skills, and communication with individuals. As a first-generation American, I know there are unique challenges that come with that, which has led me to love working with others who experience cultural challenges. Therapeutically, I am very eclectic and draw skills from Cognitive Behavioral, Narrative, and Person-Centered therapies. I believe that therapy is a unique space where you can be yourself, be heard, and be understood. My aim is to create a space that allows you to do so. I am truly passionate about coming alongside you on your mental health journey.

I am an Associate Marriage and Family Therapist with a master's in psychology from Cal Poly Pomona. During my time in graduate school, I had the privilege of working with individuals, couples, and families at Ronald McDonald House Charities. I also had experience running therapeutic groups with children and a support group for adults. I value identity work which includes cultural sensitivity and respect for different backgrounds, cultures, and beliefs. My style is person-centered, I strive to create an environment that is safe, authentic, and caring. Life comes with many seasons, we experience grief, loss, anxiety, depression, transitional periods, and relational issues, My goal is to provide tools for better coping while getting to the root of the issue. I Also challenge people to confront the parts of themselves that have been left unseen or neglected. Operating from a solid sense of self creates the space to relate more intentionally, learn to self-regulate, and better mange the difficult seasons of life. I love what i do, and it would be an honor to work alongside you during your healing journey.
