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

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.

As a registered Associate Marriage & Family Therapist (AMFT#112456) and Associate Professional Clinical Counselor (APCC#6161), I am an RN, with 14 years of Bariatric Medicine experience, I am passionate about helping others understand how emotional and physical health are woven together, each affecting the other in powerful ways. Many of my patients shared their stories of post-op weight regain, new addictions, history of childhood trauma, and the return of sabotaging behaviors. Realizing the great need for effective psychological services, I felt called to become a therapist. The desire to offer a more holistic approach for those who struggle with obesity motivated me to complete a Master’s degree in Counseling
from La Sierra University in Riverside CA.

I have provided counseling for children, teens, adults, couples and families in Palm Springs through Marsell Consulting, where I worked with individuals, couples and families as we as taught a 16-week course on Anger Management. I was honored to play a small role in providing individual and group counseling services for many of Riverside’s homeless population through Path of Life Ministries.
Together we will explore any psychological roadblocks that are getting in the way of you feeling your best. I use evidenced-based counseling modalities such as Cognitive Behavioral Therapy (CBT), Dialectical Behavioral Therapy (DBT), Mindfulness Techniques, Emotional Focused and Compassion Therapies to create a personalized treatment plan customized for your specific needs.

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. I spent my time working with youth helping them process depression, anxiety, phase of life changes, family conflicts, and behavioral changes. I have worked with a wide range of ages as well as people of different ethnicities, cultures, and sexualities. I feel acknowledging these differences promotes growth and honors the client as unique individuals. I tailor my approach to the individual as the experts of their own lives who need support. 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. I use skills from Person-Centered, DBT, CBT, and ACT modalities as well as active listening and psychoeducation on coping skills during sessions to address clients concerns.

Tyron Jackson

Associate Professional Clinical Counselor


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.
