Crystal Folk

Clinical Supervisor

Marriage and Family Therapist

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.  


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.

Kathryn Dietz

Associate Marriage and Family Therapist AMFT131599

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.

Amanda Khalil

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.

My goal is to create a safe space for my clients to feel comfortable to process and express their feelings. I have helped treat people who are dealing with Depression, Anxiety, Social Anxiety, Bereavement, relationship problems, and PTSD. My therapeutic modalities include CBT, TFCBT, SFBT, and Psychodynamic Therapy. I also utilize the Strengths-Based perspective and Motivational Interviewing.

My therapeutic style is calm, understanding, and supportive. I am here to support my clients by providing active listening and space to process your problems. I will help teach them the tools to help devise solutions to problems, help reframe negative thinking patterns, and how to utilize coping mechanisms.

I let my clients know that your session is your session so whatever you need to talk about this is your space. We will devise goals together by creating a treatment plan, so that we can work on those each session, but I think it’s important to focus on the current or new stressors that clients are experiencing as well. I enjoy working with children and Teens and will incorporate therapeutic games or Art to make therapy more fun! “The
meaning of life is to find your gift. The purpose of life is to give it away.” -Pablo Picasso

Any moment of life could be a great time to seek help. Maybe you have gone through some unexpected changes in your life?

Andrea Raquel Solis

Associate Marriage and Family Therapist

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.
