Beth Christensen, LMFT


I have worked as a psychotherapist since 2005 in both agency and private practice settings. I did my undergraduate work at UC Berkeley and my graduate work at St. Mary’s College in Moraga. I am trained in Mindfulness Based Self Compassion (MBSC), Acceptance Commitment Therapy (ACT), Dialectical Behavior Therapy (DBT), and DBT with Prolonged Exposure. I offer a full DBT program with consists of individual therapy, skills groups, phone coaching, and being part of a consultation team. My practice is in Danville, CA.

I am dedicated to providing quality therapy for individuals; couples, whether or not married; families of all types; and groups to cure or relieve mental, emotional, and relational concerns of all kinds. I consider myself to be a lifetime learner and am passionate about continuing to expose myself to new and innovative psychological theories. It is this dedication to quality which ensures that each client is treated with, not only compassion and respect but with creativity and efficiency. Therapy should not be a lifetime experience but rather a short journey between the reality you currently experience and the life you’ve always envisioned for yourself. I am competent to work with a multitude of disorders and specialize in issues related to relationship strengthening and personal growth.

Taking the first step to seek help can be a difficult decision. But the progress and transformation that can result from working towards a better quality of life are invaluable. As a licensed psychotherapist, I specialize in providing evidence-based treatments for a variety of concerns, including anxiety, depression, relationships, life stressors, trauma, and addiction. My approach integrates Cognitive Behavioral Therapy, Dialectical Behavior Therapy, Mindfulness, and EMDR, depending on each client's unique needs.

With over a decade of experience working in both agency and private practice settings, I have developed a deep passion for helping individuals overcome life challenges to improve their overall well-being. My goal is to empower my clients to discover and develop the tools to effectively manage and treat various diagnoses, such as mood disorders, anxiety, trauma, and adjustment disorders.

I believe each person possesses the innate ability to solve problems and heal from past trauma when given the right kind of setting, professional guidance, and unconditional support. I focus on doing what works for each individual to reduce suffering and build a life worth living. I also believe that skills learned in DBT are an integral part of the healing process. That is why I have chosen to focus my practice on providing the most comprehensive, compassionate, and adherent style of DBT available.

I am trained in Dialectical Behavior Therapy (DBT), Acceptance Commitment Therapy (ACT), Integrative Restoration for Trauma (iRest), Trauma Education, and Exposure Therapy. I am also a certified Yoga Teacher (RYT200) specializing in Yin Yoga, Yoga Nidra, and Mindfulness Meditation. In my private practice, located in Danville, CA, I offer a complete DBT program of individual therapy, skills groups, phone coaching, and consultation team meetings.

Currently, I work with children, adolescents, and adults who struggle with a wide range of issues, including anxiety, depression, trauma, gender issues, personality disorders, bipolar disorder, emotional regulation, and family or interpersonal communication challenges. I provide individual therapy and co-facilitate weekly DBT Adult and Multi-Family Skills Groups.

I hold a Master of Arts in Counseling Psychology from The Wright Institute, Berkeley. Before joining Mount Diablo Psychological Services, I worked for the Alameda Health System at Fairmont Hospital, San Leandro. At Fairmont, I treated patients with a wide range of severe mental health conditions, including schizophrenia, schizoaffective disorder, bipolar disorder, PTSD, major depressive disorder, anxiety, OCD, panic, and gender issues. After Fairmont, I completed a Post-Graduate Fellowship in Psychiatry at Kaiser Permanente, where I worked with adults, children, and families in group and individual settings.
