Timothy Yen, Psy.D.

Hello! My name is Dr. Timothy Yen, a licensed psychologist based in the San Francisco Bay Area. I currently work at Kaiser Permanente since 2014 and believe in the impact of therapy both brief and long-term. I am passionate about empowering others, helping increase clarity into difficult situations, providing practical resources and recommendations, and ultimately helping people create meaningful lives and relationships. I completed my doctorate in clinical psychology at Azusa Pacific University in 2014 with an emphasis in family psychology and consultation. Prior to college, I enlisted in the US Army as a mental health specialist for over 8 years.

My theoretical orientation is primarily family systems theory and cognitive behavioral therapy (CBT) but often incorporate other theories and skills (e.g., positive psychology, psychodynamic, Dialectical Behavioral Therapy, Acceptance Commitment Therapy, etc.) for a more integrated and holistic treatment. I believe in evidenced based practices and the importance of identifying issues and treatment goals early on in the session. I offer assistance in individual, couples, and child/families therapy on a wide variety of issues to include treatment for depression, anxiety, ADHD, PTSD, parenting skills, social skills, divorce, bereavement, and anger management. I am also trained in basic Eye-Movement Desensitization Reprocessing (EMDR) Therapy and Prepare-Enriched, a faith-based marriage preparation and enrichment program.

On a more personal note, I enjoy spending time with my wife and cat, playing and listening to music, looking at and maintaining aquariums, trying new ethnic foods, traveling, hiking, playing volleyball, and watching movies and animation. I look forward to meeting you and coming along side you to create a life worth living!

Laura Avila, Ph.D.

My name is Laura Avila, Ph.D. and I am a licensed clinical psychologist. I received a M.A. and Ph.D. in Clinical Psychology from Northern Illinois University.  I also completed a fellowship in Health Psychology at San Antonio Military Medical Center (SAMMC), formerly Brooke Army Medical Center (Ft. Sam Houston) in San Antonio, Texas. I have over 20 years of experience in the diagnosis and treatment of psychological problems, including depression, bipolar disorders, and anxiety disorders such as PTSD, OCD, and Panic Disorder.  Other areas of expertise include stress management, chronic disease management, sleep disorders, psychological assessments, memory/dementia assessment, medical phobias, and chronic pain management.  I have worked at a veterans administration hospital, active military hospital, geriatric long-term care facilities, and private practice. As a clinical psychologist and director of the Health Psychology Fellowship at SAMMC, I acquired training and experience in evidence-based treatments and stayed current on the latest research in the treatment of psychological problems. My theoretical orientation is primarily cognitive-behavioral; however, I often incorporate elements of other therapies to provide patients with the most effective treatment for their unique situation. I also hold a M.S. degree in Clinical Psychopharmacology which has enabled me to discuss and manage psychotropic medications and medication interactions with  patients and their physicians. I am licensed in Texas, Illinois, and California.  I am also fully bilingual in Spanish. I very much enjoy working with patients and their families; and feel very blessed to be able to do so through Eastside Christian Counseling Center.

I am married to an Army chaplain.  My family and I have recently moved to California from our home base in Texas. Although a Texan at heart, I immensely enjoy exploring the beauty of California with my husband and four children. Whether you are experiencing emotional or behavioral distress, a difficult life transition, or  an unhealthy relationship, we can work together to help you find your God-given strength, voice, and hope.

Pain is real, but so is Hope.  There is always Hope. - Author unknown


Joyce Perry, LMFT

I am a licensed Marriage and Family Therapist. I earned my master's degree in Marriage and Family Therapy from Western Seminary in Los Gatos, CA. I have worked at Kaiser since 2010 and have had a private practice in Pleasanton since 2009 through which I primarily see individual adults and couples. Prior to opening my practice I worked for Children's Bureau, a non-profit mental health agency in Los Angeles County where I provided individual, group and family therapy for children and adolescents in clinic, home and school-based settings. My areas of focus include couples counseling, anxiety, depression, codependency and trauma.

I work primarily from a Cognitive Behavioral orientation but I tailor treatment for each client incorporating other orientations and interventions as appropriate. I am certified in Prepare-Enrich, a faith-based program for couples seeking pre-marital counseling or marriage enrichment. I am trained in EMDR through Laurel Parnell. I have also received training in identity formation through Dr. David Eckman. I am passionate about helping clients access the unique strengths God has given them, encouraging them in those strengths, equipping them with life-healing truth and empowering them with renewed hope.   

When not working, I enjoy spending time with my husband exploring the outdoors, finding new escape rooms and traveling to new destinations here and abroad.

Matt McKeithan, Psych Assistant

My name is Matt McKeithan and I am a licensed Psychological Assistant (under the license and supervision of Dr. Timothy Yen) and a School Behaviorist. I currently reside in Dublin, CA with my loving wife and four children. I work in multiple school systems across the valley, where I train staff members on providing behavioral support to children with disabilities. I am also Veteran of the United States Navy, and after being injured in the military, I became a Federal Police Officer for nine years. I am currently in my last year of a Clinical Psychology doctoral program at CalSouthern University in Costa Mesa, CA.

I have a passion for working with children and adolescents, and love helping them understand and navigate their feelings in a way that leads to emotional growth. I also love working with the family dynamic, and enjoy helping parents overcome hurdles related to behavioral, identity, special needs, marital conflict, and other mental health concerns. I know from personal experience of what it's like to struggle with matters like divorce, custody battles, child behavioral issues, a special needs children, family identity concerns, spiritual struggles, and everything else that comes with raising children in a healthy household, while working in the Bay Area. I believe God has blessed me with a multitude of life experiences that have allowed me to use my gifts to connect with others in need.

My theoretical orientation is primarily focused on techniques from cognitive behavioral therapy (CBT), dialectical behavioral therapy (DBT), solution-focused therapy, and family systems theory. I believe mindfulness techniques are also beneficial in bringing awareness to ones self and environment; which can be helpful when used in conduction with other techniques.

On a more personal note, I enjoy spending time playing with my children, dating my wife, meeting friends for a cup of coffee, practicing jiu-jitsu, surfing crisp waves, painting oil on canvas, listening to podcasts, making music, cooking, trying new restaurants, and diving into God’s timeless word.
