Addiction therapists & psychiatrists in San Jose, CA

Dr. Clancy Cavnar is a licensed psychologist with specializations in addictions and psychedelic therapy. She has worked with a wide variety of people and with a broad range of diagnoses and life situations that therapy can help with. She offers a comprehensive assessment and treatment focused on a client’s individual needs. Dr. Cavnar is empathic and compassionate, and therapy with her is an exchange of ideas, with deep listening and non-judgmental acceptance.

I have worked with a variety of clients of all ages and cultural backgrounds. My primary focus has been on individual therapy but enjoy working with couples and families as well. I bring empathy, unconditional positive regard, and genuineness to all of my therapy sessions.

I’m a doctoral-prepared, board-certified Psychiatric Mental Health Nurse Practitioner who works with clients across the lifespan. I earned my Doctor of Nursing Practice degree from the University of Arizona and have experience caring for individuals in outpatient, intensive outpatient, and higher-acuity mental health settings. My background includes treating anxiety, depression, ADHD, trauma-related concerns, OCD, mood disorders, and substance use. I take a thoughtful, practical, and individualized approach to care, with the goal of helping clients feel understood, safe, supported, and comfortable being honest when feeling emotionally vulnerable.

I'm Michael, a board-certified Psychiatric Mental Health Nurse Practitioner passionate about providing integrated care for complex mental health challenges, including ADHD, autism spectrum disorders, OCD, personality disorders, PTSD and trauma, schizophrenia and psychosis disorders, substance use disorders, depression, anxiety, panic disorders, mood disorders, and bipolar conditions. My practice recognizes that these conditions are deeply interconnected in ways requiring specialized understanding.

I chose to specialize across this broad spectrum because I understand how neurodivergence intersects with trauma responses, how personality patterns emerge as adaptive mechanisms, how substance use can complicate other presentations, and how psychotic symptoms may develop in vulnerable individuals. Whether you're in recovery while managing other conditions, discovering neurodivergence later in life, or dealing with multiple diagnoses that influence each other, I bring the expertise needed to see the complete picture.

My approach emphasizes both evidence-based treatments and the healing power of being truly understood by someone who isn't intimidated by complexity. I recognize that seeking help for multiple or stigmatized conditions takes tremendous courage, especially after disappointing experiences with other providers who may have felt overwhelmed by your needs.

I am open, approachable, and committed to listening carefully to your experiences without judgment. I believe that each person carries a unique story, and my goal is to provide a supportive space where you feel heard, understood, and encouraged as you navigate life’s challenges and opportunities for growth. Together, we can explore what is most important to you and work toward creating a life that feels meaningful, authentic, and aligned with your values.

My background includes earning a Ph.D. from the University of California, Berkeley, along with a lifelong appreciation for personal growth, nature, and the healing power of connection. Growing up learning to surf fostered a deep respect for the ocean and the lessons it offers about resilience, balance, and adapting to life's changing conditions. These experiences have shaped my belief in the importance of honoring each individual’s journey and recognizing that growth often comes through both challenge and reflection.

For nearly 13 years, I worked as a psychotherapist at a mens' long term substance abuse treatment program, The Fellowship Center, Inc. in Escondido California. I obtained several certifications as a drug and alcohol counselor, but I relied primarily on my training as a Licensed Marriage and Family Therapist to perform individual psychotherapy for residents in the treatment program.

I also have obtained training in Eye Movement Desentitization and Reprocessing (EMDR) which I believe provides a robust treatment intervention for trauma. I now have 10 years experience using EMDR both in person and by telehealth with more than one hundred fifty clients.

I also have a strong interest in mindfulness and somatic interventions which I believe are essential in the integration of the treatment of both substance abuse and trauma.

In addition to trauma and substance abuse, I most frequently work with clients suffering from anxiety, depression, or complex grief.

Finally, I enjoy working with clients who are struggling in the midst of major life transitions.

Hi! Im Mike Strauss and I specialize in anxiety, PTSD, depression and substance abuse. With my own background as an addict now with 17 years clean and sober, I organically found my purpose as a clinician. What initially started with drug and alcohol counseling immediately turned into something bigger, as I pursued a master’s degree in social work. Understanding that addiction is but a symptom of underlying fears and traumas resulting in mood disorders, I was able to REALLY look at myself as I encourage my clients to do during their journeys toward self-realization.

Marche Williams is a Licensed Marriage and Family Therapist, accomplished behavioral health leader, and Founder of SOZO Child & Family Wellness.

Marche’s professional mission is rooted in a simple belief: meaningful change occurs when people are given the right combination of support, practical tools, accountability, compassion, and hope. Whether leading behavioral health programs, developing clinicians and staff, or building innovative services through SOZO, she remains committed to helping individuals and families move beyond surviving toward healing, growth, and lasting transformation.

I am dedicated to helping individuals make meaningful, lasting changes by developing coping skills that fit their unique life experiences. With over 20 years of experience in addiction treatment and mental health services, I bring a grounded, compassionate, and client‐centered approach to therapy.

My specialties include substance use disorders, anxiety, PTSD, trauma, and co‐occurring mental health challenges.

I focus on the whole person—mind, body, and environment—because growth in one area naturally supports growth in all others.

I’m here to make this journey feel gentle, welcoming, and human. I keep things clear and simple so you can focus on what matters, not the overwhelm. My style is warm, encouraging, and a little poetic—because softness helps us breathe. Let’s take this step together, one calm moment at a time.
