Obsessive-compulsive disorder therapists & psychiatrists in Walnut Creek, CA

Sometimes the hardest part is not what happened. It is finding someone you can finally say it to. I offer therapy in both English and Spanish, and I work with people across all stages of life, from children and teenagers to adults and seniors. I specialize in supporting people navigating trauma, domestic violence, anxiety, depression, and the unique challenges that come with new and expecting parenthood. Wherever you are in your story, you do not have to carry it alone.

I provide empathic, compassionate care in a safe, supportive, and nonjudgmental space where clients feel heard and respected. My goal is to offer therapy you can trust—an environment where you can openly explore your thoughts, challenges, and goals while receiving understanding and supportive guidance.

I’m a licensed clinical social worker who specializes in helping children, adolescents, adults, couples, and families navigate anxiety, depression, panic, trauma, PTSD, and other life stressors. With experience in psychiatric crisis care and community outreach, I believe healing starts with feeling safe enough to show up. My goal is to offer real, judgment-free support that meets you where you are and helps you move toward lasting growth.

As a Psychiatric Mental Health Nurse Practitioner (PMHNP), I’m trained at the graduate level in mental health care across the lifespan. I assess mental health concerns, diagnose conditions, prescribe and manage psychiatric medications, and provide psychotherapy. I also coordinate care with therapists, primary care providers, and other specialists as needed.

For the past year, I've worked with adults facing serious mental health challenges at one of Los Angeles's largest public health systems, and what I've learned is that lasting change comes from relationships built on trust. Now I'm bringing that experience into private practice, where I can focus on what matters most: your individual progress. I work with people navigating anxiety, depression, and PTSD, and I offer flexible evening and weekend availability via telehealth throughout California. As a PMHNP, I'm here to support your whole mental health journey.

If you have tried therapy before without the results you hoped for, you may need a more targeted, effective approach. Over the past 15 years of my practice as a clinical psychologist, earning your trust and helping you establish a secure, empowering baseline for your care has been a profound privilege. As a former instructor at the David Geffen School of Medicine at UCLA and a provider at the UCLA Insomnia clinic, my goal is to provide more than just a space to talk—I offer the specialized, gold-standard steps necessary to create measurable, lasting change. At my practice, YCBT Services, I focus on working with adolescents, adults, and seniors who feel stuck despite their best efforts, specifically targeting generalized anxiety, social anxiety, OCD, panic disorders, and chronic insomnia. By addressing the underlying triggers that keep you on high alert, I am fiercely committed to helping you move beyond surface-level coping to reclaim your peace of mind.

My name is Dianne Fontaine, MSN, APRN, and I'm a Licensed Psychiatric Mental Health Nurse Practitioner, Board Certified (PMHNP-BC) by the American Nurses Credentialing Center (ANCC). I obtained my Master’s Degree from Walden University and has undergone advanced clinical training, equipping me to assess, diagnose, and treat a spectrum of psychiatric illnesses, as well as provide psychotherapy.

What patterns keep repeating in your life, even when part of you wants something different? I work with infants, children, adolescents, adults, and seniors, with a particular focus on experiences that are hard to put into words: the quiet accumulation of feeling disconnected or unseen, questions around adoption and family origins, infertility, the emotional weight of becoming a parent, and the grief that comes when life takes an unexpected shape. A lot of what brings people to therapy is not a single event. It builds. I trained at UCLA and bring both clinical depth and genuine warmth to this work.
