Obsessive-compulsive disorder therapists & psychiatrists in Petaluma, CA

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.

Hi! I'm Christina Stelly, DNP, APRN, PMHNP-BC — a board-certified Psychiatric Mental Health Nurse Practitioner based in Martinez, CA. With over 15 years of clinical experience across inpatient psychiatry, maternal health, and advanced practice, I am deeply committed to delivering compassionate, evidence-based mental health care to every person I serve.

I specialize in treating schizophrenia, bipolar disorder, PTSD, depression, anxiety, etc.

My academic background includes a Post-Certificate DNP in Psychiatric Mental Health from the University of Illinois Chicago, a Doctorate of Nursing Practice from Texas Tech University, and a Master of Science in Nursing from Touro University. I also completed an intensive NP residency focused on advanced psychiatric care, crisis stabilization, and forensic psychiatry, which further strengthened my clinical expertise.

Earlier in my career, I specialized in maternal mental health, serving as a Patient Care Director for high-risk obstetric populations and contributing to perinatal mental health policy at the state and national levels. This background gives me a uniquely broad, whole-person perspective on psychiatric care across the lifespan.

My approach is grounded in trauma-informed, individualized care. I take time to fully understand your history, concerns, and goals before collaboratively building a treatment plan tailored to you. I have also served on health policy committees and presented at national nursing conferences, reflecting my commitment to psychiatric care.

Hello! I am Registered Yoga Teacher, Clinical Supervisor & Consultant, as well as a Certified Focusing-Oriented Expressive Arts Practitioner.

I have almost a decade of experience working with children, adults, couples, and families in a therapeutic capacity. I specialize in trauma and family work. I am an integrative psychotherapist – integrating art therapy, play therapy, sand tray, mindfulness, astrology, spirituality, and more into therapy.

I’m Thomas Moore, LPCC, a licensed professional clinical counselor providing therapy for individuals navigating anxiety, trauma, emotional overwhelm, identity development, and complex relational patterns. Many of the people I work with feel stuck in repeating cycles such as overthinking, people pleasing, emotional shutdown, intense reactions, or difficulty maintaining stable relationships even when they logically understand what they should do. My goal is to help you translate insight into real change.

My approach is structured and compassionate. I integrate evidence based methods including cognitive restructuring, emotional regulation training, interpersonal effectiveness skills, and trauma informed therapy. Sessions focus on understanding why your brain reacts the way it does and building practical tools you can actually use outside the therapy room. This is not only about talking through problems but learning how to respond differently when they show up in real life.

I work well with clients who want more than passive support and are ready to build skills, increase self awareness, and interrupt patterns that no longer serve them.

What clients should know before starting

Therapy with me is collaborative and active and you will learn strategies rather than only venting. We will work on understanding both the emotional and neurological side of your reactions. Sessions focus on present day functioning while also addressing past experiences that still affect you. I may gently challenge patterns when it supports growth while maintaining a supportive and respectful space. Progress often comes from small repeated changes rather than sudden breakthroughs.

If you are looking for therapy that combines validation with practical change, we will likely work well together.
