Obsessive-compulsive disorder therapists & psychiatrists in Atascadero, CA

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.

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.

I’m a Licensed Marriage and Family Therapist in California. I’ve worked 10+ years in community mental health and social work in the Central Valley. I work with trauma, feeling stuck, depression, anxiety, adhd, relationship challenges.

Non-Judgmental Psychotherapy - A safe place is provided for individuals to explore their thoughts, feelings, and behaviors to foster self-awareness and facilitate positive changes related to life challenges. Additionally, therapy for those who want to address issues of unwanted relationships with sex, such as pornography, sexting, minor attraction, infidelity, etc. is available.

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.

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.

I can understand first-hand how difficult it can be to reach out for help for the first time. I believe in the importance of "practicing what you preach" and I have been the client in the room who needs extra support. I invite you to give yourself a chance, try something new, and gain a healthy perspective on how to address complicated moments in your life.

My goal is to create a space where you feel seen, understood, and supported. I believe mental wellness is an essential part of overall health, and that healing begins by moving from survival to thriving through nervous system regulation, processing past experiences, and strengthening the mind-body connection. Meaningful change and healing happens within a strong therapeutic relationship built on trust, authenticity, and collaboration. Whether you're navigating anxiety, depression, trauma, relationship challenges, addiction, performance anxiety, work-related stress... or simply feeling overwhelmed by life's demands, we'll work together to build insight, process difficult experiences when appropriate, develop practical coping skills, and create meaningful, lasting change.
