Obsessive-compulsive disorder therapists & psychiatrists in Carlsbad, CA

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.

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.

As a Licensed Marriage and Family Therapist, I have spent the past eight years walking alongside individuals as they navigate some of life’s most difficult chapters. I have had the honor of supporting survivors of trauma and abuse, individuals living with depression, anxiety, and ADHD, victims of crime, and those carrying the unique challenges of immigration-related stress.

I believe every person has a story that deserves to be heard with compassion and without judgment. My role is not to tell you who to become, but to help you reconnect with the strength, resilience, and wisdom that already exist within you. Together, we create a space where healing can unfold, wounds can be understood, and hope can begin to take root again.

Whether you are carrying the weight of past experiences, feeling overwhelmed by the present, or searching for a path forward, you do not have to walk that journey alone.

You deserve support that meets you where you are and helps you get where you want to be. As a licensed Marriage and Family Therapist, I empower individuals to overcome anxiety, depression, ADHD, Autism Spectrum Disorder, suicidal ideation, self-harm, and other mental health challenges. With experience treating PTSD, burnout, OCD, panic attacks, anger management concerns, substance use and addiction, gender identity issues, and major life transitions, I provide compassionate, evidence-based care tailored to your unique needs. Therapy can be the beginning of a healthier, more fulfilling chapter—and I'd be honored to support you.

I provide an inclusive, affirming, and culturally responsive space where clients feel seen, heard, and valued. Through ongoing training in anti-racism, spirituality, and LGBTQIA+ affirming care, I strive to offer compassionate, evidence-based support. I believe you are the expert in your life, and I am here to support your healing and growth.
