ADHD therapists and psychiatrists in Northridge, 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.

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.

I highlight your strengths in our sessions. Just think of me as your emotional cheerleader. I want the best for you, whatever that may be.
