I am a double board-certified family and psychiatric/mental health nurse practitioner. As a Family and Psychiatric Nurse Practitioner, I believe that healing begins with understanding. My goal is to create a safe, supportive space where you can share your story without judgment and work toward meaningful, lasting change. I provide individualized, evidence-based care for adults facing depression, anxiety, PTSD, bipolar disorders, ADHD/ADD, and sleep disorders.
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.
With over a decade of acute care experience as a Registered Nurse and a Master’s degree as a Psychiatric Mental
Health Nurse Practitioner, I specialize in treating mood disorders, anxiety, PTSD, neurodiversity, and medication
management.
As a Psychiatric Mental Health Nurse Practitioner, I aim to create a space where you feel heard, respected, and understood. I believe mental health care should be collaborative, practical, and tailored to your unique needs. My approach combines evidence-based treatment with real-life understanding whether that includes therapy, lifestyle changes, or medication management when appropriate. I value honesty, cultural awareness, and meeting you where you are. My goal is to help you feel more stable, confident, and in control of your mental health not just during appointments, but in your everyday life.
I’m here to make this journey feel gentle, welcoming, and human. I keep things clear and simple so you can focus on what matters, not the overwhelm. My style is warm, encouraging, and a little poetic—because softness helps us breathe. Let’s take this step together, one calm moment at a time.
Mental health has long been treated as the forgotten side of healthcare — and for me, that's exactly why it matters so much. As a Psychiatric Nurse Practitioner serving clients across California through telehealth and in-person care, I specialize in helping people navigate depression, anxiety, and ADD/ADHD. I believe that when mental health struggles go unaddressed, everything else in life suffers — and that healing is not only possible, it's necessary. When I'm not supporting my clients, you'll find me out in nature, getting lost in a good movie, or discovering new music — small reminders of the joy and balance I encourage my clients to find for themselves.


Headway makes it easy to find support for your mental health — from finding the right provider, to understanding costs, to scheduling with ease.
Finding the right psychiatrist in Murrieta starts with understanding the type of care you need. Psychiatrists are medical doctors who can diagnose mental health conditions, prescribe medication, and monitor how that medication is working over time. If you're looking for help with anxiety, depression, ADHD, bipolar disorder, or another condition that may benefit from medication management, a psychiatrist may be the right fit. Psychiatric nurse practitioners (PMHNPs) can also evaluate, diagnose, and prescribe medication, and are another option available through Headway.
With providers spread across Murrieta, Temecula, Menifee, and the broader Inland Empire, narrowing your search means thinking about what matters most to you. That could be a provider who specializes in a specific condition, someone who offers virtual appointments, or a clinician whose approach and background feel like a good match. Reading a provider's bio before booking can help you understand their style and decide if they're right for you.
Psychiatry sessions in Murrieta can be expensive without insurance. Using your in-network benefits is one of the most reliable ways to lower your out-of-pocket costs. On Headway, you can enter your insurance details to see estimated session costs upfront, and many patients pay as low as $0 per visit. Nationally, Headway partners with over 100 insurance plans, making it easier to find a psychiatrist who is both the right clinical fit and covered by your plan.
