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.
Hi, I’m a psychiatric nurse practitioner who believes everyone deserves to feel heard, supported, and treated with kindness. I create a warm, welcoming, and judgment-free space where you can feel comfortable being yourself. I work with clients experiencing anxiety, depression, stress, mood changes, and other mental health concerns. Along with medication management, I also use supportive therapy techniques, including CBT and motivational interviewing, to help clients build healthy coping skills and feel more confident in their daily lives.
It is my prayer to build a practice that helps you reach a place where your mental health is truly at the forefront. My hope is that with each appointment—and each day—you feel supported in moving closer to the best version of yourself.
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.
I am a board-certified Psychiatric Mental Health Nurse Practitioner (PMHNP-C) providing compassionate, evidence-based care through telehealth. My background includes experience in emergency care and mental health treatment. I work with adolescents and adults experiencing anxiety, depression, trauma-related conditions, and mood disorders. I take a collaborative and supportive approach and work closely with clients to develop personalized treatment plans focused on improving emotional well-being.


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 Newport Beach starts with understanding the type of care you need. Psychiatrists are medical doctors who can diagnose mental health conditions, prescribe medication, and sometimes provide talk therapy. Psychiatric nurse practitioners (PMHNPs) also diagnose, prescribe, and manage medication. If you're looking for help with anxiety, depression, ADHD, bipolar disorder, or other mental health concerns, either provider type may be able to help, and a qualified healthcare professional can help determine the right fit. On Headway, you can review detailed bios to learn about each provider's specialties, approach, and credentials before booking.
Newport Beach is home to a range of mental health providers serving the broader Orange County area, including nearby communities like Costa Mesa, Irvine, and Huntington Beach. When choosing a psychiatrist, consider what matters most — whether that's a provider who specializes in a specific condition, someone who offers virtual appointments, or a practice close to your neighborhood. A free phone consultation can help you decide if a provider is the right match before you commit to a session.
Psychiatry in Newport Beach can be expensive without insurance coverage. Using your in-network benefits is one of the most reliable ways to reduce what you pay per session. On Headway, you can enter your insurance information to see estimated costs upfront, and your out-of-pocket expense may be as low as $0 per visit. Nationally, Headway partners with over 100 insurance plans, making it easier to find a psychiatrist who fits both your clinical needs and your budget.
