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.
Hello, my name is Alexander Valenzuela PMHNP. I specialize in psychiatric medication management and cognitive behavioral talk therapy. If you're struggling with your mental health and realize you want help, you don't have to do it alone. I am looking forward to starting the journey with you to help achieve your best self.


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 Anaheim starts with knowing what 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. Psychiatric nurse practitioners (PMHNPs) can also prescribe and manage medication. If you're looking for help with anxiety, depression, ADHD, bipolar disorder, or another condition that may benefit from medication, a psychiatrist or prescriber may be the right fit.
Anaheim has a range of psychiatric providers, but verifying insurance acceptance and availability can be time-consuming. Consider what matters most to you — whether that's a provider who specializes in a specific condition, offers virtual appointments, or is located near your neighborhood in Anaheim Hills, West Anaheim, or Central Anaheim. Reading a provider's bio can give you a sense of their approach before you commit.
Psychiatry sessions in Anaheim can be costly out of pocket, so using your in-network benefits is one of the most reliable ways to reduce what you pay. On Headway, you can enter your insurance information to see estimated session costs upfront. Nationally, Headway partners with over 100 insurance plans, and your out-of-pocket expense may be as low as $0 per session, though costs vary based on your location and exact coverage.
