I’m a board-certified Psychiatric Mental Health Nurse Practitioner providing thoughtful, evidence-based medication management for teens and adults (6+).

My goal is to provide a safe environment for my clients to come and talk about their thoughts, behaviors, and emotions, and work towards positive self-acceptance and love.

With over 36 years in behavioral health, I've worked across inpatient, outpatient, corrections, education, and management settings — with children, adolescents, adults, and individuals navigating substance use and serious mental illness. But what drives me isn't my resume; it's this: mental illness is a bully, and no one deserves to be bullied. Nobody asked for it, and there is real courage in asking for help. I want to be a rock upon which mental illness breaks — helping people feel heard, seen, and able to enjoy life again. When I'm not working, you'll find me hiking, backpacking, or spending time with my dogs.

I am licensed in Arizona and Wisconsin with 40 years of professional work experience. I have experience in helping clients with stress and anxiety, relationship issues, trauma and abuse, & depression. I specialize in treating gambling and behavioral addictions. I believe in treating everyone with respect, sensitivity, and compassion. I will tailor our dialogue and treatment plan to meet your unique and specific needs. Taking the first step to seeking a more fulfilling and happier life takes courage. I am here to support you in that process.

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.

I am a Licensed Clinical Social Worker in California with a doctorate, a master of science in gerontology and healthcare, and certification in yoga therapy. My clinical focus is people living with serious illness, cancer, and the psychological and existential dimensions of a significant medical diagnosis.

I bring my own lived experience with malignant brain cancer to this work. That shapes how I understand fear, uncertainty, and what it means to confront something that threatens not just your life but your sense of who you are. I see clients in private practice and volunteer at local cancer centers.

I'm Sam, a therapist with over 20 years of experience specializing in trauma, substance

use and addiction recovery, anxiety, and depression. I grew up and trained in Arizona —

earning my MSW from Arizona State University — and I've spent my career working with

people navigating some of the hardest chapters of their lives. I have been a clinical director at several clinics over the past 6 years while also providing direct care. I work with adults,

adolescents, children, and seniors, and I provide affirming care for clients who identify as

LGBTQ+ or those navigating gender identity and transgender experience. My style is

energetic, open-minded, and genuinely empowering — I believe therapy should leave

you with more than just insight. You should leave with skills you can actually use.

Down to earth and very open minded. I believe in complete transparency and accountability.
