Bipolar disorder therapists & psychiatrists in Gilbert, AZ

Hello, I'm here to help you facilitate healing and arrive at your healthiest self. We will work together, to arrive at your destination; wherever that may be.

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.

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.

Outside of my work as a therapist, I enjoy spending time outdoors, riding my horses, and being with my family. These activities help me stay grounded and connected to what matters most in life. I value balance, authenticity, and meaningful relationships, and I bring those same values into my work with clients. I strive to create a welcoming, supportive environment where clients feel comfortable being themselves and working toward their goals.

I have found my own personal healing to be intimately connected to nature, and it is here that I believe that we can all begin to rediscover our intrinsic humanity and let go of those things that distract us from our higher selves. In my spare time, I work as an outdoor educator and manage my own private practice and guide Outdoor Retreats

I believe it is helpful and important to translate what is discussed in session and in telehealth meetings into lived experience and real change.

As a provider with 40+ years of sobriety, I offer real solutions for substance abuse problems. What makes my practice unique is my personal and professional background in disabilities that goes decades in Autism, Intellectual Disabilities, hearing and vision impairments, severe mental illness (psychosis) and cerebral palsy. In addition, I have completed Certificates In Jungian Psychodynamic Psychotherapy with adolescents and Young Adults, TF-CBT (trauma focused cognitive behavioral therapy) and Compassionate Bereavement Care. My education includes a M.S. in Special Education at Johns Hopkins, post-graduate certificate in Behaviors in Autism from University of Massachusetts Lowell, a MSW from Western New Mexico University, and a Ph.D. in Political Science from University of Southern California. In addition, I serve all ages.

Feeling overwhelmed, stuck, or worried about your child or family? I’m a Licensed Professional Counselor with 20+ years of experience helping children, parents, and caregivers through big feelings and life changes. As a former elementary school counselor and certified K–12 art teacher, I understand the school, social, and family pressures kids and teens face.

I provide compassionate, confidential psychiatric care designed to help you feel supported and understood. Each treatment plan is personalized, using evidence-based approaches tailored to your unique needs and goals. My goal is to create a safe, judgment-free space where we can work together to manage challenges such as anxiety, depression, mood changes, or sleep issues. Appointments are available virtually for your convenience.

I am a Licensed Professional Counselor with a Master's degree in Professional Counseling from Grand Canyon University and 18 years of experience in behavioral health and addiction services. Throughout my career, I have worked with individuals facing substance use challenges, mental health concerns, life transitions, and personal struggles that can leave people feeling stuck, overwhelmed, or disconnected from who they want to be.

I specialize in working with adults experiencing addiction, anxiety, depression, self-esteem concerns, men's issues, LGBTQ+ concerns, relationship challenges, trauma, and major life transitions. I am passionate about helping clients discover their strengths, develop healthier coping skills, and create meaningful, lasting change.

I believe that healing happens when people feel accepted, understood, and supported. My goal is to provide a safe, inclusive, and affirming environment where clients can explore their experiences without judgment. No matter how difficult things may feel today, I believe there is hope for growth, healing, and recovery.

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