Life can feel overwhelming—but you don’t have to navigate it alone. I’m here to help you regain clarity, stability, and a sense of control.
I’m Monika Delyser, a board-certified Psychiatric Mental Health Nurse Practitioner providing thoughtful, culturally sensitive care for adults experiencing burnout, anxiety, mood disorders, ADHD, and sleep challenges.
I work with professionals, entrepreneurs, students, and high-functioning adults who are dealing with anxiety, burnout, and focus challenges. Many of my clients appear “fine” on the outside but feel overwhelmed, mentally exhausted, or stuck.
Who I’m a Good Fit For: busy professionals under pressure, entrepreneurs and high performers, college and graduate students, adults seeking structured, goal-oriented care.
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 board-certified Psychiatric-Mental Health Nurse Practitioner and my practice is dedicated to supporting teenage girls (ages 14+) and young women across California. Beyond my clinical background in specialized hospital units, I am someone who values a high-energy, balanced lifestyle. When I’m not in the hospital, you’ll likely find me rock climbing or weightlifting—activities that keep me grounded and remind me of the importance of resilience. I’m also a big sci-fi fan and love to geek out over a great movie or a deep-dive read. As a bilingual provider, I offer services in both English and Spanish, specializing in helping my patients manage ADHD, hormone related emotional mood swings, and binge eating tendencies.
My approach to mental health care centers entirely around you. True healing happens when trust, safety, and collaboration come together. Whether you are navigating severe depression, managing long-term anxiety, or recovering from trauma, my goal is to provide a premium, supportive environment where you feel heard and empowered to reclaim a stable, fulfilling life.
As a board-certified adult psychiatrist, I bring unique depth to my clinical practice. I earned both my MD and PhD from the Albert Einstein College of Medicine, grounding my approach to medication management in advanced scientific research and evidence-based medicine.
My leadership and clinical training within the University of Texas Health System—including roles as Chief Resident, Assistant Medical Director, and Assistant Professor—deeply shaped my view of mental health. Having cared for individuals across institutions like MD Anderson, Memorial Hermann, the Dunn Behavioral Sciences Center, and Maui Memorial Medical Center, I possess the outpatient and inpatient expertise required to manage complex clinical cases with complete confidence.
I provide convenient, high-quality telepsychiatry and virtual care for adults (ages 18 and older) actively located in Texas, California, Hawaii, and Alaska.
Primary Clinical Focus Areas:
