Hello! I provide psychiatric evaluations and medication management for children (6+), teens, adults, and seniors. Life can feel overwhelming when anxiety, depression, ADHD, or bipolar mood swings affect your energy, focus, relationships, and daily life. I believe mental health care should feel supportive, comfortable, and personalized. As a board-certified PMHNP with over five years of experience, I help individuals struggling with anxiety, depression, ADHD, autism, bipolar disorder, OCD, PTSD, eating disorders, schizophrenia, and other mental health concerns.
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.
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.
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:
Above all, I believe in partnering with you as a collaborative ally. My practice is a safe, sophisticated space where clinical excellence is a given, and we work together to help you rediscover hope and transformation.
