Find a psychiatrist in Colorado — covered by insurance

I am a trauma-informed psychiatric nurse practitioner with training from Columbia University and Frontier Nursing University. My background includes psychiatric nursing across all levels of care, as well as six years in community health serving underserved and marginalized populations. I work with children, adolescents, and adults, and have extensive experience treating mood and anxiety disorders, trauma-related conditions, and eating disorders, along with psychotic disorders, substance use concerns, and personality-related challenges. My training allows me to integrate medical knowledge, functional and nutritional psychiatry, community services, and psychotherapy to provide comprehensive, personalized care.

Welcome! I’m honored you’re considering care. I’m a doctorally prepared Nurse Practitioner with dual board certification in Adult-Gerontology Acute Care and Primary Mental Health. As a former first responder, I bring firsthand understanding of the unique stressors faced by those in high-intensity roles. I take a trauma-informed, person-centered approach to care. I specialize in working with individuals navigating complex emotional landscapes, including first responders and members of the LGBTQ+ community. My goal is to create a safe, affirming space where you feel heard, respected, and empowered to take steps toward healing.

I began my career as a Fulbright Scholar, conducting research on traditional medicine in Sochi, Russia. I presented my work at the United States Embassy in Moscow, highlighting cross-cultural perspectives in healthcare and integrative practice.

After completing my grant, I attended New York University (NYU). I then completed a residency at M.D. Anderson Hospital in Houston, Texas. I went on to earn my doctorate from the University of San Diego, California, where I focused on digital telehealth treatment for psychiatric care.

I am passionate about working with Veterans and individuals experiencing Depression, Anxiety, and Mood Disorders. In 2023, I completed CIIS training in psychedelic-assisted therapy. In 2025, I was among the first providers in Colorado and in the country to become licensed as a psilocybin facilitator.

Hello! I'm Idowu Mary Oni, a Board-Certified Psychiatric Nurse Practitioner (PMHNP-BC) committed to delivering personalized, compassionate mental health care. With a strong foundation in nursing, I specialize in supporting individuals as they navigate mental health challenges and work toward greater emotional well-being. I'm honored to be part of your journey and look forward to helping you reach your goals with care and understanding.

Born and raised in Brooklyn, New York, I completed my medical training at NYIT College of Osteopathic Medicine. As an osteopathic physician, I practice with a holistic lens—integrating mind, body, and spirit—and value personalized, relational, and evidence-based care. I completed my psychiatric residency at St. Elizabeths Hospital in Washington, DC, a forensic psychiatric hospital often referred to as “the ICU of psychiatry” for its work with individuals facing chronic, treatment-resistant conditions. After residency, I spent three years in outpatient psychiatry within large corporate settings and ultimately transitioned to an eating-disorder hospital, seeking work aligned with depth, integrity, and true patient-centered care.

As a first-generation Ukrainian Jew and a native Russian speaker, I hold lived experience with immigration, intergenerational trauma, and cultural stigma surrounding mental health. This background informs my compassion, humility, and commitment to meeting patients where they are.

I am a board-certified Family Nurse Practitioner and a Psychiatric Mental Health Nurse Practitioner. I treat patients struggling with depression, anxiety, panic disorder, bipolar disorder, PTSD, ADHD, addiction, OCD, thyroid disease and hormone imbalance. I enjoy working with children, adolescents, adults and geriatric patients. I also provide genetic testing for those patients who have struggled with limited response to medications or side effects.

My priority is to provide a safe, compassionate, and non-judgmental space where you feel heard, respected, and supported. With over 40 years in healthcare—including service as a former Navy Nurse Corps Officer and retired military veteran—I bring values of resilience, trust, and teamwork into every therapeutic relationship. I view care as a partnership and work to empower you to take an active role in your mental health.
