Find a psychiatrist in Denville, NJ — covered by insurance

Are you suffering from anxiety, depression, bipolar disorder, psychosis, PTSD, OCD, ODD, ADHD, Alzheimer's Dementia, and substance abuse? My name is Patrick Obinna Oledimmah, PMHNP-BC. I can provide psychiatric services such as psychiatric evaluations, medication management, and individual psychotherapy. I am certified in Medication Assisted Treatment (MAT) to prescribe Suboxone.

I’m a board-certified Nurse Practitioner with over a decade of experience working in ICU. My background in critical care shaped how I understand the deep connection between physical and mental health, especially how stress, trauma, and anxiety often show up in the body. I transitioned into psychiatry after witnessing firsthand the emotional toll the pandemic had on patients, families, and healthcare workers. It became clear to me that supporting people’s mental health is just as essential as treating physical conditions.

**Important for New Jersey patients seeking STIMULANT treatment:

Due to New Jersey state regulations, patients prescribed stimulant medications are required to attend an in-person visit at least once every three months. These visits are scheduled at my SoHo office in Manhattan.

Please note that there is a $100 facility fee for in-person visits to cover the cost of the clinical space. This fee is separate from insurance and is due at the time of the visit.**

I’m a Board-Certified Psychiatric-Mental Health Nurse Practitioner (PMHNP-BC) with nearly two decades of experience supporting individuals and families through behavioral health and substance use challenges. My approach is grounded in trauma‐informed care, cultural sensitivity, and meeting people exactly where they are. I believe healing happens when people feel seen, heard, and supported without judgment.

I completed my Master of Science in Nursing at Monmouth University and have worked across inpatient, outpatient, community, and addiction treatment settings. My background includes detox and MAT services, crisis stabilization, care coordination, and leading interdisciplinary teams. I also serve as a clinical instructor for BSN students, which keeps me connected to education, mentorship, and the next generation of nurses.

Your mind and body are speaking—are you listening? As a board-certified Psychiatric Mental Health Nurse Practitioner with over a decade of experience in high-stakes intensive care, I understand what many overlook: mental and physical health are inseparable.

In critical care, I saw how stress, trauma, and anxiety manifest in the body—tight chests, sleepless nights, unexplained pain. And when the pandemic hit, I witnessed the silent emotional suffering of patients, families, and healthcare workers alike. That moment changed everything.

I chose psychiatry because healing your mind is just as vital as healing your body. If you’re feeling overwhelmed, exhausted, or like no one sees what you’re carrying—you don’t have to hold it alone. I’m here to help you reconnect, restore, and rise.
