York, PA · About Our Practice · Founded 2024
Two providers. One mission.
Optimal Health York is an independent psychiatric and primary care practice at 111 East Market Street, Suite 201, York, PA 17401. It is owned by two board-certified nurse practitioners, Abu Koroma, PMHNP-BC, CRNA, and Zainab Koroma, PMHNP-BC, FNP-C. We see patients ages 8 and up, in person in York and by telehealth.
Abu and Zainab Koroma have spent their careers working inside large healthcare systems — hospitals, correctional facilities, long-term care, the VA, military medicine. Those settings taught them what excellent clinical care looks like. They also taught them what gets in its way: 15-minute slots, productivity targets, patients passed from face to face, mental health treated as a separate department from primary care.
They opened Optimal Health York Services in York to do it differently. Longer visits. The same provider every time. Mental and physical health treated as one conversation. Care measured by how patients feel, not by how many of them moved through the door.
The practice is independent and locally owned. There is no parent company, no corporate quota, no out-of-state board. When you see a provider here, you're seeing one of the two people whose name is on the door — and they answer to you.
First visits are unhurried. Follow-ups are long enough to actually talk.
Anxiety from a thyroid. Depression from chronic pain. Both halves, same room.
Continuity is how trust gets built and how care actually works.
Whatever brought you here, we've heard it. No need to perform okay-ness.
Veteran-founded. We understand the culture and the language.
We accept all major insurances. Call today to confirm your insurance. (717) 202-2285. Self-pay rates listed openly. No surprise bills.
Both Abu and Zainab are board-certified nurse practitioners with hospital and acute-care backgrounds. Both have spent years inside healthcare systems — and both opened this practice for the same reason. Their day-to-day specialties just happen to complement each other.
Abu came to psychiatry by way of anesthesia — a clinical background that demands precision, calm, and a deep understanding of how medications actually move through the body. Combined with his time as a deployed Army medic, that gives him a steadiness patients tend to feel right away. He has a particular focus on veterans, first responders, and healthcare workers: people whose work doesn't leave room to fall apart.
Zainab is dual-board-certified in both psychiatric and family medicine — which sounds technical, but means something simple: she can take care of your mind and your body in the same room. Her career has taken her through some of the hardest healthcare environments there are, from correctional facilities to long-term care to acute hospitals. What she took from all of them is the same thing: that the patients who get overlooked are usually the ones who need the most patience. She brings that here.
If your question isn't here, call (717) 202-2285 — someone real will pick up.
