Who is Zainab Koroma?
Zainab Koroma, PMHNP-BC, FNP-C is board-certified as both a psychiatric and a family nurse practitioner and co-owns Optimal Health York. She treats children, teens and adults ages 8 and up in person in York, PA and by telehealth in Pennsylvania and Maryland, combining mental health and primary care..
A career built in the hardest places
Zainab Koroma was born in Sierra Leone and emigrated to the United States in 1996. She became a nurse, then a nurse practitioner, then a dual-board-certified provider in two specialties most clinicians never combine. Psychiatric mental health nursing on one side, family medicine on the other — because the patients she kept meeting needed both, and the system kept making them choose.
Her career has taken her through some of the hardest healthcare environments there are: correctional facilities, long-term care, and 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.
At Optimal Health York, Zainab sees patients in person at the York office on East Market Street, and via telehealth in Pennsylvania and Maryland. She treats anxiety, depression, child and adolescent mental health, and the everyday primary care that holds it all together — physical exams, chronic condition management, and medication management. She can begin psychotherapy herself and refers to a specialist when a patient's needs fall outside her focus.
Zainab's approach is integrative. Anxiety from a thyroid. Depression from chronic pain. A teenager with both ADHD and asthma. She doesn't ask patients to split themselves into a "mental health visit" and a "primary care visit" — both halves of the conversation happen in the same room, with the same provider, every time.
