Our practice
Meet the clinicians
Prospect Park Psychiatry is a group practice in Brooklyn providing individualized psychiatric care for adults — in person and by telepsychiatry across New York. Our clinicians share one standard of care: careful, collaborative, and unhurried.
Greg Malzberg, MD
Dr. Greg Malzberg is a psychiatrist and the founder and Medical Director of Prospect Park Psychiatry. He is an Assistant Clinical Professor of Psychiatry at the Icahn School of Medicine at Mount Sinai, where he teaches and supervises alongside his clinical work in private practice.
His approach to treatment is collaborative. He works closely with each patient to understand the full picture and to develop a personalized plan that addresses their particular needs, rather than applying a one-size-fits-all protocol. He cares for adults across a wide range of concerns, with particular attention to careful diagnosis and the thoughtful use of medication.
Dr. Malzberg is also the creator of PsychoFarm, an educational platform focused on psychiatric education, and previously served as Director of Multimedia Content at Carlat Publishing — work that reflects an ongoing commitment to clear, evidence-based psychiatric teaching.

What is a Nurse Practitioner?
Nurse Practitioners (NPs) are nurses who have completed master's-level graduate training. Because most NPs have worked as nurses in a range of settings before graduate school, they bring hands-on clinical experience to their advanced role. Unlike nurses trained at the undergraduate level, NPs can diagnose and treat a wide range of conditions across the lifespan — including by prescribing medication.
