Jonathan S. Leibowitz, MD, is a primary care provider offering evidence-based, integrative medicine to patients in the Borough Park area of Brooklyn, New York. With board-certifications in primary care, nephrology, and internal medicine, Dr. Leibowitz uses his vast body of experience to promote the health and well-being of his patients. He treats a variety of illnesses, including chronic conditions like asthma and diabetes.

Dr. Leibowitz holds a medical degree from the State University of New York (SUNY) Downstate Medical Center in Brooklyn. After graduation, he remained in New York City, completing a residency in internal medicine and a fellowship in nephrology at the Icahn School of Medicine at Mount Sinai, a leader in medical and scientific training.

Throughout his medical career, Dr. Leibowitz has made significant contributions to the fields of internal medicine and nephrology. He has conducted extensive studies, participated in several research initiatives, and published articles on topics related to nephrology. He also has lectured and delivered several presentations on the subject. He maintains an affiliation with the Maimonides Medical Center in Brooklyn and is certified in medical acupuncture.

Dr. Leibowitz's unique approach to patient care stems from his successful battle with bone cancer. He has incorporated his own experiences — which included a series of major surgeries and months of grueling chemotherapy — into his patient-centered approach. As a doctor, he’s had the uncommon experience of standing in his patients’ shoes and brings this refreshing perspective into the exam room when he cares for his patients.

Today, Dr. Leibowitz leads a practice grounded in the principles of scientific, integrative, and open-minded medical care. The practice offers a full array of procedures typical in a comprehensive primary care setting. Services include EKGs, pulmonary function tests, earwax removal, pre-surgery checkups, back pain diagnosis and treatment, cancer screenings, vaccinations, annual physicals, and targeted weight loss plans.
