General Information

About Us

Jonathan Leibowitz, MD, PC is a division of Excelsior Integrated Medical Group. Dr Leibowitz has been in practice for over 20 years and is both a dedicated and engaging Primary Care and physician and a Fellowship trained Nephrologist. Dr. Leibowitz is a graduate of the prestigious and selective 7 year SUNY Downstate BA/MD Program. He completed both his Residency in Internal Medicine and Fellowship in Nephrology at the Icahn School of Medicine at Mount Sinai; he is Board Certified in both Internal Medicine and Nephrology by the American Board of Internal Medicine.

After spending several years in leadership, research, and teaching positions in Nephrology, Dr Leibowitz established his boutique Primary Care practice in Brooklyn, NY. The practice strives to blend state-of-the art medicine and technology with the “art of medicine” – an art Dr. Leibowitz feels is quickly disappearing from our landscape. To this end Dr. Leibowitz, certified in physician acupuncture, if appropriate, will often harmonize alternative options into a patient’s treatment plan.

What is probably the most unique aspect of Dr. Leibowitz' practice stems from his own personal and successful battle with Bone Cancer. Dr. Leibowitz has 'experienced the experience' and incorporates his own experiences (several, potentially game changing and major surgeries, months of grueling chemotherapy, and all that goes along with that) into his approach to patients and disease.
