New & Established Patients Call

As a physician, I strive to address both respiratory and sleep disturbances in my patients in order to provide more comprehensive care. I work with my patients and their families to help improve their health and overall wellbeing. Additionally, I understand the importance of medical education and hope to use my training experience at multiple academic medical centers around the country to teach students, residents and fellows here at the Medical College of Wisconsin.

Clinic Locations


I was born and lived in the Soviet Union until I came to the United States when I was 10.  I completed my residency in internal medicine here at the Medical College of Wisconsin (MCW), completed my pulmonary medicine fellowship at Georgetown University, and my sleep medicine fellowship at George Washington University before returning to MCW.  As an assistant professor, I work closely with medical students, residents and fellows in order to share my education and experiences with future physicians. 

In my free time, I enjoy practicing martial arts, playing chess, and spending time with my wife and twins.
