Pulmonary Medicine Clinic

Medicine is a delicate intersection of science and art. Fundamental to good patient care is the acknowledgement that the ‘right’ decision is the one obtained through mutual agreement, respect and share decision making. As a clinician, my job is to give you sound, evidence-based and compassionate advice and find ways to align my recommendations with your goals in health and well-being.

Clinic Locations


I completed medical school in Chicago and went on to complete internal medicine residency and pulmonary and critical care medicine fellowship at the Medical College of Wisconsin. I take care of critically ill patients in the ICU and also practice pulmonary medicine in the outpatient setting. In the latter, my interests focus on the diagnosis and management of patients with scarring conditions of the lung (Interstitial lung disease). I am also interested in pulmonary complications of hematopoietic stem cell transplant (HSCT) as this group of lung disorders shares many characteristics of interstitial lung disease. I am passionate about medical education and take part in the mentoring of medical students, residents and fellows. Born in Russia, I speak the language fluently. Outside of work, I enjoy travelling, good food and being in nature. Having been an urban planning/Global change major in undergrad, I am fascinated by how our built environment can influence health outcomes.
