Welcome to GPG

Founded by Lawrence D. Kaplan M.D. in 1983, Gwinnett Pulmonary Group has grown to become the largest pulmonary group in Gwinnett County.

We have 10 physicians specializing in Pulmonary Medicine, Critical Care Medicine and Sleep Medicine.

We are dedicated to the health of our patients by providing the highest quality of care for patients with pulmonary diseases, critical care illness and sleep disorders.

We have 2 convenient office locations (Lawrenceville, Duluth). We are affiliated with Gwinnett Medical Center Lawrenceville and Duluth Campus to provide Critical Care (Intensive Care Units) and inpatient services. We are on call 24 hours a day to handle emergencies.



In 2010, the ATS published Breathing in America: Diseases, Progress, and Hope, a book that explores the nature and causes of pulmonary, critical care and sleep disorders, their prevalence and burden, the benefits research has brought and the research challenges that remain. The book, which was supported by the National Heart, Lung, and Blood Institute, is written for educated laypersons and tells where we are on our path to curing or controlling 23 different respiratory conditions.
