Dr. Robert Lipetz

Founder, Director & Lead Physician

Dr. Robert Lipetz has always been interested in academic medicine. While in private practice, Dr. Lipetz noted that many patients in his care were in need of better treatment options to help manage chronic medical conditions. His desire to help advance medical care and improve the quality of life for his patients led Dr. Lipetz into the field of medical research. He retired from private practice in 2000 to found Encompass Clinical Research and devote himself to clinical research medicine full time. Today, Dr. Lipetz enjoys the relationships he is able to build with research study participants. He is able to give his study patients plenty of personalized attention in a relaxed setting while providing the highest quality study-related health care.
