Georgia Infectious Diseases

All of our physicians are board certified ID specialists who strive to provide you and your family members the most professional, individualized, and up to date medical care in our field of expertise. Whether a patient is ill and confined to the hospital or an out-patient seeking consultation, the physicians at Georgia Infectious Diseases, PC will work with you as part of your team of physicians to identify potential infectious causes of your symptoms and to develop a treatment plan.

In 1981, when the very first cases of HIV/AIDS were reported in the New England Journal of Medicine, Dr. Robert Capparell completed his training in Infectious Diseases at the University of Kentucky. He began to practice Infectious Diseases at both Saint Joseph's Hospital and Northside Hospital, located in Atlanta, GA that very year. He was joined by Dr. Mitchell A. Blass, a fourth generation native of Atlanta in 1999, and Georgia Infectious Diseases, PC took on its name. Rounding out our trio of physicians is our most recent associate Dr. Margaret Williamson who joined our practice in 2004. In July of 2009, after nearly three decades, Dr. Capparell retired from the practice of medicine.

While most referrals to our practice begin with a request from a primary care physician, we welcome your inquiries into our practice. If you seek consultation from one of our physicians, please either contact your primary care physician to request a consultation or if you do not have a primary care physician please download and complete our New Patient Intake Form and fax it to our office. Our office staff will contact you within 2-3 business days, however as always, if you have a medical emergency do not hesitate to dial 911.

We look forward to healing you,

Drs. Blass, Williamson and Trible
The physicians at Georgia Infectious Diseases, PC
