Keith Lenchner is a board-certified allergist and internist at the Atlanta Allergy and Asthma Clinic now working out of the Douglasville and Canton offices.  He lives with his wife in Midtown, Atlanta where he moved 4 years ago, after completing his allergy fellowship at Northwestern University in 2004.  Following graduation, he founded the allergy department at the Gwinnett Clinic, a multispecialty practice with 20 offices across Gwinnett County, Georgia.

Dr. Lenchner received his undergraduate degree in biology from Harvard University in 1995 and completed his medical degree at the University of Chicago in 1999.  Remaining in Chicago, he completed his internal medicine residency (1999-2002) at Northwestern before entering his allergy fellowship.

As a fellow and practicing allergist, Dr. Lenchner has published multiple papers and maintains his membership in the American Academy of Allergy, Asthma, and Immunology and Allergy, Asthma & Immunology Society of Georgia.  His personal interests include fly fishing, travel, baseball, hunting, and, most often, laughing hysterically.
