Reid F. Johnstone, M.D.

  • NPI Number:

Dr. Johnstone is a native of South Carolina and Greenville.

“I come from a large family who suffered greatly with allergies growing up. Having seen this first hand, drew my interest to allergies and asthma as a specialty.”

He prides himself and the practice on personalized and compassionate care of the individual patient. His interests include allergy and asthma care as well as evaluation of food allergies.

When Dr. Johnstone is away from the office, he enjoys time with his children and soaking in the sun on the beautiful coast of South Carolina.
