Interests  Dr. Johnson treats patients of all ages. His special interests include severe food allergies, drug allergies, bee stings, asthma, hay fever and eczema.
Additional  "Education is key. My patients deal with diseases that are directly related to the environment they live in, so it's very important for me to help them distinguish their symptoms, provide medicines that improve those symptoms, and educate them on how to use those medicines. My years of experience have really helped me know which methods work best in treating a wide range of symptoms."
