Dr Kellogg took the time to explain my situation to me and next steps. It was clear he thoroughly reviewed notes from our last visit before we met. I greatly appreciated that since it had been a while since we last met. He really shows interest in wanting to help me.

Dr. Kellogg is brilliant and the first doctor ever to get my symptoms totally under control and then most importantly to pinpoint the cause, explain it thoroughly!



You cannot find a better allergist than Dr. Zhang. She follows up with her patients and is very thorough!
