Great first visit with Dr. Yoon! He provided honest, direct, & thorough information. I felt like he really cared & was watching out for me. I appreciated that he recommended lifestyle changes & cost effective meds that work, not just high-priced new meds on the market which is refreshing. Now, it’s just up to me to follow-through on his advice!

Dr. Yoon and his staff are professional, knowledgeable, courteous and prompt. There is never a long wait and Dr. Yoon actually sits down after every visit and talks with you and answers all of your questions. Dr. Yoon goes the extra mile and always returns calls personally. I could not have asked for a better allergist for my family.
