I have been looking for someone to help with my Asthma and Allergies in Hagerstown. Always seemed a dead end. That is until I found Allergy & Asthma Center. The entire staff there go above and beyond. They are a team of caring individuals. When I first called on a Friday they were so worried about me and when I got to my appointment they remembered and were glad I was doing a little better. There was a problem with my appointment (my end) and they immediately pushed my time back an hour so I could get my daughter to work on time. So nice finding a Dr and staff who take the time to listen and help.Now getting a referral for my daughter to also be seen for her AllergiesThank you for all you do. HIGHLY RECOMMENDED4/27/2021

Clean office, courteous staff, and Dr. Yoon is great! I took my son last summer when his environmental allergies were getting bad, and I didn’t know how to manage them. After well-executed allergy testing, Dr. Yoon gave us great recommendations, and he is now doing well. I went back to the office today for myself to have testing and to get medication recommendations. I highly recommend this practice!!4/16/2021

The staff and doctor were very patient and kind. Dr. Sohn took the time to answer all my questions and fully explained my prescriptions. Two of the nurses that I interacted with, Sydney and Steffy, were very warm and welcoming. The front desk was able to efficiently and quickly schedule my upcoming appointments with a clear explanation of what to expect from my upcoming immunotherapy shot appointments. I’m glad I came here!3/20/2021
