Excellent Practice and Medical Care

Highest ratings for this practice. Dr. Yoon's excellence in the field of allergies and immunology stands out in comparison to other allergy doctors that I have tried in the past. He was the only doctor that identified and addressed my specific problem. The level of relief is 100%. Many members of my family, and those I have recommended to the practice are experiencing relief after coming under his care. These comments cannot go in without mention of the excellent staff that he has assembled. Professionalism at its best is the only way to describe them. I am grateful to all of them.

I cannot express enough how much I love this place and the care we've received. My son has had asthma for several years, as well as pretty bad allergies to pollen and pets. We had a really bad experience at another allergy place in Ashburn and found these guys even closer to our house.They have been incredibly caring and responsive to Jake's needs and some of our issues that we've had with changes in jobs and insurance carriers. Super responsive when there have been prescription issues with medications. Dr. Yoon is always available when I need him and calls personally to deal with insurance issues and medication questions.Couldn't possibly be happier. Thank you for all you do!!

Excellent physician and accessible when you need him. Both of my kids see him for food and seasonal allergies. He has a great bedside manner and his staff were very attentive and kind during my son’s oral challenge. Highly recommend!

I take my son monthly to get treated by Dr. Yoon and his staff. Everyone has always been professional, courteous, and flexible. Dr. Yoon always provides us with detailed responses to any questions we may have.

We scheduled an allergy appointment for our 8 month old’s potential egg allergy. Dr. Yoon was very professional and thorough throughout the exam. His expertise and insights put us at ease. Would highly recommend his services.

The office staff at Ashburn Allergy are incredibly knowledgeable, nice and patient. The office staff has really gone above and beyond to let me know about all things related to my allergies. Dr. Yoon is very incredible and as a person who has worries about doctors, Dr. Yoon immediately dispelled that. I can't thank this office enough.

I love Dr. Yoon and his staff! They make everything as easy as possible and Dr. Yoon is incredible, attentive, and the best advocate for his patients. He always goes above and beyond to ensure you have all the answers and resources to manage the condition. I gladly drive an hour to see him as he is the best in the area!

What a wonderful kind attentive doctor! My (breastfed) newborn daughter is exhibiting classic symptoms of cow’s milk protein intolerance. I made an appointment on ZocDoc because even after eliminating soy and dairy she has had some sudden flare ups. I called to confirm the appointment and Dr. Yoon actually jumped on the phone with me for ten minutes to say the most they can really do right now is tell me to stick to the elimination diet, advising I might try dropping egg next if I think that may be an issue as well. He welcomed me to call him back anytime. I honestly don’t know any doctors that would hop on like that for a new patient because they had ten minutes and realized they might not be able to do much if I came in with my newborn at this stage (which would obviously not be easy given Covid). Will definitely look him up in the future if my kiddos develop what look like true allergies.

Dr.Yoon and his staff are wonderful and the best in the area. I came from the previous practice he was with and it is like night and day. No more long waits, rude admin and nurses, and I finally have clear explanations of my diagnosis and plan forward.

My daughter is now 5, it's been years since we found out she has food and environmental allergies, and struggled to find good doctors. It's been 2 yrs since I've taken her in to see any allergist. Although this is my daughter's first visit, the first impression should always be the best impression. I ran across Dr. Yoon's website, he was close to home and had great reviews. The reviews wasn't the only thing that won me over, it was the friendliness of the staff over the phone. They were very patient and kind over the phone. When I came into the office not only was it a quick and easy check in, but we didn't wait long. The staff and the Doctor were also phenomenal through the whole visit. Dr. Yoon really spent his time with us and didn't rush. He was very knowledgeable and informative. I am so glad I ran across their website, because this is probably the BEST experience we've had in finding a good doctor for my daughter who she wasn't afraid of :). I definitely recommend Dr. Yoon and I hope his staff never leaves him either because they're just as amazing.

Dr. Yoon and his staff are wonderful! Truly a pleasant experience :) I had to take my twin 18mo sons as they kept having reactions to food but I was not sure the specifics. He and his staff were so great with my boys and with me. Dr. Yoon was very patient and clear in his guidance and in educating me about their allergies and eczema as well as in the use of an Epi-Pen. I will continue to take my boys to him for as long as needed!

I usually don’t leave reviews but I believe this practice really deserves it! I had my appointment today and every single person I came into contact with was nice and helpful. I have had some problems with my previous allergist with getting my records but the nurses and doctors did everything they could to help me and was pleasant about doing it!Dr. Yoon I do believe really cares about his patients and wants the best for them. I felt like my previous allergist was just trying to take money from me. All Dr. Yoon wants to do is help his patients. He listens to your concerns and understands. Even though I had to wait a while because of the testing I was getting the nurses and staff were very kind and made sure I was comfortable. It made me feel like they truly cared.I am so glad to have found them! I will definitely recommended them to anyone who needs an allergist!

Dr. Yoon is an awesome doctor. He is great with kids and adults alike. He takes his time and made sure to involve me during every step of my son’s evaluation. He put my son at ease and made an anxious experience for my son comfortable.
