Dr. Simpson and his team are top-notch. Caring, thorough, and thoughtful. I wouldn't hesitate to recommend.

Dr Simpson takes time for each patient and is very thorough. The nurses are very friendly and informative as well.
My daughter has been receiving allergy shots with Dr Simpson’s office for almost 4 years now. We couldn’t be happier with the results!

I have been seeing Doctor Simpson since 2006 and I just can’t say enough about him and his stuff!! Warm welcoming and very professional. I have never seen any doctor taking their time to listen or explain to their patients. I’m very impressed!! Asthma and allergies are very well controlled with Dr. Simpson’s treatment.

I have been going to the Falls Church location for about a year now for allergy shots, and Dr. Simpson and all the nursing staff are courteous, friendly and highly skilled. Kisha at the front desk is always friendly and willing to help! Getting allergy shots can be a time commitment, but the whole office works together to ensure that patients are in and out quickly without feeling rushed, which I really appreciate!

Very professional and experienced. I've always felt I was getting the best treatment for my allergies as possible. The nurses and front desk are great to work with and they handle all of the insurance issues that may come up quickly. I've gone to both locations (Falls Church and Alexandria); I prefer the Falls Church location because the waiting area seats are more comfortable and there's wifi. It's important if you have to be monitored after taking allergy shots.
