After 18 months of ENT, dermatology, and urgent care visits, I was referred to Dr. N. The first question I asked him was, "are you going to help me? I’m miserable!" He said. "Of course. That's why you came to me!" I liked him instantly and he was 100% right. During my first visit, he gave me enough meds to take until my next visit and a prescription that made me feel better the same night of my first visit. I have never felt better. His staff is kind, empathetic and thorough. I highly recommend Watergate Allergy and Dr. N.

I went to Dr. Nsouli last February after developing a chronic cough 1 year prior that would not go away. My primary care doctor sent me to get CT scans of the chest and sinuses which showed no abnormalities. He also sent me to an ENT specialist which scoped my nasal cavity and throat checking for signs of silent gerd and prescribed an antacid. Still no relief; so my primary next sent me to an allergist. Within 2 visits and a battery of allergy test. Dr. Nsouli identified a couple of allergies that triggered a form of asthma. He prescribed targeted medications and I am happy to say that I now feel better than I have in a long time and hopefully will be back to 100% soon.

My wife had a severe internal complication and could not eat anything other than plain rice or unseasoned white fish - everything else came back up; she lost over 30 pounds and the gastroenterologist and other doctors were stymied. Dr Nsouli examined and tested her, found her allergies and issues and gave us instructions how to remove the sources of dust, mites, etc and got her started on medications and allergy shots. Today she is back to normal and her allergy is gone. Dr Nsouli has our complete trust and confidence. He is truly a gifted physician! Thank you so much!

The absolute best! Kind, courteous staff. The very epitome of a responsive, listening, helpful practice. My allergies continue to improve - I may be able to get off the injections by November!

Dr. Nsouli, Suad Nsouli. Nadine Diliberto and their team of medical/office professionals is a class act! The doctor and nurse practitioners are good listeners - taking the time to address both straightforward and complex allergy issues.
As a patient I feel genuinely cared for and encouraged to ask questions rather than hurried along. Follow up is appropriately timed where a reasonable about of time between appointments is suggested and put in place.
The office is well-run, responsive to phone calls and extremely helpful in scheduling appointments.
