Verified Patient Reviews
I was very impressed with how personal and professional Dr. Nsouli and his nurse Sandy were. I felt cared for. I was impressed with their knowledge, ability to get to the bottom of the problem, provision of materials for relief and education, recommendations for immediate relief and analysis of my problems. Very thorough and excellent.
Dr. Nsouli was incredibly knowledgable and friendly. His staff were very professional as well.
Dr. Nsouli was amazing! So professional and courteous.
Dr. Nsouli and his staff took time to explain every step of the process, which made my visit enjoyable! They were lite-hearty and professional throughout my visit.
His office is very busy, and I wasn't called back for about 30 minutes. But I felt very comfortable with Dr. Nsouli and got the feeling he was listening and absorbing what I said. The nurse practitioner working with him was also great, as were the nurses and front desk staff. Dr. Nsouli explained everything well and seemed very up-to-date on current research and developments in his field.
Wonderful doc and staff! Highly recommended.
This was my first visit and it went very well. Dr. Nsouli has wonderful bedside manner, backs up everything he is saying with clinical studies, and reassures you that he is going to make you feel better. I would recommend him in a heartbeat.
Such a great experience!
I have been to so many physicians in the past 8 months for some difficult to dx, and odd symptoms. Some of the practitioners I have seen made me never want to go back again due to how they treated me! I, an RN for over 20 years, developed a phobia of going to the doctors! What a relief when I met Dr. Nsouli. I could breathe out. He was professional and kind. He listened to me, answered my questions and explained things to me. I absolutely appreciated my appointment with him. Highly recommend.
Extremely thorough and knowledgeable. Was very patient with questions.
He seemed focused on analyzing and solving the allergies. He was reassuring and kind. I left with a treatment plan and some insight into my allergy and sinus issues.
Really thoughtful doctor, great listener and extremely intelligent.
It was one of the best doctor's visits in a long time. I wasn't rushed through the appointment, he and his staff were very professional, and he displayed an expert level of knowledge.
Dr. Nsouli was so knowledgeable but still took the time to engage with me as a new patient (with a long history of miscellaneous symptoms). I really appreciated how personable he was even with his extensive training (since that is sadly not always the case) and how he really made a point of connecting with me at a personal level while talking through my initial treatment plan.
Everyone was very knowledgeable and explained things well. Made me feel very comfortable.
Very helpful and informative about my allergies.
i was so impressed with the whole experience. From making the appointment on line, follow up reminders prior to the appointment thur the time I left the office. The office staff is delightfull and efficient. The nurse who did the inital meeting with me, BP, etc. was wonderful. Dr. Nsouli was such a gentleman, so professional, and I knew he was genuinely interested in my clinical story and explained everything clearly I left with a very clear understanding of my evaluation, and what the plan of care was going to be. Dr. Nsouli and his staff are without a doubt THE BEST!
Dr. Nsouli is the best of the best!
Dr. Nsouli was very professional and easy to talk to. Very knowledgeable. I left the office with confidence that I was given the best treatment.
Amazing! Wonderful office staff and Dr. Nsouli is incredible. Dr. Nsouli is compassionate, attentive and very through.
I felt like Dr. Nsouli cared about my problems and found solutions to fix them. Very efficient as well as his staff. I hate allergy testing but at least this was quick and painless.
Amazing practice great staff and wonderful doctor... highly recommend him it was my first visit and I already feel relieved after seeing him.
He was patient with my concerns, very friendly, and suggested many solutions to my health issues. Highly recommend!
Dr. Nsouli is an incredible doctor. Very excited that I found him and I am very excited to be one of his patients. Also a trusted doctor of the White House.. speaks volumes about his work. I was amazed by Dr. Nsouli's thoroughness and how he took a genuine interest in finding the root of the issue and explaining the future course of action accurately and concisely.
Dr Nsouli was extremely thorough, pleasant and professional. He made me feel very comfortable throughout the visit and answered all my questions. Even while sitting in his office full of signed photos from of former, current and future presidents and their staff, I felt that he was personally attentive and interested in helping me figure out my allergy challenges.
This was the second Allergist I have visited since I was first tested for allergies back in 2001. I had an awesome experience and the doctor is really cool and professional!
I enjoyed my visit with Dr. Nsouli - he was literally one of the first doctors EVER to help get my skin under control and to help with my sinus issues. I'd definitely recommend him!
Iwas really impressed by Dr. Nsouli. He's very attentive, extremely knowledgeable, listens to patient's concerns and addresses all of them without rushing patients like other doctors do. His practice is very busy...we had appointment in beginning of August and the waiting room in Burke office was full so be prepared to spend some time if quality of care matters to you. Despite all his credentials, Dr. Nsouli is very down to earth and humble person, very warm and approchable personality. I liked his way of interaction with my teenage daughter. He is not a type of doctor who orders a series of unnecessary tests just to pocket money. Instead, he selects and pinpoints only those that truly needed and recommends effective OTC medications. I was really impressed and will definitely be back for my daughter's allergies. Highly recommend! In fact, from the moment we entered the doors of his office, all we experienced is the kindness and warmth of his staff.
I went to the Burke office for my first appointment. It was very easy to find and all of the staff are very friendly, professional and prompt. Dr. Nsouli's credentials are incredibly impressive. He was concerned with my issues, took the time to listen to my concerns, answered all of my questions and explained everything in detail. I highly recommend Dr. Nsouli and his staff!
Excellent Doctor and professional staff! Got appointment in less than a week, and he quickly got to the heart of my problem.
It was amazing! Prompt, efficient, knowledgeable. Lovely office and polite staff. For my appointment I was treated as though I WAS THE ONLY PATIENT ON THE PLANET; no rushing, complete explanations and thorough evaluation with a "bedside" manner to die for. All in about an hour !!! But wait ... he takes insurance!!!! Don't know if I want to cry or do the happy dance over my good fortune to find him. I think I will do a bit of both. Since when has a doctors visit made your day??? This made my week. This guy is a grade D diamond, no inclusions. So rare - PRICELESS!!!!
Dr. Nsouli was very thorough with my daughter and explained everything well. He was receptive when I asked questions.
He is extremely professional and friendly, as were his staff. I was a new patient and had made a morning appointment on Zocdoc only the night before. Nonetheless, I was treated as though I had been one of his life-long patients. I read some reviews which portrayed him as arrogant, etc...And I was worried and skeptical when I went in, but I did not have this experience at all. I was treated with respect and great care. He is confident, efficient, and a true expert professional.--as he should be. I was extremely impressed and will continue to go to him. I will update my review as treatment continues.
One of the best, caring and knowledgeable doctors I have ever seen. The best part he CARES , oh I mentioned that already. His work was thorough and I felt better walking out the office as I couldn't breathe thru my nose coming in the office. Btw this is my fist time writing a review on any doctor. That's how much I think he is the best Allergist ever.
Honestly, not sure if i should give one star or two. I'm still waiting for more than an hour for a simple follow up. No explanations, no aplogies. At the 1.5 hour mark i will have to walk out
He spent a good amount of time with me reviewing my medical history and the results of my allergy testing. I was very impressed.
Great professional, loved the service.
I recently moved down from Baltimore to DC and about died from my allergies and knew I needed to seek out an allergist for help. Dr. Nsouli was very knowledgable and personable, and I appreciated the time he took to assess my individual allergy symptoms and come up with a treatment plan for me. He is very thorough, and I feel very confident in the outcome of my appointment. Highly recommend Dr. Nsouli for anyone in need of an allergist!
From the warm greeting I received from his staff, to his thorough and thoughtful exam, I had an excellent professional visit with Dr. Nsouli. And after several attempts with various fine DC doctors, I believe he understands and will be able to treat my problem.
He is extremely knowledgeable and careful with patients. Excelent doctor!!
Dr. N was extremely friendly, patient, and intelligent. He listened very carefully to my issue and immediately provided sensible, clear diagnosis and feedback. What a refreshing doctor visit - can't recommend enough.
Dr. Nsouli listened to me. He was thoughtful about his tests and treatments and I knew this because he talked to me and gave good explanations throughout the appointment. He was respectful of my time as well. The entire office and visit was very well organized and the whole staff was friendly and welcoming. The best doctor visit I've had in quite some time!
He was a very educated man and tried to explain everything so I would understand my condition. He had very good people skills as well. I would definitely go back to him again.
Dr. Nsouli is very personable, instructive, and open and responsive to questions about personal health and allergy stats overall. Thank you!
He was awesome.
Dr Nsouli was great. We brought our 21 month old little girl to see him. We feel lucky to have been referred to him!
I left Dr. Nsouli's office feeling confident I was in the right hands. In spite of being very busy with other patients, he was thorough and very interested in resolving my problems.
Excellent credentials and service. Receptionist was warm and examination was thorough.
What a pleasant experience. From the front desk to the medical staff are very professional and provide great patient care. Dr Nsouli is a brilliant and dedicated doctor. During my visit, Dr Nsouli went above and beyond to accommodate to all my medical needs. I’m very content and looking forward to seeing him my next visit.
Dr. Nsouli was professional and very knowledgable. Answered all questions with ease. Friendly and helpful staff walked me through the testing done in office and use of all of my prescribed medications.
Very comfortable with the Doctor and his knowledge. I feel confident that I will feel better.
He listened to me. Was detail oriented. Discussed my medical concerns
Excellent. He's thorough and fast. He's interested in getting you the services you need, but he doesn't seem to want to chat about your personal life for 30 minutes. Absolutely fantastic, especially for a working professional who doesn't have a lot of time.
The doctor was extremely knowledgeable. The entire team from reception, to nurse, to doctor, to checkout was the most well synced and efficient I have experienced.
Great experience! The staff was extremely friendly and thorough. Dr. Nsouli welcomed and answered all my questions and I'm confident I received accurate and actionable information.

First appointment and I was impressed. Very thorough. Talked through everything. Made recommendations on the spot.
Dr. Nsouli has a great bedside manner and he is very thorough!
I have had one visit only. Everyone at the office was very friendly and professional. After filling the paperwork, I was called in pretty quickly. The doctor was very friendly and professional. He quickly gained my confidence. This was my first visit for allergy consultation and the allergy tests. I have been given prescriptions and have a followup visit in a month. I will know by then how the treatment is working. Based on my one visit, I would recommend Dr.Nsouli
The visit with Dr. Nsouli was both educating and enlightening. He showed me my problem and tended to all of my complaints in one visit and prescribed medications for all of my complaints as well. A good doctor to say the least!!
Excellent. Highly professional. Patient. Incredibly helpful. Highly recommend.
Wonderful! He and his staff were attentive and informative. I felt like I had finally found doctor who understood my life long problems and had a comprehensive plan to resolve them.
It was a good one. I was treated professionaly.
Dr. Nsouli is a leader in his field. If you suffer from allergies, then Dr. Nsouli is the doctor to go to.
We are super pleased. He gave us very good advice, and we have full confidence that he can help us.
Dr. Nsouli was awesome! I have been to other allergists but he is definitely the one I will be going to from now on. The office staff and the nurses were all wonderful and were a huge help. He listened to my concerns and addressed them. He also made sure I was completely comfortable before leaving the office.
I am so pleased with my experience at Dr. Nsouli's office. Dr. Nsouli spent a great deal of time diagnosing my issue and making sure I had the proper follow-up care and referrals. He took the time to explain everything in an understandable fashion. I have been to many doctors for this issue and this is the first doctor that was able to actually help me- what a relief! Highly recommended.
Outstanding doctor. Took an exceptional amount of interest in helping figure out what was wrong, explained everything carefully and made sure I understood.
He was great!
Him and all his teams are very piloting and very pleasant. This was my first visit but I feel like I've been there before. They all makes me very comfortable. Thank you.
I just loved Dr. Nsouli! I was early but they saw me even before I could complete all my new patient paperwork. The nurse was very friendly and explained everything. And Dr. Nsouli really seemed to care about me... and took his time with me. I'm really glad I found him.
I've been his patient for several years.
It was a first visit and I am looking forward to feeling much better and believe that it can happen unlike other doctors I have seen. The staff and doctor we all very nice and helpful.
Dr. Nsouli was very thorough and gave me a lot of his time. I absolutely recommend him.
Brilliant doctor! Extremely knowledgeable and helps explain things at a patient-friendly level. You can tell he cares :)
My visit with Dr. Nsouli was the best allergy appointment I've had. I've suffered from allergies for years and have neglected treatment in the past. He was non judgmental about my neglect and created a treatment plan for me that has helped me immensely. I highly recommend to anyone. The staff at the Watergate office are super helpful and friendly that visiting the office is always a pleasure.
Dr Talal Nsouli he is very excellent and I highly recommend , my appointment was really fantastic .
He was absolutely wonderful and thoughtful
Dr. Nsouli was friendly, gave me his full attention, thoroughly answered my questions and explained everything he did in detail. One of the most pleasant trips to the doctor I have ever had! I was extremely impressed with Dr. Nsouli and his staff.
Dr. Nsouli and his staff were very professional and pleasant! I will definitely be back.
He cancelled a couple of days before my appointment. Which was really annoying because I was so excited I actually found an allergist appointment that fit my schedule. I couldn't find another appointment to work with my teaching schedule so I just ended up having hives on my wedding day!
This was my first visit. The wait was inordinately long - over an hour. The staff eventually recognized the delay and was in the process of rescheduling my visit with apologies when it was decided that someone could see me. Nonetheless, my entire visit took close to two hours and most of that was sitting around waiting to be seen. Dr. Nsouli is obviously a very busy man and while nice, his bedside manner demonstrates that. Very business like. His staff is welcoming, warm, and very efficient as well. I appreciated the folder of information provided to me as it contained some articles regarding my condition that gave me insight into my condition as well as ways to improve it. An excellent way to educate your patient and save time!
I've been meaning to write this for quite a while. I had hope, because of his credentials, and thought that maybe this doctor is really good at what he does. However, I learned something else. If you would like to see a doctor who doesn't listen to his patients, and who is Big Pharma's best friend with dollar signs in his eyes, this is your guy. I was a healthy thirty something year old, and had an adverse reaction to a drug that this doctor loves to prescribe - Levaquin (was not prescribed by him). I developed severe allergies that I never had before this medication. I described my side effects and experience after taking this fluoroquinolone antibiotic, which are riskier than most doctors and pharmacists know and allow you to believe. He looked at me like I had three heads and talked about how it is all in my head, and threw arrogant doctor knowledge at me about how there are people who are allergic to water (how is that appropriate?) No empathy, does not listen to what you are saying, horrible bedside manner…he just wants to prescribe you a bunch of medications without really considering your situation.
He is very professional, dignified, intelligent and thorough. His staff are professional and the medical assistant was great/
Friendly staff, and Dr. Nsouli is extremely thorough and kind. He explained all tests and treatments clearly, and I felt like his focus was on getting me better the entire time. Never felt rushed. There is someone on call 24/7, which is also a plus. Highly recommend...going to book an appointment for my husband right now!
Please note thewait time was because I mixed up my appointment date and came a day early. They were kind and accomodating and saw me anyway. It was less than a 15 minute wait to be seen. EXCELLENT!!!
Very competent and friendly doctor. Unfortunately he was stuck in traffic so it took much longer than expected, but the actual tests were very quick and painless!
I have great respect and appreciation for Dr. Nsouli's knowledge! I have been going to him for my allergies and asthma for over 12 years.
He's a great asthma expert who uses humor to convince you to take care of yourself. Today he knew exactly what I needed after a serious asthma episode last week which was still causing me wheezing and blocked breathing. He got right to work and gave me nebulizer treatment there in his office. I went home with my own nebulizer and treatment plan to keep me on the mend and out of the ER. He is absolutely the best doctor and asthma expert I have ever experienced in 20+ years of living as an adult with asthma.
wait time was long. treatment turns out to be a waste of time. Very expensive if you have deductibles. Not recommend.
Dr. Nsouli is very up to date and knowledgeable, not only about allergies and immunology, but also dermatology. I've been struggling for 5+ years to get symptomatic relief and to have a better explanation of why I was getting those symptoms. I have atopic and seborrheic dermatitis, which my dermatologist was blindly treating with oral prednisone after the highest potency ointments stopped providing relief. Dr. Nsouli explained the rebound effect that leads to the worsening of atopic dermatitis from oral prednisone use. He prescribed specific medications to treat my symptoms and covered all bases, including my low vitamin D and the underlying staph infection I had due to constant itching from atopic dermatitis. I'm only 3 days into my treatment and my facial/neck rash and edema has significantly decreased and I just generally feel better all-around. I couldn't be any more happier with the care I received.
Dr. Nsouli and staff were professional, caring, and timely!!
I was impressed with the whole office
Very professional, kind, and passionate.
Dr. Nsouli was great! He took the time to go through my history and ask me about my concerns. I'd definitely recommend seeing him for your allergy needs.
He is an absolutely first rate allergist. He is scrupulously thorough and caring with his patients, and is a leader in research in his field in addition to a practitioner. Could not recommend him more!
He is a wonderful and thorough doctor. I highly recommend him. Though we haven't gotten to the bottom of my problem yet, I feel confident that he will continue to follow up with me and try things until I am better.
Very thorough, good explanations of the day's tests and upcoming tests and possibilities for dealing with my health condition. All staff I dealt with were very professional, also with great bedside manner. Didn't feel rushed at all, had plenty of time to ask questions. Procedures were clearly described. A great visit!
Wonderful staff and Dr. Nsouli was very professional and kind. Made sure that I understood everything we discussed.
Highly communicative focuses on educating the patient. Responsive
I recommend Dr. Nsouli to anyone with a child who suffers from allergies. He spent an hour with us, explained things clearly, gave us excellent feedback and worked seamlessly with his warm staff. I went put of network to see him and have zero regrets.
Excellent! Very cordial and polite. Took the time to properly explain me my condition, the prescriptions he gave me, as well as the tests. Great staff as well.
great. super professional, well-oiled system. Everyone very friendly and Nsouli is really warm and generous with his time. A word of caution...this office is SUPER busy so prepare to wait. Lots of people want to see him.
We haven't come up with a solution yet, so I can't really make a proper judgement. This is a work in progress.
It was very good, he clarified for me a lot of thing about allergies , I highly recommend him for any person has problem with allergies
He was not only extremely knowledgeable but was nice, funny and very good at explaining my allergies and treatment. He's definitely my favorite doctor.

He was thorough and very good. He got to the bottom of my issue quickly and was able to help right away..
He is truly the best of the best!!!! Awesome staff. Very thorough. A++++++++
I am so thankful that he was available at the Burke office to see my daughter. And I was able to get an appointment within a week - which is rare with a specialist. He is wonderful, and I am completely confident that his diagnosis and prescribed treatment will relieve my daughter's allergic reaction.
Great place and friendly staff. I confused my day of appointment and they still accommodated me.
Exactly what I thought. Very professional!!!
He was very thorough. I will recommend him to friends and coworkers.
best doctor experience
As always, a fine, professional experience.
Very professional and knows what hes talking about... definitely recommended!
Just a true breath of fresh air-a Dr AND staff that knows how to treat a patient with courtesy and respect!
Very detailed appt. Stressed open communication and to call with any and all questions. I felt all of our concerns were addressed.
A great doctor.
Brilliant, thoughtful, great doctor.
Very personable and knowledgeable using cutting edge techniques to diagnosis my symptoms. I objected to having my photo being taken for my medical file. I gave them my drivers license for them to photo copy which should suffice.
A very good overall experience with a doctor that listened and provided good adive.
Always a pleasure to see Dr. Nsouli.
Dr. Nsouli is very smart and explains things in an easy to understand manner. I am a pharmacist and his explanations of how to use inhalers and nasal sprays were the best I've seen of any healthcare provider.
He was extremely personable and friendly. He was thorough with ALL of my concerns. I will be bringing my entire family to Dr. Nsouli!
Doctor Nsouli was very thorough. His staff was very helpful. I was caught in traffic and was a few minutes late, but they were friendly and able to still see me in a timely manner.
Dr. Nsouli was wonderful. Very thorough, answered all my questions, explained the process every step of the way and didn't make me feel rushed. (HUGE pet peeve--Dr's shouldn't take on so many patients if they can't give them proper attention.)
Wonderful! The staff was so friendly and very kind. They made sure my discomfort level stayed on a minimum level and I felt they were truly concerned about my condition. I was definitely Mariana and not the 10:30am appointment.
As always, his staff and he are always very detailed and professional.
It was fantastic! I really felt like i was being taken care of.
I've known Dr. Nsouli for years; he has treated my children and me. He is always right on the mark and knows how to deal with our issues.
Dr. Nsouli was very thorough, professional and friendly.

Thorough and efficient service, very professional without being cold.
It was a pleasant visit. Dr. Nsouli's records clearly prove his credential.
very thorough, quick and answered questions
Dr. Nsouli was kind, helpful and efficient. He seemed pleased that they would be able to help me with my allergies and that I would start feeling better, which was nice. Everyone who worked in the office was nice and helpful.
Dr. Nsouli is incredibly competent, friendly, and accomplished. His staff is also very pleasant and knowledgeable. I was very satisfied with my visit.
Very professional! Left no stone unturned! He discovered I had a sinus infection which my general doctor didn't find!
The very best.
Very thorough and thougful. He really listened to my child's symptoms. Everything went smoothly. He gave a child a gift after the skin rast test! Thanks again!
Dr. Nsouli was diligent in his query into my specific health problems. The fact that he was caring, courteous and professional was just an added bonus. 15 minutes into the consultation, I knew I was in good hands. I highly recommend him to anyone with allergy/asthmatic concerns.
Fantastic service from the whole staff. Great people, great care.
He is very thorough. His staff are already very pleasant.
It is very clear that Dr. Nsouli is an expert on allergies. Combine that with his kind demeanor and you can't ask for much more for a trip to the doctor's.
The staff and Dr Nsouli were very friendly and made me feel like I was being listened to and my concerns were being addressed. Based on my first visit to his office I would definitely recommend Dr. Nsouli.
Very nice and knowledgable
