Services
Balloon Sinuplasty
Balloon sinuplasty is a minimally invasive procedure that opens blocked sinus passages using a small balloon. This FDA-approved treatment provides long-term relief for chronic sinusitis sufferers. Our specialists perform this outpatient procedure with local or general anesthesia, allowing quicker recovery compared to traditional surgery.
Allergy Testing
Our comprehensive allergy testing identifies specific allergens causing symptoms through skin prick or blood tests. We test for common airborne and food allergens to create targeted treatment plans. Results help determine immunotherapy options and environmental control measures for effective symptom management.
Septoplasty
Septoplasty corrects deviated nasal septums causing breathing difficulties and chronic sinus issues. Our surgeons reshape nasal structures to improve airflow and reduce sinus infections. The procedure addresses structural abnormalities while maintaining facial aesthetics and nasal function.

HORRIBLE! If I could give 0 stars I would. If you like sarcasm and unanswered questions then yes this office is perfect for you. Where do I even begin. Never have I ever had an experience like this at any medical center. Dr. Nguyen was rude from the start didn't even acknowledge, greet, or introduce himself. Acted as if every question or concern was insignificant. Not to mention, wait time takes forever!.Scheduling an appointment also takes for ever. Wow! ALL those years of medical school gone to the trash if you can't have proper respect and communication skills. The office was also unsanitary yuck!

Dr. Henry is the very best. I had a chronic nose problem that for many years prevented me from beating. I had a surgery with Dr. Henry, and now I can breath. I wish I had found Dr. Henry years before. It's like a miracle! Five stars are not sufficient to express my gratitude towards Dr. Henry, as well as to his staff who are very friendly and very professional. Definitely I would recommend Dr. Henry to all people who have nose problems. He's just the best! Thank you Dr. Henry!

Just got off the phone with scheduling, they don't have any doctors on staff to see patients unless you are dying (life threatening). As a patient working in health care it is important to have availability for patients no more than a couple weeks out. Either they must staff more ENT's or have a broader availability. I scheduled today 8/3 for almost December 1st. that is unbelievable. Per staff, its due to doctors not being there on a daily basis.

I hope they are able to fix the availability. Look elsewhere or a 3 month wait. I found someone in Newport who was able to get him in this Friday 8/6. I hope this issue gets fixed for the sake of better patient care.

I would like to thank Dr. Roy Deborshi and all his staff at the clinic for the great experience I had with them. Dr. Deborshi performed a sinus operation for me, I was in and out within three hours at the maximum. Also thanks to Maritza and Kelsey for the great help and assistance I needed, they were very responsive to my emails and calls, they called me after my surgery more than once to check how am I doing. I would highly recommend them. Ahmad Ammar.

I came in to see Dr. Roy and I was greeted by the friendly staff. From the moment I walked in, the staff was very responsible to ensure there was no contact with anyone infected with Covid, and based on protcal in place, they assured me all was clean and sanitized. Dr. Roy is so friendly and knowledgeable, he listened to my symptoms and asked thorough questions to get to the bottom of the problem. I felt heard and my concerns were put at ease. Thank you, Dr. Roy!
