What Our Patients Say

I have been through a lot because of an infection in my throat. Dr. Vandeusen had the patience to listen every and his office schedule was flexible all the time, even when I call in the last minute. He worked with me when I had concerns, and guide me to the correct decision. He removed the throat infection,and pay the same attention for me even after the surgery. The surgery went wonderful and I am feeling great now.

I have been dealing with sinus infections, polyps, and other issues for fourteen years. I began seeing Dr. Vandeusen about two years ago. His treatment has always been helpful...however...he strongly suggested a surgical procedure. I was hesitant about having the procedure. Overtime Doctor Vandeusen gained my confidence and I finally agreed to the outpatient procedure. The outcome has been better than expected. My breathing has never been better! The recovery was just as the doctor explained. I cannot detail how satisfied I am with taking Dr. Vandeusen's advice. I strongly recommend him to anyone with similar issues.

I had a Sinuplasty with Dr Van Deusen today. Kudos to him & his staff for their super approach to providing a great patient experience. His conservative approach to my condition for several months was very much appreciated & him & his staff were great during my procedure. Strongly recommend Dr Van Deusen if you need an ENT.
