We came because Daniel had been experiencing fatigue, lack of range and lack of stamina while singing. He sometimes felt hoarse while singing. Dr. Deter talked a while and asked Daniel several questions. He looked in Daniel's nose and his ears, and took care of some ear wax build up. Then he scoped Daniel's throat. He was very personable and thorough. When no growths or anything were found on the vocal chords, he suggested seeing a speech therapist to make sure Daniel was phonating in a healthy way. I was very pleased with our experience.

I had another tube put in my right ear. The procedures were described in detail before and during the time they were being performed. Dr. Dettmer and the nurse were very professional and pleasant. Great experience!

We saw Dr. Dettmer with concerns about my son's large tonsils, snoring and sleep disturbances. Dr. Dettmer hadn't seen us in a couple years but seemed to remember us, was very friendly and welcoming. He listened to my concerns, checked him out and gave us his recommendation for him. He made everything easy to understand and was very professional. He also had a great rapport with both of my children!

The doctors staff, as well as the young lady that did my hearing test ,were nice as was the doctor. I've had no improvement in symptoms but the doctor told me I may or may not. Check in was quick and seemed efficient.

Had been having bad nose bleeds and needed to have the blood vessel cauterized. Dr. Dettmer was very sympathetic during this somewhat painful procedure. I would recommend him to friends in need of an ENT.
