The Staff are always kind to me. Dr Lassise we've known each other for a long time. I first met you in 1995. You have always showed me that you care about my mental healh and you always know whats best for me. Thank you all for being there for me
Dr. Lassise was great!! I went in uneasy not knowing what to expect. The appointment covered everything he needed to know, in a very short time. I had a one time appointment, but he let me know if I needed him in the future, just to call the office. Great experience!
Dr. Lassise did a nice job. He was polite, in time, and we got our visit done quickly. I was very happy.
It was great! Thank you!

A Clinic with great doctors and staff.
Very much appreciate these specialists coming to Charles City.
Thoroughly enjoy having Dr. Phil Lee as my doctor. He spends all of the time necessary to answer questions and research what could be options for me. Problem is my hearing is just getting worse and there may not be any corrections to it. He has moved me to work with Dr. Dan Lee for my hearing and Dr. Phil Lee is still handling my cpap treatment.
I was very happy with the staff and especially Dr Dettmer. He is so friendly and caring. I would recommend him to anyone needing an ENT doctor. Bob
Everybody is very friendly and curtious.
