Reviews
Positive very information and helpful feed back while addressing my concerns.
Dr Frese has been my Dr for years. As always, on this latest visit, I found him to be attentive, thorough, giving me clear answers to my questions, unrushed.
Wouldn't go anywhere else. Thorough, Informative and on top of everything. Have been with Dr. Frese for many years. Highly recommend
