I first seen her for neuropathy but my last appointment was for dementia. She mainly talked about my neuropathy very little about dementia.

Dr.Frey is the very best. I would not let anyone else do my botox shots, I could not trust anyone else to put shots in my face and neck. She has helped my migraines when no one else could.

Over the last few years I've recommended Dr. Frey to 3 family members who have become patients in her clinic.

Most definitely the best doctor I've had, all around. Never had someone more willing to actually explain, discuss, answer. Very hard to find a doctor who wants to take that time/care

Dr. Frey is woinderful

Sep 03, 2023

Dr. Frey is a fantastic Doctor. She is very attentive and caring and it shows. Prior to becoming her patient, I had been traveling to Ann Arbor, Detroit, and Grand Rapids trying to find a Neurologist I felt comfortable with but had no luck. At all of them I felt like I was just a number to them, just another patient to be shuffled in and out as quickly as possible. Dr. Frey makes me feel like I matter and it is easy to see that she truly cares about her patients. I know a few other people that see Dr. Frey and we all agree that she is an amazing Doctor and Owosso is lucky to have such a caring and knowledgeable Doctor.
