Nov 09, 2023

Dr Frey Always explains everything so well listens to my conerns of whats going on and finds ways to help me out couldnt ask for a better doctor so glad to be her patient

Nov 03, 2023

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.

Oct 27, 2023

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

Oct 23, 2023

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

Oct 13, 2023

Dr. Frey is fabulous.

Sep 30, 2023

Dr Frey is a Great Dr and Person.

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.

Sep 01, 2023

Dr. Frey is amazing! She truly cares about her patients and it shows, she takes time to listen and find best method very glad to have found her office.

Sep 09, 2022

My appointment was supposed to be for a full work up, a full work up is not what I got. I left my appointment with more questions than when I went in. Doctor suggested multiple treatments within 15 minutes or so but the appointment felt so rushed I was not able to discuss treatments with her fully as well as the reasons why I felt the treatments I was currently on weren't working. I had waited almost 10 MONTHS for this appointment while dealing with scary symptoms. I Informed the doctor of a new diagnosis but she didn't look at my issues from that new diagnosis only my old one so I still have all the same issues that I've been battling for over a year now.

Sep 03, 2022

Doctor Frey has been great with my care from the very first visit. Doctor Frey listens to my concerns and explains things in a way I can understand. Outstanding Physician.

Aug 19, 2022

Dr. Frye was amazing! I would certainly recommend her to others who are in search of a neurologist. I'm looking forward to seeing her again at my next appointment. She did a good job at explaining what happened to me and further explaining to me how we can further figure out options for my care.

Apr 27, 2022

I cannot say enough good things about Dr. Frey, I have been a patient of hers for a long time now, and she has helped me so much!!

Apr 23, 2022

One of the best doctors I've had. Not only thorough in explanations, but also in asking me for details of my experience with my seizure issues. And most important, actually listening and answering to any and all of my questions, and providing actual thoughtful answers

Feb 26, 2022

Always professional and great communication! One Dr visit I don't mind going to

Dr. Fry was simply wonderful. She actually listened and explained things to her doctors have been unable to explain. I have been dealing with chronic pain and other health issues for over a decade, so it was nice to have some answers.

Sep 28, 2021

Dr. Frey was fantastic. She listened to me & made sure to explain everything to me. She also asked my opinion in regards to my treatment.

Jul 07, 2021

Dr Frey listens and explains very well.

Jul 03, 2021

DR. Frey is the best. Very professional and very knowledgeable. It is very obvious she cares for her patients. I have seen other Neurologists in so called Big Cities and usually feel like I am just another patient being pushed through and not being heard. Some have barely glanced up from the clipboard they have in their hands during my visit, but not DR. Frey. DR. Frey takes the time to ask you questions and ask you If you have any questions. So happy to be under her care.

Jun 23, 2021

Dr. Frey has been amazing at treating my issues. She listens to my concerns and tries to find a way to address them. I never feel like anything I say is being ignored or dismissed. I don't know where I would be now without her excellent care and support.

Jun 23, 2021

Dr. Frey is an excellent dr who is very caring

Dr. Frey always addressing issues. Follows through. Response is great. Over all wonderful.

May 21, 2021

I love Dr. Frey. I've had numerous other neurologists and she outshines them all!

Mar 31, 2021

Dr Frey and the assistant were very professional and I felt confident the care I received was very good. I was referred to MHC Institute for Neuroscience for an EMG, so Dr Frey is not my primary neurologist. The doctor and her staff were very professional and did a good and thorough job, but seemed hesitant to give advice or recommendations because they were not the primary physicians for my case. That makes sense and I am satisfied with the service s I received

Mar 26, 2021

She explained talked to us. Was very good. Had him walk to see if he was moving his legs good. Very kind & caring.

Mar 02, 2021

Dr. Margaret Frey is the best of the best! I've recommended her to anyone who needs a neurologist. From her friendliness to her concern for your best interest, she is AMAZING!

Mar 24, 2020

When I met with Dr. Frye, I made sure she understood everything that was happening to me and all of my medical concerns so I wouldn't have to make another appointment so soon or other phone calls because I don't like dealing with the office.

Sep 28, 2018

Dr. Frey and her team are stellar. They are a definite asset to Memorial Healthcare.

Sep 17, 2018

Dr. Frey takes the time to look the patient in the eye and have a real appointment instead of looking at a computer. She is fully engaged in the conversation and listens. Whether I agree or disagree, I appreciate her effort to communicate. She is not condescending and that is very important to me.

Aug 10, 2018


Aug 08, 2018

every aspect of my experience with Dr. Frey was absolutely excellent

Aug 08, 2018

My only problem with this office is scheduling and prescription call ins. When she prescribes you something it takes days before it is sent in and if you have a question for her it takes just as long if not longer to hear back. Scheduling is also far out.

Aug 07, 2018

I didn't appreciate the doctor asking so many questions about my accident prior when I was there for my routine check up and when I asked her about it she told me that she has been in enough medical insurance lawsuit claims I let her know several times I was not there for that I was here today for my routine check up that was made a year ago. Also didn't appreciate her telling me that a deer accident doesn't usually do that much damage.
