I find Dr. Kortykowski to be a caring and knowledgeable provider. I have worked with her for years. She treats me with respect and kindness. I don't like having diabetes, but she makes a crazy disease seem sensible, at times.

very good

This was my first visit and I was very pleased with Dr. Mary Korytkowski. She made me feel very comfortable. I will be getting results from the blood work she ordered in about one week.

i appreciate Dr. Korytkowski's genuine concern and "going to bat" for me on scheduling MRI's. She has been an incredible doctor, willing to coordinate my healthcare plan that overlaps different doctors. She is a Godsend for me and my family.

Mary goes above and beyond for my condition by preparing reports for various third parties to further my personal goals. (i.e. FAA and life insurance reports). Thank you.

Dr. Korytkowski and staff are uniformly excellent. I come away from each of my semi-annual visits knowing that I am in the hands of a caring, expert physician.

Dr. Korytkowski is by far the absolute best doctor whom I have ever had. Most recently, I was hospitalized at St. Clair Hospital for vertigo and vomiting. While I was seen by numerous specialists and had many tests done to rule out anything serious, no doctors were able to come up with a cause for these distressing symptoms. I told Dr. K yesterday, that if she cannot find the cause of my weakness and occasional vertigo, then no one can.

Waited for an hour in the exam room before the doctor met with me -very long wait was unacceptable.
