Read what our patients have to say about the diabetes and endocrine doctors at Grunberger Diabetes & Endocrinology

  • I write this note with humility, gratitude, and joy. Humility, as a result of watching the Tobin Team listen to problems intently before developing solutions; gratefulness, in putting to use their experience, expertise, and lessons of science to create what I would call “a miracle”. The end result so far has been of joy. I am deeply grateful to the Team and include my strongest possible recommendation.

    Dr. Amy Tobin is my husband's endocrinologist at this practice. I cannot say enough good things about her. She is caring and thorough and so knowledgeable. The staff here, like many practices, are very busy, but they have never been rude to me whenever we have called with prescription and refill issues. The location of this practice is not practical for us, but it is well worth the long drive.

    The receptionist was very helpful in kindly and gracefully leading me through the registration process. She was interacting with a number of clients calling for her attention and help. Yet, she carefully and warmly facilitated each of our registrations and expressed care for us. Amy is a delightful care provider as well. She is conversational, is technically competent in explaining test and scan results, and easily recognized my immediate needs and addressed them. She expressed empathy, a warm regard for my well-being, and gained my trust and confidence in her. Dr. Jon M. Huegli

    I really appreciate the practice. They don't judge you or expect you to follow or do something your not comfortable with. They make suggestions and alternatives to what ever your need is. Donna is so easy to talk to and very ❤. Also a shout out for Angie at the front desk. She's another caring lady. She will go out of her way to do whatever she can to help or fix a problem. Very kind and caring too. Thankyou Grunberger diabetes institute ..GDI

  • It has been my experience, for more than 10 years of care, that the entire staff at GDI has been informed, supportive, and thorough with their treatment as I deal with type 1 diabetes. I am confident that I am getting the most up-to-date information about technology and services available to manage my health. Thank you Dr. G, Dr. Hamill and GDI staff!
