Dr. Milstein was absolutely amazing. I was nervous going into my appointment regarding being diagnosed with Grave's Disease, and he immediately eased that anxiety. He explained everything as simple as possible and answered my questions. He was also very funny! Definitely recommend him to anyone needing an endocrinologist. It was worth the 4 hour drive!

Kelly, thanks so much for your kind review and for sharing your experience. We are grateful for the 5-star rating and for your feedback.
Chelsea and her staff are some of the most caring, connected, responsive, and genuinely wonderful people I’ve had the pleasure of working with in healthcare. They listen, communicate, follow through, and actually get things done. Prescription refills are handled quickly, messages are answered quickly, and I never feel like I’m being lost in the shuffle.
After 20 years of living with T1D, I can honestly say that I’m finally feeling like I have a team in my corner that is helping me become healthier and better understand my own health. That means more to me than I can really put into words.
I’m incredibly grateful for Chelsea and her team. They’re really good at what they do, and I feel genuinely lucky to have found them! ❤️

Kandee, thank you so much for your 5-star review. Your feedback and impressions are of the utmost importance to us.
Since being diagnosed in 2020 during Covid with Type 1 I have seen Dr. Millstein. He has helped me tremendously with teaching me all things regarding Type 1. I feel very comfortable with the office staff and they are always friendly and nice. I highly recommend Dr. Millstein.

Sarah, thanks so much for your kind review and for sharing your experience. We are grateful for the 5-star rating and for your feedback.
Was told my symptoms were not serious enough to be seen by them and they were denying my referral. Cancer runs in my family. If my primary care physician thought they were serious enough to be seen by a specialist she wouldn’t have sent a referral in the first place. My labs are all over the place and are not controlled by the medication being prescribed. I’m exhausted all the time and being told that “They need to focus on patients in more need” without even being seen or talking to a provider is ludicrous. Find a provider who’s at least willing to see you first before deciding you don’t need them.

Dr. Millstein is awesome. He has been my endocrinologist for over three years now. He's comical and very good with his patients. He placed my Eversense. It was pretty much a painless procedure. In my opinion, Vaccines and Bee stings hurt much worse. His nurse, medical assistant and front desk receptionist are sweet, caring and knowledgeable,a contributing to a good overall experience.

Tonya, wow, thank you so much for your kind review and for sharing your experience! We are truly grateful for the 5-star rating, as your feedback and impressions are very important to us.
I initially switch doctors to Dr. Millstein because my previous doctor was difficult and did not listen to my concerns. Dr Millstein has always been open to listen to my questions and concerns. He answers him thoroughly and deeply cares on what he can do to make me the most successful. I cannot say enough how much I appreciate his understanding and care!
