• I feel my provider manages my T2D extremely well, . As a retired drug hunter, I ask a lot of questions regarding T2D & treatment thereof. I read scientific information related to T2D so many of the questions are related to recent science & medicine. I also have several chronic diseases & often am curious about T2D & them. My provider has broad knowledge of these aspects.

• This provider has helped me so much. My diabetes desperately needed to be managed and controlled when I finished chemo. The Dr. fit me in quickly for an after 5 pm virtual appointment. She prescribed meds that were so effective quickly and a CGM to help monitor my glucose all the time. When I needed to contact the Dr. afterwards, either a nurse or the Dr. got in touch and was very helpful . This appointment was my 1st in person appointment with her in a long time. She spent plenty of time with me, was so excited at my current results and always has the best bedside manner. I can't thank her enough for everything she has done to help me with getting my diabetes under control. I am so full of gratitude and appreciative.
