I was feeling so down out loudly thinking about how much I suck at managing diabetes. Dr. Nicholson gave me the confidence and reassurance that I needed to hear to lift me back up. Truly the best team you have here at the Dayton location. Nurse Sarah and Dr. Nicholson are so professional and make you feel cared for as if you're their family. <3
