He is a very good provider who cares about his patients. I mentioned stress in my life and he asked if I needed to talk to him about it. I told him that I was seeing a counselor so we didn't need to discuss it.

Dr. Oertel is a genuine person who is easy to talk to and makes me feel confident about taking care of myself. Diabetes is an exhausting thing to deal with that you don't get a break from and he makes me feel like I'm making a difference in my own life.
