It was just a consultation for a surgery I need. It was the first time I met her. She's very easy to talk to and has me feeling less anxious about what I need done. Only reason she didn't get a 10 is due to the fact that she hasn't preformed the surgery yet. Hard to give a perfect score when I haven't been treated yet. "Bedside manor" is definitely a 10 though.

Dr. Otterson & her NP were excellent in showing & explaining results of MRI & I did not feel rushed during the appointment. I feel comfortable with them providing surgical care.
