I feel very cared for and comfortable with Dr Otterburn and his staff. Went through a double mastectomy and now getting ready for small revision. I was confused about what I should do. But my trust in the Dr is complete and his advice calmed my confusion and gave me confidence in what I needed to do. Best Dr ever.

Dr. Reeves took the time to talk with me about my case and explain in detail my particular situation. She was patient, kind and attentive to any questions I had, and from my discussion with her I feel very comfortable that she has a very high level of skill and professionalism. I had my visit on video and all worked seamlessly for a good and thorough appt.
