I think that Dr. Peters is great. She's very easy to talk to, listens to all of your concerns and doesn't rush you out of the office. I would recommend her to anyone if they were looking for that type of doctor.

I like Dr. Sarah Peterson very much. She teaches me how to work with my allergy symptoms as they change during the year, and trusts me with this information.

Becky was truly awesome. Listened to my concerns (even though I had a few of them) and worked with me to come up with a plan. She made me very comfortable and confident that my health is in good hands.
