Dr. Bonnichsen is a genuine person who cares for her patients. I was recommending her to someone just yesterday...and I will continue to do so.

I appreciated that Dr gave me samples of lotion and shampoo to try before going out to buy them. And Dr expressed concern for cost of prescription and to let her know if it was cost prohibitive to me. No Dr has ever been concerned about that before. Her kindness was greatly appreciated.

Very professional

This was my first visit with Dr. Bonnichsen, She had taken the time prior to my appointment read my medical history. I've had appointments with specialists who read my file while I was in the room with them.

The only negative was the prescription issued without initially offering a much cheaper alternative. The pharmacy offered that option and contacted the doctor to approve the change. Cost savings: $160!

The receptionist when I checked in was rude.

I would have thought that they would have looked more closely at areas effected to see if there were any additional need for treatment

I drove 600 miles round trip to get there and I will continue in the future.
August 15, 2019
both nurses and the physician were polite, professional, & very reassuring to me
