Dr. Karnes and his nurse were both friendly. The doctor always offers his hand for a handshake at the beginning of the appointment. It's a nice touch and creates a relaxed atmosphere. We discussed some of my treatment options for FFP and he verified that I do have Rosacea. A cyst? on my neck was removed, because it became irritated when my clothing rubbed against. All in all a very professional visit.

Dr Karnes and the staff at the Ballard center make every visit pleasant
April 17, 2026
Please pay attention to the waiting room tv. No way for guests to change the settings, and there was a gruesome alligator hunting (maybe drowning? I couldn't bear to look) program on the entire time. Reception staff were oblivious. How about just calm music instead?
