I was called back early as soon as I got there. There was no wait as Dr. Koester came right in. His bedside manner is wonderful. I switched to his practice after he took care of me in the hospital I was so impressed and still am.

What else would you like to say about your experience?
Dr. Cameron Koester was absolutely wonderful! He took the time, listened to the information I had to give him, recognized and validated me as a caregiver, and treated my dad with utmost respect. My dad has expressive aphasia after a stroke and he was patient as my dad was trying to get the right words out, despite not being able to understand. Not once did we feel rushed, like he (or the rest of the staff) had to hurry up and get to the next patient. Thank you to everyone we encountered that morning.
