Excellent care from start to finish - front desk staff, nurse, and Doctor K.
Verified patient
It was an hour from my appointment time before seen the doctor and felt he was not really listening to me and cut my appointment short after waiting an hour over my appointment time to see him
Verified patient
100% Satisfied—Knowledgeable, Friendly Dr & Staff
Verified patient
They have sick patients wait in the car rather than in the waiting room. Dr. Koenig's office is particularly helpful with prescriptions that require authorization from the insurance company. A doctor at another practice told me I'd have to have a specialist prescribe something that Dr. Koenig prescribed with no problem.
Complete waste of time. ????
