Patient Reviews
Apr 25, 2024
Dr. Gary D. Koenig's office provided a terrible experience. Despite waiting three months for an appointment, it was scheduled for a date when I was away. The staff, particularly Michelle, were rude and unhelpful. Now, I'm being charged a no-show fee for their mistake. Avoid this office at all costs.
