Office staff is terrible. They are friendly but completely unorganized. HUGE, LONG waits. You will see the doctor for one minute. The good thing is my colonoscopy went smoothly.

Terrible why because it took me 8 months to set this all up and these girls in his office have you sitting in a waiting room for 1 hour. Who made up that rule that a patient has to ruin his whole day because a doctor wants to triple book to make money. Not me - .. Scale 1 to 10 2 GOOD LUCK
