I am an elderly 83 year old who booked my appt 3 months ago. When I arrived there was no room to sit in the office with ten people jammed together in a very small waiting room size of a broom closet. I HAD TO STAND! Plus a 3 + hour wait! Would never recommend this abuse to anyone!

Spent over 30 minutes with me even though I was his last appointment. First time in my life I felt like a doctor wasn't rushing me out the door. He is a good doctor.
