See what patients are saying about Dr. Cassis.





Totally disrespects patients and their time. Shows up when he feels like it, you may wait 3 to 5 hours after appointment time. Office staff are rude, snotty and could care less. They will tell you" if you don't like the wait get up and leave" when you ask when Dr. Cassis might being seeing you. His equipment is antiquated. Parking is very tight and limited.
