I usually rate a facility with the number of stars and no written review but this Center is absolutely the best. I’ve had procedures done there over several years and I wouldn’t go to any other facility if I could avoid it. The staff is A+ Everyone is courteous, respectful and professional. There is very little if any “wait time.” All details of the procedure(s) are carefully explained and all questions answered. On my last visit, I was most impressed with the anesthesiologist who was extremely reassuring after I explained my fear of being put to sleep. Of course Dr. Postic is the very best. Every effort is made to make you comfortable and after procedure requirements are explained in recovery. The follow up phone call the next day to check with you is always appreciated. I can’t provide enough positive statements about this center.
