My second visit was even better than the first. What I Love? No Waiting! My Appointment time was exactly on target. and Dr Koo is just excellent -fast-professional and above all, Kind. She made sure I was comfortable throughout the procedure. Afterward, my insurance and billing information had been efficiently checked and verified by Susan, and my bill was actually less than what I thought It would be, thanks to her diligence. I couldn’t be more pleased with the whole experience. For the first time in my life , instead of dreading it, I’m looking forward to my next visit.
