The office makes every effort to be helpful!

5/ 5

Dr. John Koutsoyiannis is always ready to discuss things, and answer questions without ever giving me the feeling that he’s watching the clock. The office always runs on time, never any long waits, the staff is extremely friendly and professional and the doctors are top notch. I thank Soho Smile for great care.
