"Truly abysmal customer service... their reception staff couldn't be ruder or nastier. When I call... their response was 'PROBABLY NOT' [regarding availability]."

"I have been a patient of Dr Graig Kornreich for over 5 years. Dr Kornreich is the best ever. I went to him after seeing a few dermatologist with no results."
