Caring, Professional Dermatology Services in Tribeca

"Dr.Kahn is terrific. A rare breed of someone actually caring and interested in you and your welfare. He seems to really like what he's doing and that enables him to give quality time to his patients. The office staff in Ridgewood is abrupt and hurried and not particularly friendly, but don't let that interfere with your visiting Dr. Kahn. He's worth it."
