If you are looking for an excellent orthodontist in NYC or the metro area, look no further than Dr.Lemchen and Dr.Salzer. I found Dr.Lemchen when my parents were referred by my excellent dentist, Dr.Marc Benhuri. From my first appointment to all of my current appointments, I know that Dr. Lemchen is an excellent orthodontist. His technicians, who are young ladies of various ethnicities are friendly, gentle on your mouth, and excellent at their jobs. Dr. Lemchen is excellent at his job and warm. The office, which is situated uptown, is inviting and was recently renovated. Even though I come from Long Island to go here, it is worth the commute by car or by L.I.R.R. and the subway. To get to Dr. Lemchen's office, take the 4,5,or 6 trains to 59th St&Lexington, walk up 60th St to Park Ave and walk up the odd numbered side of the street to building # 553 which is at the southeast corner of 62nd St. Enjoy your visit here.
