Welcome To Montclair Orthopaedic Group

To Our Patients:

We are pleased to announce that, as of July 1st 2016, we are joining Active Orthopedics and Sports Medicine (AOSM) which has offices in HackensackUMC Mountainside, as well as in Emerson and Hackensack, N.J.

AOSM is an outstanding group of musculoskeletal practitioners which includes subspecialty trained surgeons in sports medicine, total joint replacement, hand, foot & ankle and spine surgery as well as physiatrists for non-surgical spine care.

We will stop seeing patients at 200 Highland Ave, Glen Ridge as of June 24, 2016 and resume a full schedule across the street on July 1st at HackensackUMC Mountainside, 1 Bay Avenue, Montclair in 2 North Annex. Your medical records and any X-rays for services we have performed for you since 2009 will remain with us and become part of AOSM records. These items will remain, as always, available to you for follow-up visits with us or for transfer to other practitioners at your written request.

The main number for scheduling appointments with us after July 1st at HackensackUMC Mountainside is 973-680-7831. We will maintain our previous phone number, 973-746-2200, for an extended period to facilitate our availability to you and complete financial issues for your care before June 24th.

We believe that this transition will enhance our ability to provide the highest level of orthopedic care that has been our tradition at Montclair Orthopedic Group for many years.

Sincerely yours,

John F. Mendes, M.D.
