Construction Updates

Scaffolding Work, Tuesday, October 25, 2022

Please be advised that scaffolding work will begin at Mount Sinai South Nassau’s 2020 Wantagh Avenue, Wantagh, site beginning October, 25, 2022.

A sidewalk shed was previously installed above the pedestrian walkway. Scaffolding installation is expected to take approximately 2-3 weeks. Interior demolition is ongoing. Exterior demolition and abatement will begin upon completion of scaffolding installation. This work is expected to be completed by December 31, 2022. Please be advised that construction fencing will temporarily be placed blocking off the area directly between 2042 and 2020 Wantagh Ave. A representative from the Design, Development & Construction team will be available during these activities and every effort will be made to minimize inconvenience during this period.

Construction to Commence, September 2022

Construction will soon commence at Mount Sinai South Nassau’s Medical Office Building at 2020 Wantagh Avenue, Wantagh. You will begin to see construction workers and equipment on site to prepare for asbestos abatement work in early-mid August. Visit here for more information and regular construction updates.

Please be advised that abatement work will begin on Tuesday, September 7 and last for approximately 7-8 weeks. Additional equipment as well as scaffolding will be on site.

The construction is expected to take approximately 18 months and will bring specialty medical services like cancer, maternity, and pediatric care directly to your neighborhood. If you have any other questions about the construction, please email info@snch.org.

Project Overview

Mount Sinai South Nassau will renovate and convert the 60,000-square foot building at 2020 Wantagh Avenue to a state-of-the-art, multi-specialty healthcare center. This Mount Sinai Doctors location will help save lives by identifying diseases early, providing an economic boost to the Wantagh area and bringing a building that has been vacant for more than five years back to life. There will be ample parking.

Mount Sinai South Nassau is investing $35 million in our community to bring you the latest in cancer care, cardiology, radiology, women’s care and endocrinology – all in one convenient location, without having to leave the South Shore.

Our singular focus is to provide residents and families of eastern Nassau with convenient and seamless access to high quality specialty healthcare services, right in their own backyard at a single location.

Mount Sinai South Nassau always strives to be sensitive to our neighbors in the community. We will provide regular updates as we move through the construction timeline.

What types of services will be offered in the building?

Mount Sinai South Nassau’s vision for this facility is to serve as a community center for state-of-the-art healthcare featuring an integrated network of specialty practices and highly skilled specialists. This community-focused delivery of multi-specialty healthcare will simplify residents’ access of the physicians that they need and elevate their overall health. Some of those proposed medical services include:

  • Cardiology
  • Digestive Disorders
  • Hematology/Oncology
  • Endocrinology
  • Radiology
  • Lab Services
  • Neurology
  • Pain Management
  • Pediatrics
  • Pulmonary
  • Surgery (non-invasive)
  • Urology
  • Women’s Health

Hours of Operation: Initially, the hours of operation for most clinical services will be between the hours of 8am and 5pm Monday-Friday. Evening hours on select days and hours on Saturdays will be phased in over time and will only be offered for select services.

Building Size and Usage: The facility will feature a patient-centered interior design, with approximately 50 comfortably furnished private patient examination and consultation rooms. This new medical office building will not include drug treatment, behavioral health services, ambulance bays or overnight hospital beds.

Parking & Traffic: Mount Sinai South Nassau has been sensitive to the needs of the local neighborhood. The site has 248 parking spots, ample parking for staff and patients, so we do not anticipate overflow parking on local streets. Efforts will be made to divert traffic off residential streets on to Sunrise Highway.

Local business owners, your friends and neighbors, share their thoughts on Mount Sinai South Nassau’s plan to bring specialty care directly to Wantagh and the surrounding area. Hear why they think the project will benefit the community.
