Kenilworth

2000 Galloping Hill Road
Kenilworth, N.J. 07033
(908) 740-4000

The 100-acre Kenilworth site is Merck's world headquarters and a main biologics research and development hub for the company. Kenilworth's R&D activities also include core chemistry and preclinical development (PCD) capabilities critical for advancing our discovery portfolio.

Merck's Kenilworth site is part of New Jersey's "Biopharmaceutical Life Sciences Cluster," a concentrated area of biotechnology, medical device, and pharmaceutical companies.

Kenilworth employees who live locally do so for many reasons: The proximity to New York City, nearby parks, open spaces, as well as accessibility to the 1-95 corridor. Northern New Jersey also offers some of the best public schools in the nation.

Employees have access to two on-site cafeterias and a credit union. Employees can take advantage of free shuttles to the Kenilworth campus from Newark Penn Station, Rahway Train Station and Roselle Park Station. Shuttle transportation between Merck sites is also available. For those who drive to work, our Kenilworth location is located directly off the Garden State Parkway.
