Newton Wellesley Executive Park

Newton Wellesley Executive Park

Newton Wellesley Executive Office Park is a four-building campus located along the prominent Interstate 95/Route 128 corridor at 40, 60, 62, and 70 Walnut Street in Wellesley, Massachusetts. Originally developed between 1960 and 1989, the property features a mix of office and medical office space.

The campus has undergone a strategic repositioning from traditional office use toward medical office, leveraging its proximity—just one mile—from Newton-Wellesley Hospital. This transformation has attracted a diverse tenant roster anchored by hospital affiliates and healthcare-related users, reinforcing the park’s role as a key node in the region’s growing medical office ecosystem.
