SPRINGFIELD — A new 90,000-square-foot community health center is coming to Springfield to provide centrally-located, comprehensive care in the Pioneer Valley.

Public and private sector officials gathered Tuesday to announce plans for the new center, a project that will eventually change the locations where area residents receive care.

“This is a terrific announcement for the Springfield community, one that will greatly benefit the Pioneer Valley for years to come,” said U.S. Rep. Richard E. Neal.

He noted that Baystate Health has long been committed to improving and expanding access to care throughout western Massachusetts. “As Dr. Keroack nears the end of his tenure, I cannot think of a better way to celebrate his achievements than with the unveiling of yet another initiative that will deliver the best results for patients throughout our region,” Neal said, referring to the pending departure of CEO Mark Keroack, who is retiring in July.

MassMutual is donating 10 acres of its 100-acre Springfield campus for the new health center, which Baystate Health plans to build, own and operate. In addition to the land, which is valued at $5 million, the large life insurance company will also provide financing. Additionally, the MassMutual Foundation is donating $5 million over five years to the project, which has an estimated total cost of $45-$50 million.

“Thanks to the generous donations and substantial support provided by MassMutual and the MassMutual Foundation, Baystate Health’s vision to create a comprehensive, integrated community health and wellness center to serve the most vulnerable populations in Greater Springfield can advance towards realization,” Keroack said in a statement.

The project is also expected to receive several state and federal grants.

As part of the project, Baystate Health plans to eventually consolidate services from four of its existing Springfield health centers to the new building. Those centers, which Baystate said are limited in size and need upgrades, are the Mason Square Neighborhood Health Center, Baystate High Street Health Center, Baystate High Street Pediatrics, and Wesson Women’s Clinic.

“We intend to co-locate four of our existing Springfield community health centers into a larger, modern facility to create this unified health care delivery wellness hub,” said Keroack. “Several convergent factors have informed our vision. The positive outcomes we have demonstrated in our Medicaid Accountable Care Organization, involving more than 50,000 of the region’s most under-served patients, have provided value to this population, improved health, and allowed us to begin to address health disparities and inequities.”

The centers serve 125,000 patient visits annually, and officials expect patient visits at the new center to hit 145,000 by 2028. The expansion of services offered by the new center is expected to alleviate the long wait times that have come with increased demand at Baystate’s other locations in the area.

Design plans have not yet been finalized, but Baystate expressed that it will seek conversations with community members and health care providers to aid in planning features such as an on-site lab, pharmacy, and space for specialty practices. Baystate also hopes to provide community spaces and “ways to bring our social service partners closer to the patients we serve,” said Keroack.

“This structure will house primary care, comprehensive women’s health, integrated behavioral health, and specialty services for newborns to those of the most advanced age,” said Dr. Paul Pirraglia, chief of Baystate Health’s Division of General Internal Medicine. “Our patients will be able to get their medications, testing, and other services all under one roof.”

The lot where the center will be built, which will be accessible at the intersection of Wilbraham Road and Alden Street, will need to be cleared of existing buildings and subdivided into its own parcel, separate from MassMutual’s headquarters. According to Keroack, the site provides ample parking, and is accessible via a Pioneer Valley Transit Authority bus route.

Construction is expected to begin in 2025 and be completed in 2027.

“Throughout our long histories in Springfield, both MassMutual and Baystate have had an enduring commitment to each other’s success as we’ve worked toward our own respective — yet similar — pursuits, helping people live better, more fulfilling lives,” said MassMutual CEO Roger Crandall.
