For the second consecutive year, East Bay Surgery Center and Middlesex Endoscopy Center have been recognized by U.S. News & World Report as among the Best Ambulatory Surgery Centers in the United States. Both East Bay and Middlesex are operated and jointly owned by Constitution Surgery Alliance ("CSA").

East Bay, an AAAHC-accredited facility in Swansea, Massachusetts, was named in the Best Ophthalmology category. Middlesex, an AAAHC-accredited facility in Middletown, Connecticut, was named in the Best Colonoscopy/Endoscopy category.

U.S. News' second annual ratings offer Americans data-driven insights into their local ambulatory surgery center to inform their choices for quality outpatient surgery centers. 4,357 surgery centers nationwide across four separate specialty areas were evaluated on objective measures of their patients' care, including how successfully they avoided complications, ER visits, unplanned hospitalizations and other undesirable outcomes. U.S. News recognizes only the highest-rated surgery centers in each specialty that satisfy U.S. News' statistical assessment of performance; fewer than 17% of evaluated facilities earned a "Best" Ambulatory Surgery Centers rating for the 2025 study.

"We are incredibly proud to see our commitment to clinical quality and patient safety recognized once again in the U.S. News & World Report ASC rankings for the second consecutive year," said CSA CEO Kris Mineau. "This continued recognition highlights the dedication and hard work of our physician partners and staff, who are focused every day on delivering the best patient outcomes and experiences."

"U.S. News' second edition of the ambulatory surgery centers ratings empowers consumers to find a local outpatient facility that matches their surgical needs with exceptional outcomes," said Chelsey Wen, senior health data analyst at U.S. News. "These ratings help patients, in consultation with their doctors, choose facilities focused on quality and safety."
