Steward Health Care and Nashoba Valley Medical Center Announce Appointment of New System-wide Chief Medical Officer Joseph Weinstein, MD

New chief medical officer brings decades of patient-centered experience to leadership role

The Steward Health Care System and Nashoba Valley Medical Center recently announced Joseph Weinstein, MD, as Steward’s new system-wide chief medical officer. 

Dr. Weinstein, a cardiologist, has been a practicing physician for nearly three decades. Steward’s first Chief Medical Officer Justine Carr recently retired, leaving a legacy of improvements at Nashoba Valley Medical Center that have benefitted Ayer area residents. Dr. Weinstein expressed his commitment to continuing this progress.

“During her tenure, Dr. Carr helped Nashoba Valley Medical Center achieve the highest caliber of health care and I am honored to follow in her footsteps by continuing this work for the community,” said Dr. Weinstein. “I look forward to building upon her exceptional track record by continuing to strengthen the exceptional patient care and patient services currently available at Nashoba.”

As the chief medical officer overseeing all medical practices, Dr. Weinstein will be focused on ensuring best-in-class outcomes and experiences for patients, improving behavioral health access and quality, and leveraging technology to better serve patients and the community.

Previously, Dr. Weinstein has served as the chairman of Internal Medicine and as vice president of Medical Affairs at Good Samaritan Medical Center. He was the vice president of Medical Affairs at Carney Hospital in 2015 and 2016.

“My vision for the future of high-quality health care at Nashoba Valley Medical Center is informed by the perspective I have developed over my thirty years of experience with patients,” said Dr. Weinstein. “I am excited to bring help, ensure a bright future and quality care for patients across the Steward Health Care System, including at Nashoba.”

“We are thrilled by the appointment of Dr. Weinstein as system-wide chief medical officer,” said Salvatore Perla, president of Nashoba Valley Medical Center. “Dr. Weinstein is an exceptional choice and patients will benefit greatly from his contributions both locally and across the entire Steward system.”

“I am looking forward to working with Dr. Weinstein in this role as the system-wide chief medical Officer for Steward,” said Christine Basil, RN, MSN, Vice President/CNO of Nashoba Valley Medical Center. “We’ve made great strides in recent years and we know that will continue to do so with his leadership.”

With coordinated care along the entire continuum and a multidisciplinary, team-based approach to providing health care, Steward has come to be a leading innovator and provider network in New England.
