Dr. Michael Cantor is one of the most experienced physician executives at the intersection of geriatric medicine, digital health, and value-based care in the United States. As Chief Medical Officer of Lifeline, he brings clinical depth and strategic insight to a platform serving aging adults and vulnerable populations through Lifeline, Medical Alert, and 100Plus.
What sets Mike apart is a combination that is genuinely rare in healthcare leadership: he is a board-certified geriatrician who has practiced medicine across nursing homes, long-term acute care, house call programs, hospitals, and ambulatory care, and still makes house calls one day a month. He is also an attorney with a JD from the University of Illinois College of Law, giving him a distinct lens on healthcare regulation, policy, and risk. And he has served as Chief Medical Officer at five different healthcare organizations, from Medicare Advantage insurers to home health companies to technology platforms serving older adults.
Mike trained in internal medicine at Beth Israel Hospital in Boston and completed his geriatrics fellowship at Harvard Medical School. He has degrees in both medicine and law from the University of Illinois, two of the most demanding professional credentials in healthcare combined into a single career.
His CMO tenure spans CareCentrix, a national home health and post-acute benefits manager; New England Quality Care Alliance, the physician network affiliated with Tufts Medical Center; Bright Health Plan, a Medicare Advantage insurer; Uber Health, where he led healthcare strategy for a transportation and logistics platform; and Intuition Robotics, where he served as the company’s first CMO and helped develop ElliQ, an AI-powered digital companion for older adults living at home. He also serves as CMO for Matrix Medical Network and Mass Advantage.
At Lifeline, Mike applies his full career arc to a mission he has pursued across every role: bringing high-quality, clinically grounded care to older adults where they live, at home.
