Mark Masselli is president, CEO, and founder of Community Health Center, Inc., Connecticut’s largest provider of medical, dental, and behavioral healthcare for the underserved. A Middletown, Conn. native, Masselli founded CHC in 1972 with a group of community activists. CHC currently provides team-based primary care services to more than 150,000 patients at 200 sites across Connecticut and is an innovator in the delivery of primary care to special populations. At the height of the COVID-19 pandemic, CHC was called upon by Connecticut’s executive branch to build and operate the state’s largest drive-through mass vaccination sites. Masselli led this historic effort, during which CHC administered more than 500,000 vaccines. In addition, CHC organized hundreds of mobile vaccination clinics, bringing vaccines directly into the most vulnerable communities. Masselli serves as board chair of the National Institute for Medical Assistant Advancement and of the national e-Consult provider ConferMED, is Vice President of the Goodspeed Opera House Board of Trustees, and is Chair-Elect of the Board of Directors of the national School-Based Health Alliance. In 2022, he was appointed to the State of Connecticut’s Child and Adolescent Psychiatry Working Group. He was awarded an honorary Doctorate of Humane Letters by Wesleyan University in 2009 for his work in the healthcare field.
