Strong, Collaborative Leadership for a New Era of Success
A unique health care organization was created in 2019 when Summit Medical Group, one of the nation’s premier independent multispecialty medical groups, merged with CityMD, the leading urgent care provider in the greater New York area. Today, the combined company, Summit Health, is expanding access to a full spectrum of high-quality health care services in the NY/NJ metropolitan area and provide patients with a new kind of care–one that’s kinder and more connected, where every patient has access to the complete care their health deserves. Driven by a shared vision and values, the Summit Health executive team is poised to lead the organization into a new era of growth and success.
