Dr. Mohan Suntha, head of the University of Maryland Medical System, will replace energy company executive Calvin G. Butler Jr. as the next chair of the Greater Baltimore Committee. Suntha, who has been president and CEO of the medical system since November 2019, was named GBC board chair after a unanimous recommendation of the board’s nominating committee and a membership vote. He is the first chair elected since GBC merged last year with the Economic Alliance of Greater Baltimore.
