BURLINGTON — Sarah Carpenter, executive director of the Vermont Housing and Finance Agency, will be retiring after 20 years at the agency’s helm. “As a result of Sarah’s vision and skill, thousands of Vermonters have moved into decent, affordable homes since she arrived at VHFA in 1998,” said Randy Amis, chair of VHFA’s board of commissioners. “She has expertly led VHFA’s financial activities and programs, built strong partnerships and shared her deep expertise with state and federal policy makers. Vermont is a better place to live thanks to Sarah’s impact.” Carpenter is a native of Burlington and a graduate of the University of Vermont and Harvard University. Prior to VHFA, she served as executive director of Cathedral Square Corp. from 1983-1998.
