DevelopSpringfield CEO Jay Minkarah has resigned, taking a job at a regional planning commission in New Hampshire, according to a statement issued by the organization Wednesday. In the prepared statement, Minkarah said "It has been an honor to be a part of what is sure to be a great renaissance for the City. There are strong community partnerships working together with great projects poised for success." DevelopSpringfield formed in 2009, with a hefty donation from MassMutual toward its original pool of grant money. Minkarah was its president and CEO for five years.
