Quock Associates is a Boston general contracting and construction management firm that, by its own description, specializes in turning around distressed real estate into higher-visibility properties — closer to a real estate development and investment operation than a typical single-project home renovation outfit. Founded and incorporated in 2007 by owner Karl Coiscou, the company has 5 employees according to the Better Business Bureau, which rates it A+ (though it isn't a BBB-accredited business). Its Massachusetts home improvement contractor license is active with the state, and it's certified as a Minority Business Enterprise through the Massachusetts Supplier Diversity Office, active through December 2026. A 2018 Bay State Banner article on the federal HUBZone economic-development program named Coiscou as the company's owner.
