Jeff May - Daylight Specialists

Jeff May, President

Jeff May joined the Daylight Specialists team as President in 2019. Having the good fortune to work with some excellent companies in various industries throughout his career, Jeff finally decided to pursue his lifelong dream of owning his own business.  With a background in finance and operations, Jeff brings his experience and education into the strategy and organization of Daylight Specialists. Not having a formal background in construction himself, Jeff’s expertise is bringing an expert team together and helping them provide consistently outstanding service to our customers and achieve the best solutions possible. When he isn’t busy managing the business, he can be found playing or coaching baseball or out on a bike ride pondering what’s ahead.
