FAIRFAX — BFA-Fairfax football coach Mike Williams will take over as head coach at Champlain Valley Union next fall, BFA athletic director Geri Witalec said Wednesday.

Williams, who has been at BFA’s helm since the program was founded in 2007 and led the Bullets to their first state championship this fall, informed his players this week.

Under Williams, Fairfax has reached the Division III playoffs five of the past six years, including a first trip to the title game 2012. In putting together three straight playoff runs, the Bullets earned a 25-7 record since 2012.

An announcement of Williams’ hire from CVU is expected sometime today. He will replace Jim Provost, who announced after the past season that he was stepping down after seven seasons with the Redhawks. Williams is the second Fairfax coach to leave for the state’s larwgest school in the past three years, following boys soccer coach Katie Mack.
