In spring of 1988 he replaced Les Dickerson as first team coach and in the 1988-89 season led the club to second place in its division.
He also led the South Wales representative (All-Star) team to back-to-back J.J. Baily Trophy wins against English leagues opposition in 1987 and 1988.
In 1997, Boulton left Arkansas to become the head coach of the Boston-based Worcester Wildfire of the USISL A-League, the forerunner of today's USL Championship.
The organization based in Hattiesburg, Mississippi has since grown from an initial three teams to a full-service Club with an Academy for both boys and girls.
The original group of committed investors were joined by Reynolds and his parents as owners and still run the club, now part of the MLS Next set-up.
Boulton acted as General Manager of the club's NPSL team, the Stars, founded in 2021 until his retirement from soccer in 2023.
Boulton's former college assistant and NAIA All-American player Carl Reynolds continues as the Academy Director and Head Coach of the Stars.
