Geoff Hennessy began his coaching career as one of the original staff of QTC in 1974. He took over the reigns as director at the age of 19 with the untimely death of club founder Frank Kelly in 1976. The club maintained a membership of over 400 kids and established itself as a feeder system for local high schools and colleges under Geoff's guidance.

He began his scholastic coaching in 1976 at Sterling Jr. High. With stops at Atlantic Middle School and a two year stint at North Quincy, he joined the staff at U-Mass Boston helping lead the Beacons to four NCAA division 3 Championships while coaching 20 All-Americans. He returned to North Quincy High in the fall of 1988 and continues to lead the Red Raiders to league titles and other accolades.

A 1974 graduate of North Quincy High, Hennessey was named "first captain" by legendary coach Lou Tozzi. With 13 Boston Marathons under his belt and a personal best of 3:07, his athletic accomplishments have spoken for themselves. He holds a bachelors in Psychology from U-Mass Boston and a masters in Exercise Physiology. A Masters level track official and a member of the Mass Track & Field Officials Association, Geoff is Level I certified for coaching by the USATF.

Coach Hennessey also edits the newsletter for the Mass State Coaches Association and is on their executive board. Geoff is employed as Mental Health Councilor at the Westwood Lodge. He resides in Wollaston with his wife Margie and daughters Suzanne and Rebecca.
