After graduating from UMass Amherst in June 1967, Jock began teaching in Tewksbury in September 67, where he started the wrestling program in December of that same year. Jock was also the first wrestling coach at Littleton High School (1972-73 season).

In November 1973, Jock became head wrestling coach in Tewksbury, replacing four-year head coach Denis Puleo. During Jock’s first seven years as head wrestling coach, Tewksbury was the smallest Division I program in Massachusetts high school wrestling. Jock was proud to have coached twenty-eight Sectional finalists of whom nineteen became Division 1 North Sectional champions, along with seven Division 1 State champions and two New England champions. The seven Division 1 State champions: Gary Hauswirth, Dana Rasmussen (twice), John Carroll, Steve Looney, Steve O’Keefe and Mike Keon. Dana Rasmussen, who was a two-time New England finalist, became a NE champion as a senior and went on to wrestle at UMass Amherst. David Donovan, after losing in the 1975 state finals, became a New England champion a week later, avenging his earlier loss in the state finals.

With Rasmussen capturing second, Carroll third and Looney third at the 1976 New England Tournament, the Tewksbury squad compiled enough team points for an astonishing second place finish.

In March 1976, Jock established the Mass Wrestling Federation and conducted off-season tournaments north, south, east and west in Massachusetts. Open to high school wrestlers, those tournaments took place over a period of 8 years and included 8,000 participants.

The 1977 Tewksbury team won the Division 1 North Championship, with five Sectional champions; Jock was named Coach of the Year by his peers. Two years later, four members of the 1979 Tewksbury squad earned Sectional titles.

From the spring of 1979 through the spring of 1982, Jock was president of the Mass Wrestling Coaches Association, during a challenging time when the MIAA tried to terminate seasons for all sports at the conclusion of the sectional level. This would have meant no state tournaments. Mass Wrestling Federation held their own state high school wrestling tournament at WPI and it was a resounding success. The MIAA reinstated the state tournament in wrestling the following year and ultimately all the other sports followed the lead set by wrestling.

Following his retirement from coaching in 1982, Jock became a well-known wrestling official throughout the 80’s and 90’s in Massachusetts high school and New England college wrestling. For several years, as a Lowell Holiday Tournament official, Jock mentored young officials who had recently passed the National Wrestling Officials’ Exam. In later years many of them agreed, “That Lowell Holiday Tournament was the best experience I’ve ever had, thanks to Jock.” Jock also served as head official at several sectional and state tournaments. Jock finished his illustrious career by agreeing to an impromptu request to officiate at an All-State tournament. He was called out of the stands with neither whistle nor black and whites - just a smile and guile. For three hours, Jock took the place of one of the younger officials who had been involved in an accident on his way to the tournament.

All this came after Jock suffered severe brain damage in an automobile accident, on March 5, 1966. After being unconscious for five days, followed by weeks of observation and tests, and months of rehab, doctors told Jock’s parents, “He’s like a three-year old child. He doesn’t remember yesterday or last week or anything. He doesn’t anticipate anything. He will never live a normal life. He will never go back to college. He will never have an important job. Make him comfortable and keep him happy.” However, there are always miracles and Jock’s recovery enabled him to make a variety of significant contributions in his life, including many to the wrestling community through both his coaching and officiating.

Since he retired from teaching in 2003, Jock has worked tirelessly to educate the public regarding the prevention of Traumatic Brain Injuries (TBI) in all youth and high school contact sports. Given his experiences, beginning in the spring and summer of 1966, this is a deeply personal cause for Jock. He created the National Sportsmanship Alliance; its link can be found at n-s-a.org.
