John Weller came to the Mustangs as an accomplished coach and athlete, first taking over as head coach for the 2016-17 season.
A World Rugby Introduction to Competition (Level 2) certified coach, Weller's leadership on the sidelines began with the Montreal Irish u18. He spent two years revitalizing the program to see the team become Provincial Champions in 2009. He then moved to Lakeside Academy where he assisted in the development of a formal rugby program who made the playoffs every year of his tenure.
In more recent years he has become a mainstay within London's rugby community through his involvement with London St. George's Rugby Football Club. During his time with the program, he created girl's and boy's teams that cater to athletes aged six through twelve and took on higher level coaching roles with the u16 and u18 girl's teams, while also spending a year with the u18 boys.
An IRB level two referee, in 2014 he officially joined the Mustang family as the women's rugby laws advisor before transitioning into an assistant coaching role for the following season.
