When Tony was younger he played ice hockey and when he started curling, he noticed a distinct lack of technical and tactical knowledge that was coached in curling compared to that of ice hockey. This really motivated him to become involved in the instruction of able bodied curling and encouraged his growth in the coaching stream of sports.
In 2003 Zummack became the Curling Director at the private and prestigious Glencoe Club in Calgary, Alberta Canada. As well as looking after the curling programs for 250 members, this position gave him the opportunity to continue his sporting education by attending the National Coaching Institute at the University of Calgary where he completed all the required tasks and courses for Level 4 coaching certification from the National Coaching Certification Program in Canada.
In 2007 he began coaching the Alberta Provincial wheelchair curling team and was able to see them win a silver medal that year at the Canadian National Championships. One athlete from that team was selected the following year for the Canadian Paralympic Curling Team that won gold at the 2010 Paralympics in Vancouver.
Tony was hired in December 2010 by sportscotland and moved to Stirling, Scotland in April 2011 to begin work with the wheelchair curling athletes and he is looking forward to the task in hand and the ultimate challenge of Sochi 2014.
