Tung has been praised for his strength at all aspects of coaching:
Tung has coached several teams to State Cup victories and WAGS Division 1 Championships. He was the key ingredient to SYC Galaxy's advancing to Regionals.

Tung became the team's primary trainer since Winter 2003 and changed the training focus to offensive tactics.
