After graduating from high school, he attended Oneonta State from 1975 to 1979, where he played as a forward on the men's soccer team.
When the Kids folded, Tozer moved outdoors to the Pennsylvania Stoners for the 1979 American Soccer League season.
In 1984, Tozer left both the Spirit and MISL when he moved to the Louisville Thunder of the American Indoor Soccer Association (AISA).
Tozer played nearly 100 games with the Thunder over three seasons, but more significantly, he was the team's head coach.
In his first two seasons with the Thunder, Tozer saw his team fall in the championship series to the Canton Invaders.
In his third season with the team, Tozer and the Thunder finally mastered the Invaders, winning their first AISA championship.
At the end of the season, he retired from playing professionally, becoming a dedicated head coach for the Attack.
Tozer guided the Wave again to a 15–5 record during the 2010–11 season tied with the Baltimore Blast for first place.
On January 29, 2012, Tozer recorded his 700th win as a coach in a 25–10 victory over the Syracuse Silver Knights.
