Allen has been a member of the MOTIV Bowling pro staff since 2012, after previously being sponsored by Ebonite.

[6] Allen has made 24 top-five finishes in PBA Tour events, and has a 7–2 record in championship matches.

[2] Allen has a high backswing and strong rev rate, but also uses a smooth slide step and release, which most closely aligns him with a power stroker delivery.

[11] On his left arm, Allen has a tattoo of the initials THB, which stands for "typical house bowler."

It is a tongue-in-cheek reply to a bowling center pro, who once told Allen he'd never succeed on anything other than league or "house" lane conditions.
