Attended La Jolla Country Day School.
Took guitar lessons from former Eagles guitarist Don Felder.
Says he gave up acting in the late 1990's because he was usually type casted as a high school kid. He was in his early to mid twenties when he was on Boy Meets World.
Remains good friends with Salute Your Shorts co-star Danny Cooksey and provided background vocals to Cooksey's band Bad4Good "Refugee" album.
Don Felder gave him a guitar that he played on the Eagles "Long Run Album" to him as a birthday present.
He was in a band called "Sheriff" with Salute Your Shorts castmates Danny Cooksey and Michael Bower.
While his character Ronnie Pinsky on Salute Your Shorts is jovial and charismatic, Sennett says he's more introverted and reserved.
There were plans to film a third season of Salute Your Shorts but he told Steve Slavkin that he would not return for season 3. Ironically enough there was no third season since Slavkin refused to move to the cast to Orlando to be filmed on a soundstage in front of a live studio audience.
