"I'm really excited to have it done and to be a Mustang," said the senior. "My visit with Coach Klemm went really well tonight."
Levingston had previously stated he would wait for his senior season to be over before making a decision.
The Gachos lost a few weeks ago to Crenshaw 49-14.
"Coach Klemm has been an annoyance ever since March (laughter), emailing me and making sure I call him (laughter), dude just never stops," said Levingston joking around about his decision. "But the biggest thing for me was playing time. I want to come in early and make a name for myself. I feel that SMU's offense is the best chance for me to do that. I will be able to compete right away."
Levingston joins an expanding list of California players who have now committed to SMU via offensive line coach Adrian Klemm. He had already received verbals from 4-star linebacker Devon Moreland, offensive tackle Taylor Reich, and Serra quarterback Conner Preston.
"My mom has basically adopted Devon. We talk all the time and hang out," said Levingston.
The offensive tackle chose SMU over offers from Oregon, Florida, Washington, Nevada, San Diego State, Arizona, Wyoming, New Mexico, and Bowling Green.
