Says he enjoys golf because "the mental toughness needed to play this sport at a high level is unbelievable, and it requires your attention all the time. Although it may not necessarily require the most physical ability, it is by far the hardest sport I have ever played."

Grew up playing El Prado Golf Courses in Chino, California, a 36-hole facility open to the public.

Is a big fan of the Ranger's Apprentice series of books. Likes to watch American Ninja Warrior, and listens to RL Grime and Flume.

Enjoys playing chess and learned to play as a child but gave up the game for about a decade. Began playing again in January 2019 as a senior at Pepperdine, when he broke his wrist and couldn't play golf for six months, so his teammate Derek Hitchner encouraged him to start competing against him in chess. Theegala recalled, "I thought I'd beat him easily. But he destroyed me, so he kind of got me back into chess."
