Born on January 10th, 1997, Deo is the second child of three to his parents Rommel and Day Boongaling.

He has coached at various clubs and colleges in Northern California, starting his coaching career at his alma mater, California State university of East Bay. While there, he served as an undergraduate assistant for the pioneers in the 2019-2020 season. At East Bay, he primarily worked with the pin hitters and liberos. Through CSUEB, he met former east bay player, Leslie Ray (current Red Rock Director) where they began their friendship and professional relationship, coaching together. From 2020 to 2023, Deo coached 13s, 14s, 15s, 17s and 18s and served as an assistant director for fall and summer camps.

In the summer of 2022, Deo forged relationships with University of California Berkeley and St Mary's College of Moraga, as a summer camp coach working alongside Sam Crosson, Jennifer Dorr, Otavio Souza, Rob Browning and Albert Ahedo.

For the 2022 NCAA season, he joined the staff of the University of San Francisco, a division one program in the West Coast conference.  In 2021, the USF Dons went 0-28, and in his first year on staff in 2022, the Dons had a turnaround season finishing 14-15. They started the season off red hot, with a 7 game winning streak. From the month of October to November, USF was able to complete a 6 game winning streak with notable wins against Loyola Marymount University and a reverse sweep comeback against the #36 team in the nation at the time, Pepperdine University. While there, he primarily worked with middles and liberos, tracking stats in practices and games and collaborating on opponent's scouting reports alongside the other assistants.

In 2023, Deo joined the Penguins of Dominican University in nearby San Rafael as a coach.

Aside from coaching women's volleyball in club and college, he has also yielded success on the men's side as a coach for the Moreau Catholic men's high school volleyball program in Hayward, California. He helped the program go 23-1 in the MVAL league and finish second place in the North Coast Section Division 3 championships in back to back years.

Prior to his coaching career, Deo played varsity volleyball at St. Patricks - St. Vincents high school in Vallejo, California for 3 years (2012-2015), where he won one NCS division 4 championship and 3 TCAL league championships. He also was named 2nd team all league his junior year and during his senior year he was named team captain, 1st team all league, Team MVP and TCAL league MVP. During high school, he also played for Diablo Valley Volleyball club from 2013-2015. After his high school career, he was recruited as an outside hitter to San Diego City College where he played for the 2015-2016 season as an outside hitter and libero.

A native to the bay area, Deo grew up in Vallejo, California, attending St. Patricks- St. Vincents high school and graduated in 2015. After playing and attending San Diego City College (2015-2016) and Diablo Valley College (2016-2018), Deo transferred to and graduated from California State University of East Bay in 2021 with a bachelors in science for Kinesiology. He hopes to one day become a NCAA head coach himself and open up a club of his own after his coaching career is done.

Deo's favorite thing about coaching volleyball is the ability to empower young athletes and help them explore and grow their passion for a sport that he loves himself. Deo understands the life lessons that volleyball teaches are far more worth than just the physical and athletic skills he's able to teach. Knowing he can leave a positive impact on a young athlete's life, just as his own coaches had left on his, he tries to remind all of athletes he comes across to always have fun, continue to be curious and open to learning and to make the most of every opportunity this sport presents them.

His favorite quote is " The illusion is that the finish line is the destination, but the act in it of itself is the destination" - Phil Knight.
