Unlike most coaches, Trillo did not play professionally at first. He was out of the bird’s nest quite early when he first got the offer to coach for a private school for boys called Southridge in 1997. After Southridge, he became a co-coach with George Gallent in the junior Philippine Basketball League. He then got an offer as an assistant coach for the Cebu Gems in the now-defunct Metropolitan Basketball Association, where he went straight to the finals in his first year. In 1999, he joined the Adamson Falcons and, at 23 years old, became the youngest head coach in the UAAP at the time. His inexperience showed as the Soaring Falcons did not win a game in his first two seasons with the team at 0-28.Those first two years were really trying times for me because, remember, you're inheriting a team that's in last place and then we had to recruit,", he said as he explained the early parts of his 4 and a half years with Adamson. His hard work resulted in a UniGames title for Adamson. Although his time with Adamson wasn’t the brightest of years, it still remains just as significant to him because it made him “realize how tough coaching was.” While at Adamson, he was also offered by coach Tim Cone, who was then his neighbor, to be his assistant coach At Alaska, which he accepted. He juggled learning about coaching through the UAAP and with the Alaska franchise. After his stint with Adamson, he became head coach of the Cebuana Lhuillier Gems of the PBL in 2006, and of the PBA D-League in 2011. In 2012, he left Cebuana and took over the coaching duties of Alaska, replacing Joel Banal. The Elasto Painters spoiled his debut in a score of 107-100 but the Aces recovered and won 104-84 on their game vs. Barako Bull Energy. During the PBA 2012-13 season, he quite made an impression around the league by battling the eventual champions Talk N' Text Tropang Texters to seven games during the 2012-13 PBA Philippine Cup semis. In the 2013 PBA Commissioner's Cup, he helped the Aces win its 14th championship in franchise history, the first in the post-Tim Cone era. His team also came within a game of ousting the eventual champion San Mig Coffee Mixers in the quarterfinals of the 2013 PBA Governors Cup. Because of his achievements, he was awarded as the 2012-13 PBA Coach of the Year by the PBA Press Corps. Two games into the 2014 PBA Governors' Cup, he stepped down as head coach of Alaska. After taking a sabbatical, he took the job as an in-game analyst for Sports5, and eventually returned to coaching, this time as assistant to Norman Black at Meralco.
