The 2009 GNAC Coach of the Year also coached Emerson's men's volleyball program.

Prior to his Emerson appointment, Letourneau was a part-time head coach at Rhode Island College, his alma mater, from 2002-06. Improving the team's win total during each of his first four seasons, Letourneau led the Anchorwomen to a shared of the Little East Conference (LEC) regular season crown in 2004 and to the league tournament title match in 2006, both program firsts. He also served as an assistant women's basketball coach.

Letourneau began his coaching career at the high school level, working as the head boys' and girls' volleyball coach at Mount Saint Charles Academy in Woonsocket, R.I., for four years. He led the boys to a state title in 2001 and the girls to a state runner-up finish that same year. Letourneau was named coach of the year five times, including on four occasions for the girls. He also was a successful girls' basketball coach for seven years at Lincoln High School, winning a state title in 2005.

Earning a bachelor's degree in psychology from Rhode Island College, Letourneau is a 2000 graduate. A personal trainer since May 2005, Letourneau has certifications from the American Council on Exercise (ACE) and the Aerobics and Fitness Association of America (AFAA).

He assisted with the overall coaching, supervision, recruiting process, and organization of the Emerson program. During his tenure, he saw three student-athletes garner conference player of the week honors and another receiver rookie of the week accolades.

While still a student at Mount Ida, Yao became an assistant coach at Boys Latin Academy in 1997, where he helped both the girls and boys teams qualify for the MIAA State Playoff Tournament in each of his five seasons as an assistant. In 2011, Yao became a coach for both the MBSC Nike Volleyball Camp and Smash Volleyball.

A 2008 graduate of Mount Ida with a bachelor of science in sports management, Yao was a Dean’s List student and also received the President’s Merit Scholarship. He was a two-year student-athlete for the Mustangs, where he was an outside hitter, middle hitter, and defensive specialist/libero.
