Larry Gelwix has been the coach of the Highland Rugby team since its founding in Salt Lake City in 1973. The movie Forever Strong  (2008) was inspired by him and his team’s history. The Highland rugby team has compiled an unrivaled winning record since its founding in 1973. Gelwix is a native of California. He served a mission for The Church of Jesus Christ of Latter-day Saints in the midwestern Central States Mission. He has bachelors and masters degrees from Brigham Young University in Organizational Communication. He also played rugby for three years at BYU under coaches from New Zealand. He became an instructor at Church seminary adjacent to Highland High to earn money to pursue a doctorate at Purdue University. He became an assistant football coach during the fall season and a wrestling coach in the winter. He missed coaching in the spring, and having played rugby at BYU, decided to start a rugby team at the high school. 

Gelwix quit teaching seminary full time after four years and opened a travel agency in 1979.  He coaches rugby in the evenings. Rugby is not an official high school sport and the team must raise all funds required, including travel. All 11 coaches are volunteers. When the movie Forever Strong was made, Gelwix was not paid for his story. Gelwix insisted that the movie had to be about the players and not him. Gelwix and his wife Cathy are the parents of five children. Known as the Getaway Guru, Gelwix has for 17 years been the co-host of The Travel Show, a weekend program heard on KNRS Radio in Salt Lake City and various stations throughout the Intermountain West region.
