Grew up playing golf at Mission Viejo Country Club, a Robert Trent Jones Sr. design which opened in 1967. The course is where 16-time PGA TOUR winner Mark O'Meara fell in love with the game as a kid. Locals call the course, "Mission Impossible."

As a junior golfer, worked with famed instructor Jim Flick, who was inducted into the World Golf Teachers Hall of Fame in 2002, followed by the PGA Golf Professional Hall of Fame in 2011. Hossler and Flick worked together for six years (ages 11-17 for Beau), until Flick passed away in 2012 (at age 82) after a battle with pancreatic cancer. Hossler said Flick was "like a grandfather to me."

Prepped at Santa Margarita Catholic High School in California. Notable alums of the high school include 2002 Heisman Trophy winner and three-time NFL Pro Bowl selection Carson Palmer (Class of 1998), as well as multi-time NBA All-Star Klay Thompson (Class of 2008).

Teammates in his three and a half seasons at Texas (2013-16) included multi-time PGA TOUR winner Scottie Scheffler (2014-16 -- two seasons), TOUR winner Cody Gribble (second half of 2012-13 season), Doug Ghim (2014-16 -- two seasons), and Kramer Hickok (2013-15 -- two and a half seasons).
