He has been a member of the New England Patriots, Seattle Seahawks, Buffalo Bills, Jacksonville Jaguars, Las Vegas Raiders, and Minnesota Vikings of the National Football League (NFL).

Born and raised in Bend, Oregon, Hollister graduated from its Mountain View High School in 2012 and was a three-sport letterman in football, basketball, and baseball.

Hollister then played three seasons (2014–16) under new head coach Craig Bohl at the University of Wyoming in Laramie in the Mountain West Conference.

[2] He was a team captain and first-team all-conference as a senior,[3] when the much-improved Cowboys played in the conference championship game and Poinsettia Bowl.

[10] Hollister put together a solid preseason performance while competing with James O'Shaughnessy for the Patriots possible third tight end spot behind veterans Rob Gronkowski and Dwayne Allen.

Hollister ultimately won the spot as an undrafted rookie, and made his NFL debut in Week 2 against the New Orleans Saints, recording his first career catch, which went for seven yards.

[20] Earlier in the same game, Hollister scored the first touchdown of his NFL career, a one-yard reception late in the first half, after drawing a pass interference penalty in the end zone.

However, he was tackled inches short of the goal line by rookie linebacker Dre Greenlaw, and Seattle turned the ball over to lose the game and the National Football Conference (NFC) West title.
