Mark is mostly known for being apart of a showmance with Elena Davies known as "Marlena." His association with his friends Cody Nickson and Jessica Graf made him a target and was accused of flip flopping by the other houseguests. He also clashed with Josh Martinez almost getting physical when Josh banged pots and pans. Mark tried to convince Jason Dent to make a move against Paul Abrahamian but was unsuccessful and Elena was evicted during the Double Eviction with Jason as the HOH. Mark won safety four weeks in a row by winning a Power of Veto or Temptation Competition but was unable to save himself during week 8 when he was evicted and became the third member of the jury. Mark along with Elena, Cody, Alex Ow and Jason decided Paul overplayed and voted Josh the winner.

What do you think will be the most difficult part about living inside the Big Brother house?
Seeing the same people every day, but I've been through a similar experience studying abroad. Which past Big Brother cast member did you like most: Brendon Villegas from Seasons 12 and 13. He basically said, "It's me and my girl vs. the house. Let's go." Do you have a strategy for winning the game?
Yeah, try to read people and relate with everybody, be real, don't get caught up in stories, earn people's trust and keep it. My life's motto is… Fear none, regret less. What would you take into the house, and why?
- A pair of Jordan's because I'm a sneaker head
- Protein because you can never have too much protein
- iPod because I love my music Fun facts about yourself:>br>
- Studied abroad
- I love chess and I'm real good
- Went to an NFL regional combine
- Division 1 football player
