Sierra was a castaway on Survivor: Worlds Apart and was part of the Escameca (Blue Collar) tribe. Right away she found herself on the bottom of the Blue Collar tribe, alongside Lindsey, and her other tribe mates questioned her work ethic. Escameca won the first several immunity challenges, keeping her safe. Sierra and Lindsey decided to target Rodney when they finally went to Tribal on Day 11 because he was sexist, but the majority split the vote between her and Lindsey, with Lindsey ultimately going home. On Day 12, her tribe was swapped, although Blue Collar remained in the majority. She became a split vote when it came down to voting for Joe or Joaquin, ultimately voting against Joaquin.
She merged on Day 17 and joined the majority alliance consisting of White Collar minus Shirin and her Blue Collar tribe. Despite Kelly being Idoled out, Sierra and the Blue collars systematically eliminated the No Collars (minus Will). Sierra also turned on Mike with the other Blue Collars after Mike blew up Rodney’s alliance. Sierra found herself the swing votes for the next several eliminations, with her ultimately siding to stick with her Blue Collar tribe mates. Sierra teamed up with Mike and Carolyn during the final 7 tribal, with Mike playing his Idol to send Tyler out of the game. With Mike continuing to secure immunity, the remaining players had to turn on each other at Final 6, with Sierra joining the others in voting for Carolyn, but Carolyn played her Idol, sending Dan home. At Final 5, Mike won yet another Immunity, so Sierra and her allies had to target one another. She assumed Mike and Carolyn were on board with getting rid of Rodney, but after openly stating she was a threat, she was blindsided in a unanimous vote, becoming the 14th person voted out and the 7th member of the jury on day 37.
Sierra happens to be the second tallest female to ever play the game at 6’1’’, only behind Crystal Cox from Gabon. Sierra only received votes at her first and last Tribal Councils and was the only person unanimously voted out in Worlds Apart. She appeared as a Price is Right Model with Ozzy during the Survivor Price is Right Special. Sierra is one of the 20 castaways rumored to return for Survivor: Game Changers – The Mamanuca Islands, premiering next Spring. She was apparently an alternate for Natalie Anderson, who declined to appear due to school. She and Mike Holloway were rumored to be dating after the show aired, but that was short-lived, as he is dating BB17 contestant Meg.
