Allison Nichols Carroll was a houseguest on Big Brother 9.

Her "soulmate" in the game was Ryan Quicksall. Allison could be considered the season's villain, as she was seen as a tough competitor and not well-liked. She threatened to expose Jen and Ryan as a couple outside of the house unless they "helped her." Allison was the first houseguest evicted after the dissolving of the "soulmate" twist, with the vote being between her and Ryan after sirens sounded during a fake eviction. Allison was evicted in a unanimous 6-0 vote placing 10th.

Allison attended Rollins College in Winter Park, Florida and graduated with a bachelor of arts/psychology degree in 2002. She also spent a semester at sea, world travel, in the spring of that year.

She currently works in pharmaceutical sales where she works with specialists in the pulmonology/allergy sector. She is also part owner of a pottery studio and is an accomplished painter. Allison was interested in becoming a professional gambler but failed miserably at it. Now she has a strong aversion to gambling and doesn’t do it at all.

She describes herself as confident, agile and sexy. She is a world traveler who committed over 1,000 hours to Mother Teresa’s orphanages in India, Vietnam, China and Japan. Her favorite activities are exercising, critiquing movies, reading and painting. She believes that people gravitate toward her and that she commands attention naturally when she enters a room. But, she admits that while guys usually like her, women usually hate her. For the past few years, she has actually juggled more than two men at a time while having relationships.

Her birth date is July 24, 1979.[1]
