When she was 6 months old, Marie and family moved to Plano, Texas. Marie was a self-described tomboy while growing up. She went to college at Louisiana State University to become a veterinarian. While in college, she started modeling, and in 2000, she started modeling for Playboy and appeared in several newsstand special editions. This affiliation led to Marie's selection as Playmate of the Month for August 2003. She graduated LSU with a doctorate degree in veterinary medicine. While under contract as a Playboy model, Marie resided in New Jersey with fellow Playboy Playmate Lindsey Vuolo. During this time, Marie worked as a practicing veterinarian, while continuing to model part time.
In March 2004, she appeared in an episode of Fear Factor with her older sister, Katie. In June 2006, Colleen launched her personal adult-themed website, ColleenMarie.com.
