Patti is one of the friendliest girls in school, and gets along with almost everyone. She met Doug when he first moved to Bluffington, and he instantly fell in love with her. She is a very well-preforming student, in both academics and sports. She also formed her own softball team, "Patti's Pulverizers", after being rejected from the school team. She also gets jealous when Doug is with other girls too.
Earlier in the series, while Doug had a huge crush on her, her feelings were only hinted at, though this was because at that point, the series was only from Doug's point of view. The first time her affections were explicitly shown was in "Doug to the Rescue" from the first season of the Nickelodeon series. She also mentions in "Doug's Magic Act", from the third season of the Nickelodeon series, that Doug is her favorite person to be with. In the Disney series, Guy Graham, an 8th grader, showed affection for her, though she never appeared to be completely interested, only seeing him as a friend.
In Doug's 1st Movie, she didn't believe Doug that Lucky Duck Lake was polluted, and this caused her to end up going with Guy to the Valentine's Dance. However, after finding out that Guy was planning on exposing the monster to be destroyed, she ended her relationship with him and began to dance with Doug for the remainder of the movie.
In the final episode of the Disney series, she asks Doug out on a "date-date", thus causing the two to become an official couple.
At home, she lives with her dad. Her mom died in a car accident, which her dad was also in, but despite surviving, became wheelchair-bound as a result. It's unknown whether Patti was present during the accident.
