As a child in Roswell, Reagan Koski noticed that her mother was a busy volunteer -- "she did everything."
"I think I grew up thinking this is what you do when you get older," Koski said. "You give back."
The Winnona Park resident does that a lot now.
She's active in her childrens' schools and serves on the board of directors for the (now called the Wylde Center) and the committee.
For the tour of homes, she says she "secures the houses," a task that requires months of planning. The home where she lives with her family was included on last year's tour.
She's served as president and vice president for the Winnona Park Elementary PTA, volunteered at the school book fair and served as a room parent.
Now she's helping at the Fifth Avenue Academy, where her daughter is a fifth-grader, and Renfroe Middle, where her son's an eighth-grader.
She also taught Sunday school and volunteered on the Lake Claire and Decatur Gators swim teams.
Reagan went to college at Webster University in St. Louis. There she met her husband, Decatur High teacher Geoff Koski, who didn't grow up in Decatur but had visited family here.
After living in Asheville, N.C., they moved to Decatur about eight years ago.
She owns an interior design and kitchen renovation firm, Revive and Design.
The City of Decatur named her a Hometown Hero for 2010, saying "Reagan is well known in the community because of her warm and friendly personality and through her involvement in so many varied activities."
