Caitlin Barlow plays the eco-friendly and ultra PC Ms. Cecelia Cannon on TV Land's comedy series "Teachers." The series revolves around six elementary school teachers who are trying to mold the minds and lives of America's youth even though they don't really seem to have their own lives together at all. Barlow, along with the other members of The Katydids, writes, stars in and executive produces the series alongside showrunner Ian Roberts.

Coincidentally, Barlow was an actual elementary school teacher and earned her M.A. in Bilingual Education from DePaul University. She taught fourth grade in Chicago Public Schools before moving to Los Angeles and becoming a writer and actor. A native of Illinois, she earned her B.A. in History from Illinois State University in 2006. After graduation, she taught English in Osaka, Japan, for a year and then returned to Chicago in 2007 to pursue teaching and performance opportunities.

In Chicago, when she wasn't trying to get nine-year-olds excited about fractions, Barlow was active in the Chicago comedy community, performing in various improvisation and sketch comedy shows at the iO Theater, The Annoyance Theatre and The Second City. She acted in several comedic shorts including "Tool T-Shirt," which won the 2011 Just for Laughs Festival's award for Best Comedic Short. She helped form The Katydids in 2009, and soon thereafter, the group began performing improv shows at various black-box theaters in Chicago. They then moved on to comedic shorts, sketch shows and eventually their web series "Teachers."

In her free time, Barlow volunteers with 826LA and hangs out with her baby Charlotte, husband Frank and their cat Jack in Los Angeles.
