Katharine Eagan, the Chief Operating Officer for HART, was listed on Mass Transit magazine's Top 40 Under 40 list.
The trade publication, which touts itself as the only such entity dedicated to public transportation, made the announcement on Tuesday.
Eagan has been with the Hillsborough County transit agency since 2009, when she took over as Chief of Service Development; a year ago she was promoted to COO. She started at HART after working at the Maryland Transit Administration in Baltimore, as well as public transit agencies in Dallas and San Angelo, Texas.
In a press release, Eagan's boss — HART CEO Philip Hale — said, "Personally, she is the most intelligent transit professional that I have worked with in my 39-year career. I am confident Ms. Eagan will continue to be an innovative leader in the transit industry, and a dedicated public servant to this community as significant transit improvements are implemented in the near future, such as MetroRapid North-South."
