Kathleen Hassler, a 68-year-old resident of New Tampa, was one of four students from Lutz-based John Prevatt Karate Studios to earn a black belt during an Oct. 6 belt testing. The achievement was 2 1/2 years in the making for Hassler, a retired nurse who still volunteers at Moffitt Cancer Center. Other John Prevatt students who earned black belts were Miles Soden, Natalie Thomas and Ethan Wagner.
