About CTS

Founded in 2008, CTS started as an in-home tutoring service for students within the Lewisburg and immediate surrounding areas.  Beginning by tutoring students in ranges from Kindergartners to twelfth graders, CTS quickly expanded its clientele to adhere to school district needs by writing curriculum for After-School Programs .

As of August 2012, CTS has been residing on Market Street in downtown Lewisburg, serving students of all ages, grades, and subjects, as well as continuing to develop STEM and STEAM curriculum for local programs.  CTS now accommodates over 50 clients a week and educates over 200 different students a year through one-on-one tutoring, After-School Programs, and clubs and camps.
