Summer Skills Temporary Shutdown (As of October 21, 2019)

It’s with sadness that we at Tri-C say good-bye to all our wonderful customers.  It’s been an amazing 28 years helping students and talking to parents, teachers, students, principals, tutors, curriculum directors, Title I coordinators, summer school facilitators and everyone who used or recommended the Summer Skills books.   We are still in negotiations with another company to carry on the publication of the Summer Skills books. Because of this, we are unable to accept orders at this time. We will keep you informed when we have something definitive to share.  Meanwhile, thank you, thank you, thank you!
