19 years ago I found CLST

After watching my father lose his life in 1969 because no one was trained in CPR, I decided to become a paramedic and help save lives.

 In 2001, I started CLST with the goal of teaching thousands of people how to save a life.”

“I have taken classes many years with JR. He taught me so much.  As a nurse, it’s hard to impress me…and he does over and over again. Great instructor.

He knows all the guidelines and will teach you everything you need to know to save a life.”
