The entire staff renewed their CPR training with Scott Kohn this morning. Scott is an Excellent teacher who focuses on learning the most important techniques to provide life saving services until the paramedics arrive. We all really enjoyed our training (and the breakfast sandwhich courtsey of Chubby’s!) and we highly recommend Scott as a CPR instructor!
