When health-care professionals are off the clock, they deserve a break from stress. As health-care providers themselves, CV Education's Josh Caywood, a registered cardiovascular invasive specialist (RCIS), and Lisa Caywood, a registered nurse, understand this better than most. That's why their health-care courses in advanced cardiac life support, basic life support and CPR are taught in a laid-back environment that still manages to be clinical and efficient. Their students are encouraged to ask questions as they soak up information.
