I just renewed my CPR/AED/First Aid certification through a Lifework, Inc. American Heart Association certified instructor named Chad Smith. I have been obtaining the CPR certification since 1985, and this session was by far the most instructional. Chad had an incredible classroom which contained tools which enabled me to understand rescuer CPR and First Aid at a greater level than I had in the 29 years prior. I highly recommend Chad for my fellow fitness professionals to maintain their certification. Chad is a registered nurse with a great ability to train and who has an abundance of practical experience to enhance course instruction.
