One life source was fantastic. Very professional and knowledgeable. Quick and efficient. I went in for a refreshment course and certification for CPR since i need it to begin my clinicals for nursing school. He went at the perfect pace not to fast or to slow, made sure to stop frequently and ask if I had my questions and was following through fine. I was attended as soon as I arrived and received my card immediately as well right before leaving. I definitely recommend one life source. By the way if they do not answer the phone when you call don’t allow that to deter you just leave a message and they will call you back in less than 30 minutes!
