SureFire CPR in Corona is the place to go. On my current visit, I had 2 excellent instructors who were both helpful & constantly making sure that I & other students were using the correct techniques for Adult/Kid/Infant CPR. Both Trenton & Zack, the instructors, were always available for questions and for making positive comments about the correct techniques to use for cpr. They were constantly giving all students positive feedback and helping those who needed it during cpr training. At the end of this section, you do take a short test, but no worries, it is easy. I have to say that I was truly impressed by SureFire CPR and especially with their Corona location. They truly live up to their promise of professional instructors and a clean learning environment.
