“My first experience scuba diving was with Steve and Jimmy. I’d never done it before; zero experience. All fear disappeared knowing I was diving with two decorated Navy SEALs. The attention to detail in terms of checking gear an making sure that we were moving at a pace I was comfortable with made me feel super safe!

Never at any moment did I feel danger. Due to that amazing experience, I’m now addicted to scuba diving and can’t get enough of it!”
