Cassie Kinnison - Assistant Instructor
I got bullied into getting certified to dive when my youngest daughter and husband wanted to take a trip to Australia to dive the Great Barrier Reef. I didn’t want to be stuck on the liveaboard all day, so I decided I should probably get certified so I could join them. Who would want to miss out on a trip to Australia? That trip never came about, by the way, but I did get certified while I was in Grenada on vacation. I didn’t dive again till the following year when we went to St. Lucia. While there, I met a great instructor that took me through an underwater video and photography certification. After that, my mind was blown, and I haven’t stopped diving since. I’ve done a ton of certifications since then, (wink wink) because now I’m also an SSI Assistant Instructor. I love to help people, so I might as well be able to certify them as well while doing it. Obviously, I am leading into telling you my passion became underwater photography. It has taught me to slow down, slow my breathing, and see everything, absolutely everything in this underwater world. I have the best dive buddy, my husband, who pretty much will take me anywhere I want to go (unless the water is cold he said). We dive together and laugh and talk about the things we found in this large aquarium we call the ocean. Capture the moment and relive the experience.
