Family Owned and Operated

Bottoms Up Scuba is an Indiana based Scuba Diving shop and instruction facility. We offer PADI dive courses to the central Indiana region. Initially, we started as a small mobile teaching operation and have grown tremendously since we began 5 years ago. We think our success comes from the great people we work with and treating everyone we teach like our own family. Check out what we are all about and call us to see how you can be a part of the Bottoms Up Scuba family!

I got into scuba diving because my little brother Dean talked me into trying it, and I loved it. I attended Ball State University for five years for General Education. My hobbies include Playing Rugby for the Indianapolis Impalas, exercising, songwriting, rapping, and hanging around loved ones.
