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 4 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!

Dive Master in Training

I am an ENTP personality, so that means I am easily bored. It also means that I am a very exciting person to be around. Because of my rare unicorn personality, it has given me the natural ability to try new, exciting things. I have over 200 logged skydives, love to rock climb, and dabble in several areas of martial arts. My biggest joy is to show people how affordable it is to have new experiences. Come get wet with me!
