Have you ever heard of a nonprofit scuba diving shop? Myles and Walter hadn't until connecting with Learn Scuba Chicago. Sam Guess, instructor and board member at Learn Scuba Chicago, comes on this episode to tell our community all about what it's like being a volunteer divemaster and scuba instructor in the Midwest. She also dives deep into her own scuba story and tells us about the mental health benefits that scuba provides for her and her students. To learn more about how to get involved in the programs at Learn Scuba Chicago, visit their website, Learn Scuba Chicago or their Instagram, @learnscubachicago.    ~Reminder~Free Descent is intended as entertainment only and should not replace formal dive instruction. Always follow the direction of your divemasters and instructors and remember to dive within the limits of your training and experience. Stay safe and have fun out there!
