Meet Our Team in Sun Prairie
Chelsea Foster
Area Director
Although Chelsea has been diving since 2007, she has been involved in the scuba industry her entire life with her parents owning and operating SeaVentures for 31 years. After receiving her Business degree while playing collegiate volleyball, she explored her passion for working in bakeries. However, she found herself back at the family business pursuing her dive professional certifications and eventually worked her way through most of the swim, scuba, and marketing roles then into management. Since becoming a dive pro and running the Alpharetta location, she has traveled the world sharing her passion and excitement for the underwater world and visited amazing places like Bonaire where she even attended kids camp growing up each summer to Galapagos with the most advanced and incredible diving yet. She loves to teach and grow open water students into great divers and loves the opportunity to travel to new places making memories and sharing experiences with you!
