Solar Swim and Gym has been a focal point for teaching swimming lessons in the city of Antioch for over 70 years. In 1955, formally known as C Street Pool, original owners Clark and Ingrid Gelhaus started off small, but based off of their growing reputation and fast results, they had students come from all over the Bay Area to partake in swimming lessons. After many years of a successful community pool, Clark added on the gym in 1974, and thus C Street Pool became what it is currently known as, Solar Swim and Gym. Mr. and Mrs. Gelhaus worked hard to make Solar Swim and Gym a family friendly gym with a country club type setting, and it shows as Solar Swim and Gym is one of the oldest operating businesses in Antioch. New Owners Htet Aung and Wint Lwin carry on the same values implemented by Clark and Ingrid Gelhaus that helped make Solar Swim and Gym a piece of Antioch history.
