OSS has a good location, good parking, good days offered in a week and on weekends for adults. I gave them a 3 star only co’z the instructors in the adult class are not hands-on. Only stay outside the pool and yelling for the instructions on what to do in the water. They only have 1 hands-on instructor in their adult class with 3 to 5 students. Sometimes the pool is crowded too. It’s hard to teach adult how to swim, it’s the fact so it would be better if they are hands on to their adult students and not just yelling, it’s hard to hear the instructions. In one lane there’s 2 students and sometimes even 3. Their instructor’s should get inside the pool, get wet and have more patience teaching their students. no yelling! old people have a hard time hearing
