I have worked with several crossfit gyms in the past, and Mercer Island is amazing! They care about their athletes, have an amazing family vibe, they have fun with each other, and of course they work hard! It has been a pleasure getting to know Corey, Allison, and the rest of the staff… they welcome all comers, and do a great job of finding out where you are in your fitness and work with you from there! Top grades!
