S3 essentially changed my life when I was in Boston -- and I don't say that lightly. I had very few friends and was having a hard time meeting people, but as soon as I started playing sports with S3, I immediately gained a great community of people to play sports with, hang out with, and generally just share life with!  - Rob W

When I first moved to Boston, I didn't really know anyone. S3 changed that. I have had so much fun, and I now have a great group of friends. S3 is more than just a sports league. In addition to sports, there are lots of fun activities (e.g., Celtics games. Karaoke. NYE, trivia nights, etc.). Jess, the founder of s3, is awesome! She constantly goes above and beyond to make sure everyone has a great time. - Staci F
