Other teams have asked what the secret to Mandarin’s success is.  The culture of the team is that everyone is responsible for sharing their knowledge, supporting teammates, and maintaining high expectations of effort/performance.  Coach Sitowitz’ s philosophy is simple, “Life isn’t meant to be lived alone.  Here’s our secret.  Find what you love and find friends who love it just as much.  Laugh together, dream together, and create together to make each other better.  When it gets hard…. you will be able to get by with a little help from your friends.”
