Fitness Philosophy:

Working out and staying fit has always been a passion of mine. I have played almost every sport and I coached club water polo so I love seeing my team grow to love the sport and what they do everyday and I hope to bring this enjoyment to the students in my class, too. It is so amazing that our body's have the strength to do what they do everyday and that we get to glorify God through this.
