Meet Our Trainers

Callie Krosin 

I am a recent graduate of The Park School and now in the Class of 2025 at Emerson College in Boston. I am studying journalism and an athlete on Emerson’s NCAA DIII Women’s Lacrosse team. I am a CrossFit Level 1 and I started at Arenal Fitness in March of 2020. I have trained all ages as well as many types of athletes. Outside of fitness and lacrosse, I love spending time with friends, family, and my dogs!
