About Keri

IMG_6187 (1)

Hi, I'm Keri! I'm a married mom of 3 boys. My twins, Drew (L) and Michael (R) are 13 yrs. (7th grade), CJ is 6 (1st grade) and is everything you'd expect in a little brother! These boys keep us busy!

My husband, Ed, is a health teacher and Head Football Coach for Boston College High School.

Our lives happily revolve around football, hockey, and lacrosse. As former athletes (my husband played football in college and I played basketball) we know the importance and value of sports for staying active, healthy, instilling teamwork and learning life lessons. Our weekends are full of games and practices and lots of travel, but we love it.

Like many of my clients, I understand the juggling act of work, family, and self-care. I'm here to make fitness and nutrition simpler for busy women, helping them achieve consistent results without unnecessary stress.

With With years of experience in fitness and nutrition, I'm dedicated to helping women like you feel their best....without losing their minds!
