My  name is Erin Rafanello Ferguson and I live in Nazareth with my two  little girls, husband, and silly cats Hubie and Salem. I love  entertaining my friends and family, cooking, baking, new adventures,  traveling, the great outdoors, holidays, sports, and showing my kids the  magic of the world.

In 2013, I  graduated with my degree in Event Planning/Meeting Management with a  focus on marketing and branding. After deciding to have children, I took  a step back from that field and started taking classes at NYU in  creative writing. Most recently, in 2023, my love for sports led me into  the field of personal training. I am a freelance entertainment  journalist, a marketing/branding manager, a children’s book author, a  certified children’s yoga teacher, a youth sports coach, I run a  cheerleading clinic, and am a certified personal trainer. Of all the  hats I wear, however, my favorite job is being a Mom, but come find me  in the gym and it’s go time!

Come  join one of my classes, M,W,F, 9:30 a.m!
