Front Office Lead

Sara was born and raised in Grass Valley, doing all the things that Grass Valley-ers do. Dance, theater, music, until finally discovering her true passion of reading. After many years of living here she moved to New York. After 8 years, she  decided to move back to her home town and realized that, on top of reading, she loved helping people. She found herself working fo Fit for Life doing just that. 

 On the weekends she retreats into her true nature of book-nerd-hermit reading all the books in a literal cabin in the woods. 

When she grows up she hopes to find a career that combines helping others and reading all the books. Preferably in PJs 24/7 with a dog and a giant cup of tea.


Paige Simpson

Office Assistant/ Aide

Paige was born and raised in Placer County but is no stranger to Nevada County. In her free time she enjoys exploring local rivers with her dog, 4x4ing with her friends, and photographing all of nature's beauty. When she's not out exploring, her love of the outdoors keeps her digging in the garden all spring and summer. Cooking, reading, and crocheting are a few hobbies that keep her busy when the outdoors aren’t calling. She has explored a few different career paths but has found her true calling with medical administration. Always having a passion for helping others but not interested in a full medical professional position she has found a happy medium helping others from behind the desk.
