A lifelong New Hampshire resident and passionate advocate for animal welfare, Renee brings over two decades of experience in the animal care industry.

Renee earned a degree in Animal Science from the University of New Hampshire and has since held a variety of leadership roles, including dog trainer, animal shelter manager, and veterinary practice manager.
As the Executive Director of Helping People Helping Pets, she is deeply committed to preserving the bond between pets and their families. Renee is currently pursuing an MBA in Finance to strengthen her ability to lead and grow mission-driven initiatives within the nonprofit and animal care sectors.
