The Humane Society for Greater Nashua has been close to Rob Fiero’s heart since childhood. A dog and five cats found their way into his family via the shelter through the years, and Fiero and his wife have volunteered at Humane Society events since 2006. When the organization announced plans to expand its building to enable it to provide more low-cost veterinary care, training, and adoption services to the community, Fiero saw an opportunity to combine two of his passions – animals and trail running – to support the cause.
