Nick Panarelli
REALTOR®
With a background in hospitality and customer service, I specialize in helping first-time homebuyers and investors achieve their goals. Known for thinking outside the box and always being accessible, I prioritize my clients’ needs above all. I’m actively involved in community service, including the Central Mass Pet Pantry, and my passion for hockey has taught me the value of teamwork, both on and off the ice. When I’m not working, I enjoy spending time with my dog, Hercules, expanding my real estate knowledge through continued education, and experimenting with new recipes in the kitchen.
