Nelson Castillo is more than just a real estate professional—he’s a trusted neighbor, community advocate, and go-to guide for families looking to plant roots in the Massachusetts and New Hampshire. With Lamacchia Realty, Nelson helps his clients turn the dream of homeownership into reality, making the process simple, approachable, and rewarding every step of the way.

Before stepping into real estate, Nelson built a strong career in sales and leadership, mentoring new professionals and honing his skills in negotiation and problem-solving. Today, he brings that same dedication and people-first mindset to his clients—whether it’s a first-time buyer searching for the perfect starter home, or a growing family ready for their next chapter. His approach is simple: listen, care, and go above and beyond to make sure every client feels supported and confident in their decisions.

Born and raised in Lawrence and now living in Haverhill, Nelson has deep roots in the community he serves. When he’s not helping clients, you’ll find him spending time with his two daughters (his greatest inspiration), traveling, or giving back through coaching and refereeing local basketball. A former college baseball player, Nelson brings the same teamwork and discipline from the field into his real estate practice—always ready to work hard and deliver for his team.

For Nelson, real estate isn’t just about buying and selling homes—it’s about building lasting relationships and strengthening the community he loves. Clients know they can count on him to be their trusted advisor long after the keys are handed over.
