Forty years of homes
built exactly right
Kitchens, bathrooms, whole-home remodels, and accessible design across Tampa Bay — crafted by a team whose reputation was built one project at a time — since 1985.
"We don't leave until you love it. That's been our promise since the very first day we opened our doors in 1985."
1947 – 2025
A legacy built on integrity, craft, and people
It is with deep sadness and heavy hearts that we share the news of John Marzulli's sudden and unexpected passing. John was more than the founder of Emerald Contractors — he was the heartbeat of this company, a mentor, a craftsman's craftsman, and a man who genuinely loved every client whose home he touched. His loss has been felt profoundly by our entire team, our clients, and the Tampa Bay community he served for over four decades.
John always said that building is about relationships — and the relationships he built will outlast any structure ever raised. We are grateful for every project, every handshake, and every promise kept. His legacy is written into the walls of hundreds of Tampa Bay homes.
Field
With over 30 years of hands-on construction experience, Mike has been an integral part of the Emerald Contractors family for years. From his roots working alongside his father in the trades to leading complex projects across Tampa Bay, Mike's expertise, calm leadership, and genuine care for clients make him the natural steward of John's legacy in the field. Under Mike's direction, the same standard of craftsmanship and the same client-first promise John built this company on will continue — without compromise.
Office
Diane has been the backbone of Emerald Contractors' operations since joining the team in 2017, bringing over 40 years of accounting and management expertise to the company. Meticulous, dedicated, and deeply loyal to the Emerald family, Diane ensures that every client relationship is handled with the same personal care and attention to detail that John demanded from day one. As Co-Owner, she continues to oversee all office operations, client communications, and the financial integrity that has defined this company for four decades.
Emerald Contractors remains committed to John's founding promise. Under the leadership of Mike and Diane, every project will continue to be delivered with the integrity, craftsmanship, and personal attention that has defined this company since 1985. His legacy lives on in every home we touch.
"The A-Team of construction who really care. Every person of Emerald Contractors came through. You all deserve a medal."
"John and his team completely transformed our master bath. On time, on budget, and better than we imagined."
"Kitchen of our dreams. The design-build process was seamless — we always knew what was happening next."
40 years strong — and still building
There are very few businesses that last 40+ years, much less construction companies. If you count the formation of a home building company back in 1970 and subsequent development companies, that is over 50 years of building experience.
How have we stayed in business for that long? Our unwavering commitment to our clients and our craft. We don't take shortcuts. We don't cut corners. We build things right.
