Madison Marquette continues strategic expansion with boutique merger

Madison Marquette, a national owner, investor, developer and integrated service provider, announced its merger with The Roseview Group, a boutique institutional real estate investment and advisory company based in Boston, MA.

The combination continues Madison Marquette’s strategic path forward in growing its platform, bringing capital markets and corporate advisory capabilities to the company and augmenting its national platform.

Roseview’s Chief Executive Officer, Vince Costantini, will serve as CEO of the combined firm.


“As we sought to expand both our investment and property services practices in 2018, we were seeking the best talent as well as the best cultural fit for our company and our clients,” said Amer Hammour, Executive Chairman of Madison Marquette. “Vince and the Roseview team stood out for many reasons. ”

Costantini brings over 35 years of industry leadership as a real estate fund manager, investor and institutional advisor to his new role as CEO of Madison Marquette.

He said, “The combination of Madison and Roseview creates a national platform that provides a unique new industry choice for owners, investors and corporations seeking a service partner with an ownership perspective focused on long-term value creation.”

When he assumes his CEO role, Costantini will work in partnership with Hammour and president John Fleury as a managing principal of the combined firm.

He will have primary responsibility for leading and expanding the company’s investment management practice and Fleury will focus on the continued growth and optimization of Madison Marquette’s integrated third-party services.

Hammour will continue to lead major strategic projects, while also focusing on investment strategy and client development.
