Demetrios Panteleakis brings more than 30 years of experience in commercial real estate and has personally transacted deals in 125 US and international markets.

With an extensive background in office, industrial, multifamily, and retail real estate in various U.S. markets, Demetrios’ expertise spans from negotiating transactions to all phases of development, including site review and economic analysis, financing to design, permitting, environmental assessment, remediation, facility compliance, legal, property management, and public relations.

In 2002, Demetrios was recruited by MassMutual Financial Group, a $25 billion Fortune 100 financial services company. During his tenure as Assistant Vice President of Agency Real Estate, he negotiated Class A office leases nationwide for MassMutual’s Life Insurance division and subsequently managed the entire department along with all fixed assets in the field—a real estate portfolio valued at $100 million.

Outside of real estate, Demetrios is a dedicated advocate for improving the lives of at-risk children and adults with mental challenges.
