The People Behind
Vanguard Landmark.

Roger B. Cortez is a globally recognized leader in real estate and hospitality development, whose current portfolio features a remarkable range of transformative projects—including a 230-acre island resort in Panama's Pearl Islands, a high-impact affordable residential community in Dallas, and other signature Vanguard Landmark developments. His extensive track record includes executive leadership on the 1,500-acre Punta Mita resort, the Fairmont and Rosewood Mayakoba hotels, the Greg Norman El Camaleon championship golf course, and a $30 million renovation of Acapulco's Princess Diamante resort. A graduate of Trinity University (B.A. Economics) and Northwestern's Kellogg School of Management (MBA), Cortez continues to shape skylines and shorelines with the same visionary precision that has defined his four-decade career.

Mark Teitelbaum built, owned, and marketed a nationally recognized apparel label carried in every major U.S. department store—from Macy's to Nordstrom. That meant negotiating national wholesale contracts, orchestrating multi-market retail rollouts, and leading sales teams through high-stakes closes. Today, as a key member of Vanguard Landmark Real Estate organization, Mark applies that same retail-minded precision to strategic property investment and development. He treats every asset like a flagship brand, bringing a rare fusion of marketing sophistication, wholesale-level negotiation, and an instinct for high-value land acquisition to every deal. Based in Miami and active throughout the state of Florida, Mark now helps investors and buyers navigate real estate with the confidence of a seasoned entrepreneur who has already sold to millions of Americans.
