Shelly Argy Poston Joins Miami-based Gridline Properties as a Senior Associate



Gridline Properties, a full-service commercial real estate brokerage firm based in Miami’s urban core, is pleased to announce that Shelly Argy Poston has joined the company as a senior associate. With over five years of commercial real estate experience, Poston’s role will focus on the sale of multifamily properties and development sites within South Florida.



Prior to Gridline Properties, Poston worked at Marcus & Millichap where she also focused on multifamily and development sales, and in 2019, she won the Prospector of the Year Award. As of September 2022, Poston’s sales in 2022 alone have reached the $21.5 million mark. After nearly four years at Marcus & Millichap, Poston’s decision to join Gridline Properties was motivated by its culture of innovation and collaboration.


Her methodology stems from her studies of organizational psychology, which she earned a master's degree at the Interdisciplinary Center (IDC Herzliya, now known as Reichman University) located in Tel Aviv, Israel. As part of her studies, Poston evaluated the ecosystems of struggling companies and guided them in ways to improve strategies and streamline communication to keep them flourishing. This knowledge has helped Poston throughout many of her negotiations and while dealing with clients.


“Gridline Properties is thrilled to have Shelly join the team,” said Alfredo Riascos, broker and principal at Gridline Properties. “We are certain that she will add value and new skills to our growing team of successful agents.”
