PHOENIX – July 30, 2025 – Stream Realty Partners, a national commercial real estate firm offering an integrated platform of services, announces the strategic addition of Mark Seale as Executive Vice President and Ben Seale as Senior Associate in its Phoenix office.
With more than 30 years of experience in commercial real estate, Mark Seale joins Stream from Avison Young, where he most recently served as Principal and Market Leader. He began his career at Trammell Crow Company and has since held leadership roles focused on tenant representation and advisory services. At Stream, Mark will concentrate on advising corporate office occupiers, leveraging his deep transactional expertise across industries such as legal, financial services, and professional services.
“I’ve spent my career prioritizing client success, and it became clear through this process that Stream offers the ideal platform to continue that mission,” said Mark Seale. “The firm is incredibly resource-rich, collaborative, and filled with exceptionally talented professionals who care deeply about doing the right thing. Stream’s approach isn’t about being the biggest—it’s about being the best. That mindset truly resonated with me.”
Ben Seale joins Stream as a Senior Associate, specializing in both office and industrial tenant representation. Previously with Avison Young, Ben brings a fresh, energetic perspective and a background in both residential and commercial real estate. At Stream, his focus will be on delivering value-driven, tailored solutions for industrial and office occupiers throughout the Valley.
“What drew me to Stream is the investment they make in their people—everything we need to succeed is already in place,” said Ben Seale. “The firm’s culture of excellence, support, and forward-thinking strategy is exactly the kind of environment where I can grow and deliver outstanding results for my clients.”
Mark and Ben will work alongside Executive Managing Director & Partner Tiffany Winne and the regional team to continue building Stream’s best-in-class occupier services platform in the Phoenix market.
“Mark and Ben bring a stellar combination of experience, energy, and professionalism to our team,” said Winne. “Mark’s decades-long track record, thoughtful leadership, and deep client relationships are complemented by Ben’s drive, fresh perspective, and strong foundation in both office and industrial brokerage. Together, they represent the kind of high-caliber talent that aligns perfectly with Stream’s culture and vision. We’re excited to welcome them and confident they’ll make an immediate impact.”
