Full Profile

Mark Seale, Executive Vice President | Stream Realty Partners
Office tenant representation and occupier advisory for corporate users across Phoenix and multi-market portfolios.

The Challenge Office Occupiers Face
Corporate office users in Phoenix and across North America face mounting pressure to align real estate with business strategy, manage portfolio costs, and navigate complex market cycles while still attracting and retaining top talent.

Many occupiers struggle to coordinate multi-market transactions, negotiate flexible lease structures, and plan for future growth or contraction across diverse geographies.

Legal, financial services, professional services, and institutional users in particular require a strategic advisor who understands both the Phoenix AZ market and national trends to de-risk long-term occupancy decisions.

Mark’s Approach
Mark combines more than three decades of office tenant representation experience with a portfolio-wide, business-first perspective that starts with understanding each client’s operational, financial, and cultural goals.

He advises corporate occupiers on multi-market strategy, transaction sequencing, and workplace planning so that every lease, renewal, relocation, or consolidation supports long-term performance and workforce objectives.

Backed by Stream Realty Partners’ integrated platform, Mark leverages market research, financial analysis, and collaborative deal execution to deliver data-driven outcomes for clients ranging from Fortune 500 companies to regionally headquartered organizations.
