Thomas Windels
"We started by walking the buildings our grandfather collected rents from. We never really stopped."

Windels operates inside Marcus & Millichap's Stewart Group. We bring institutional-grade analytics, off-market relationships built over years of direct owner outreach, and the discipline of family-run advisory.

Thomas Windels
Investment Sales Advisor

Thomas focuses on multifamily, mixed-use, and commercial investment sales in Lower Manhattan — Lower East Side, TriBeCa, and Chinatown. He sources off-market opportunities through direct owner relationships and data-driven prospecting, working with both local operators and outside capital.

George Windels
Research & Analytics Partner

George focuses on property data analysis, ownership research, and market intelligence that underpins every transaction. His work on ACRIS records, zoning analysis, and development rights surfaces opportunities before they reach the open market.
