Greenstone Partners, a leading commercial real estate investment and advisory firm, today announced the strategic acquisition of D4 Realty, a Chicago-area brokerage specializing in office and industrial transactions. As part of the acquisition, Dave Schraufnagel, founder and principal of D4 Realty, will join Greenstone Partners as Senior Director of Investment Sales & Leasing.
The acquisition expands Greenstone’s investment sales and leasing platform, adding established client relationships, transactional expertise, and a two-decade track record across one of the country’s most competitive commercial real estate markets.
“In D4 Realty, Dave built a highly respected brokerage business rooted in client successes, market intelligence, and consistent execution,” said Clarence Marsh, Chief Operating Officer at Greenstone Partners. “His selection of Greenstone for the next chapter of his business is a powerful market signal; a broker of Dave’s exceptional caliber choosing our platform validates the strength, sophistication, and trajectory of what we are building here. Dave is the textbook entrepreneurial, results-driven, and high-integrity professional we aim to attract as we grow our footprint in the Chicago market.”
Dave Schraufnagel brings nearly 25 years of experience across office and industrial investment sales and leasing. Since entering the commercial real estate industry in 2003, he has advised landlords, tenants, investors, and developers throughout the Chicago metropolitan area, with a focus on key urban commercial submarkets.
Schraufnagel’s tenure at D4 Realty cemented his reputation as a trusted advisor, consistently executing transactions across market cycles and maintaining long-standing client relationships. Over the course of his career, Dave has advised clients through more than 600 combined lease and sales transactions, spanning a highly diverse variety of asset classes and submarkets.
In his new role, Schraufnagel will expand the scope of Greenstone’s brokerage platform, leading investment sales and leasing assignments while supporting the firm’s continued growth across the Chicago-area market.
“Joining Greenstone Partners is an exciting next chapter,” said Schraufnagel. “The firm’s vision for the Chicago market aligns with everything I built at D4 Realty. Together, we have the platform, the capital relationships, and the market presence to deliver exceptional outcomes for our clients across both investment sales and leasing.”
The acquisition of D4 Realty reinforces Greenstone Partners’ commitment to building a more comprehensive commercial real estate platform in the Chicago metro area. With the addition of Dave’s practice, the firm is positioned to serve a broader range of clients, ranging from institutional investors seeking acquisition and disposition counsel to corporate occupiers navigating today’s dynamic office and industrial landscape.
D4 Realty’s existing client relationships, proprietary market data, and transactional infrastructure will be integrated into the Greenstone Partners, effective immediately.
