Tim Dieffenbacher, Chief Financial Officer

As the Chief Financial Officer of KW, Tim Dieffenbacher brings extensive experience in corporate finance, accounting, capital markets, operations, and governance, most recently serving as CFO of a publicly traded real estate investment trust in Dallas.

Dieffenbacher previously worked alongside Czarnecki at Broadstone Net Lease (NYSE: BNL) and Broadstone Real Estate (BRE), where they partnered to scale the business and build best-in-class operational infrastructure.

Dieffenbacher served as Senior Vice President, Chief Accounting Officer, and Treasurer at BNL and BRE.

A Certified Public Accountant, Dieffenbacher is passionate about developing high-performing teams, streamlining complex processes, and fostering transparency through disciplined financial management.

“What drew me to Keller Williams was the people, the culture, and the opportunity to work with Chris again,” said Dieffenbacher. “There’s a genuine sense of shared purpose and entrepreneurial spirit here that’s hard to find.”

“I’ve always been motivated by the chance to work with good people, solve challenging problems, and build something meaningful — and that’s exactly what I see at Keller Williams,” said Dieffenbacher.

In March, Stacie Herron was officially appointed Chief Operating Officer and Chief Legal Officer, after serving as interim COO. She joined KW as CLO in March 2021 and went on to serve as Chief Legal and People Officer, followed by CLO and Chief Administrative Officer.

In her role at KW, Herron leads the Growth, Franchise Systems, Legal, Risk Management, Human Resources, and Workplace Experience teams.

Herron joined KW after more than 12 years at a publicly traded global real estate services firm, where she served as executive vice president, general counsel, and corporate secretary.

Earlier in her career, Herron was an in-house corporate attorney at a NYSE-listed retail company, overseeing corporate, governance, finance, and international legal matters.

“Keller Williams is a remarkable organization, fueled by passionate, purpose-driven people,” said Herron. “I’m grateful for this opportunity to collaborate with the many talented teams across the business.”
