Keller Williams Realty hired corporate finance veteran Tim Dieffenbacher as its new CFO and made interim COO Stacie Herron‘s appointment permanent. Herron also serves as the company’s chief legal officer. 

“Tim brings proven financial leadership and a strong track record of collaboration,” said Keller Williams President and CEO Chris Czarnecki, who was just appointed to his position in March. “Stacie has already delivered meaningful impact as our chief legal officer and interim COO, and her official appointment as COO reflects our confidence in her continued leadership.”  

The appointments come after a shakeup in Keller Williams’ executive suite. Previous President and CEO Mark Willis stepped down from his role in January, about a year after returning to the position following a nine-year hiatus. He currently serves as chief leadership officer.

Before joining Keller Williams, Dieffenbacher served as CFO of FrontView REIT, a Dallas-based real estate investment trust that owns outparcel properties at shopping centers. Before that, he worked with Czarnecki at Broadstone Net Lease and Broadstone Real Estate. Dieffenbacher is a certified public accountant. 

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

Herron joined Keller Williams as CLO in March 2021. She later became chief legal and people officer, followed by CLO and chief administrative officer. Earlier in her career, she was an in-house corporate attorney at a NYSE-listed retail company. 

“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.”
