CHRIS LAMBROU
INTERIM CHIEF EXECUTIVE OFFICER

ABOUT ME

Chris Lambrou currently serves as the Interim CEO of Metro MLS in Milwaukee and has more than 26 years of experience in the multiple listing service industry. Since joining Metro MLS in 2016 as Chief Information Officer, he has led the organization’s modernization efforts, driving technological innovation and optimizing internal operations. In April 2025, he was appointed Interim CEO, where he continues to champion a service-first, results-driven approach to leadership.

A recognized thought leader in real estate technology, Lambrou played a key role in the founding of MLS Aligned, a strategic collaboration of six forward-thinking MLSs. He spearheaded the development of Aligned Showings, a modern scheduling platform now serving over 150,000 users nationwide. For his forward-looking contributions, he was named a 2025 RISMedia Newsmaker “Futurist.”

Lambrou’s influence extends beyond Metro MLS. He chairs workgroups for the Real Estate Standards Organization (RESO) and the Institute of Electrical and Electronics Engineers (IEEE). He serves on the Customer Experience Advisory Board at the University of Wisconsin–Parkside. His passion for improving user experiences in real estate technology has also made him a sought-after speaker at events such as Inman, CMLS and RESO, as well as at academic institutions including Northwestern University, New York University, Marquette University and MIT.

Outside of tech, Chris is an accomplished musician, a baseball enthusiast, and, most importantly, the proud father of two. He lives by a guiding principle: surround yourself with good people in an open environment and success will follow.
