Mike Petersen founded the group in 1992 after 10 years in the neighborhood as a homeowner himself. He knew every street, every school boundary, every block that flooded in spring. That knowledge has never been matched by an algorithm.
Kathy joined two years later, bringing an instinct for what makes a house feel like home — and a calm negotiation style that has saved clients tens of thousands of dollars over three decades.
Their daughter Sarah and son Tom grew up in Naperville homes their parents helped sell. Now they carry the tradition forward — same values, same phone number, same commitment to answering every call.
"We're not in the transaction business. We're in the family — moving business."
— Kathy Petersen
Mike and Kathy have been our neighbors for 20 years — when it was time to sell, there was no one else to call.

The whole family was involved. It felt like working with people who genuinely cared about us landing in the right home.

32 years of knowing this market means they saw our home's value that Zillow never could.
