Kathryn and Kelly Mangel Know The New Trier Housing Market

When it comes to buying a home in the New Trier High School District, nobody knows the community quite like Kathryn and Kelly of Team Mangel with @properties Christies International Real Estate in Winnetka, IL.


As sisters-in-law who married brothers, Kathryn and Kelly share more than a family bond—they share a deep-rooted connection to the North Shore. Both are New Trier High School graduates, grew up in Wilmette, and now call Kenilworth and Winnetka home. They have been buying and selling real estate for over 22 years and have sold/purchased over half a billion dollars worth of real estate.


Their connection to the community is also personal as parents. Between them, they have six children who were raised in the New Trier School District and attended both public and private schools. This firsthand experience gives Kathryn and Kelly an invaluable understanding of the local school districts, educational options, programs, and opportunities available to families. They understand the questions parents ask because they've been through the process themselves.


From knowing the nuances of each neighborhood and school district to understanding the lifestyle and amenities that make each North Shore community unique, Kathryn and Kelly bring a depth of local knowledge that goes far beyond real estate.


Their lifelong roots, firsthand parenting experience, and genuine love for the North Shore make them the ideal team to guide buyers through one of life's biggest decisions.


They're not just selling homes in the New Trier community—they're part of it.

With Team Mangel, you're getting two dedicated real estate professionals, generations of local knowledge, firsthand school experience, and a family commitment to making your next move feel like home.
