About Us

As high school sweethearts turned business partners, we’ve built our lives and our careers right here on the Main Line. Today, the Collin + Colleen Whelan Team is proud to call Wayne, PA home while helping buyers, sellers, and investors throughout Radnor, Villanova, Bryn Mawr, Devon, and the surrounding communities.

Our background in general contracting, construction management, interior design, and staging gives us an edge that most real estate teams can’t offer. From preparing a home for sale to evaluating new construction opportunities, we bring both local knowledge and hands-on expertise to every transaction.

Our Commitment to You

We know the Main Line because we live it every day — raising our daughters here, volunteering locally, and investing in the same communities where we work. Whether you’re purchasing your first Radnor home, upgrading to a luxury property in Villanova, or considering a new build in Wayne, our role is to guide you with honesty, clarity, and care.

With Compass’s industry-leading marketing paired with our construction and design experience, we help clients unlock maximum value while making the process as stress-free as possible. Real estate isn’t just about houses — it’s about people, families, and creating lasting relationships.

If you’re ready to buy, sell, or invest in Main Line real estate, we’d love to be part of your journey.
