About Mary Ann

There are many qualities and skills that go into being an excellent real estate professional - integrity, in-depth community and market knowledge, marketing savvy, effective negotiation skills, and a high-quality professional network, all of which are hallmarks of how I work.

That said, in Mary Ann Sullivan’s experience as a Naperville, Aurora, Lisle, Plainfield, Oswego, Wheaton, Downers Grove, Woodridge, and Bolingbrook real estate professional, she found that providing the very best service is about putting her clients first. This means keeping herself accessible, being a good listener as well as a good communicator, and responding quickly to your needs.
