About Mary and Michelle

We are excited to share with you the joined forces of Mary Gillespie and Michelle Pappas. Together we have over 18 years of real estate experience in the Northern Virginia area.

Our aligned goals of wanting our clients to love working with us drives so much of what we do.  Please take a look at our testimonials.  We think you will find that our clients agree we have the core qualities that make us great realtors:

  • Experience

  • Strong work ethic
