About me
Born and raised in Marietta, Georgia, Mary grew up in a real estate family where negotiating well and looking out for clients' best interests were regular dinner-table topics. She earned her real estate license in 2002 while at the University of Georgia, started working with buyers and sellers, and fell in love with the business herself.
Today Mary has helped individuals and families buy and sell more than 650 homes across East Cobb, Marietta and North Atlanta. She specializes in luxury homes and is known as a negotiation expert. Her goal is simple: make every client a client for life.
Mary lives in Marietta with her husband, Ben, and their four children, and she looks forward to the opportunity to serve you through real estate.
How I work
Buying or selling a home is a big deal, and I treat it that way. I'll give you honest advice about pricing and strategy, keep you in the loop at every step, and negotiate hard on your behalf. My goal is for every client to become a client for life.
