Experience the Difference

As the Managing Broker for the Dunwoody Office, I take pride in creating a productive atmosphere that allows independent agents to approach their activities with creativity and a positive attitude. I strive to assist each agent to achieve their business and personal life goals.

The Coldwell Banker Difference

Today’s real estate market is becoming more sophisticated and challenging and you need a Broker that not only understands the industry, but has excelled in it. I was a top agent in the #1 office in the city and know how to be successful in this business. From giving newly licensed agents access to a solid foundation upon which they can build their business, to giving seasoned agents access to advanced education to continue to grow their business, I am passionate about my position as Managing Broker and sharing my knowledge and enthusiasm with each of the agents in Dunwoody.
