Mark was a referred agent and helpful from start to finish. He was direct and available whenever communication was needed. Overall quick selling process, knowledgeable, and had my best interest. Would recommend and use in the future. Thanks, Mark!

-Julia Baumann, Client

Mark was very helpful and responsive through the selling process. He was eager to help us get the home sold and could definitely be relied upon to answer questions or address concerns in a very timely manner. I enjoyed working with him through this process.

-Angelika Brannen, Client

Mark is an excellent negotiator. The home we wanted had 8 other contracts but he was persistent and skillful in making sure we got it. Mark understands the market and has great relationships with other realtors, which is invaluable in helping his clients. He’s extremely responsive and is great at explaining the buying and selling process. Mark also gave us great advice …

Mark sold our house fast! He was great to work with and very professional. We would definitely refer him to others who want to sell their house. Selling a house is stressful, but Mark made it easy!
