Colleen Sullivan worked with my wife, Amanda, and I on two transactions. She sold our home for near asking price, and worked hard for us purchasing our new home. Colleen worked with us almost every day for six months making sure both transactions went smoothly. We would recommend her for any real estate needs! She was the difference between anxiety and angst and both deals going smoothly and professionally. Thanks, Colleen – John and Amanda Savage
