"Jan is an asset to your company Cornish and Carey. She worked hard to help me with my first home and she negotiated hard with the sellers to accept my offer below the list price. She always took the time to listen to me and answer all my questions no matter how trivial. She attended every inspection and negotiated with the sellers to pay for repairs needed. Jan’ business card states that she won an award for excellence. I know now how she earned it." Christine G.
