Catherine's Sold Homes LINK

  • We have been completely satisfied with Catherine's services. She is not an agent that lists your home and sits back and waits for something to happen. Catherine is very thorough, does the research, chases leads, puts time and effort into getting the house ready to show like something from a  magazine which is something most Realtors don't do. She was in constant contact with us throughout the whole process and a pleasure to work with.

    a pleasure to work with ...
  • Catherine was a real life saver. I needed to sell and buy a new house in a limited time frame. This was a very anxious process for me. If I didnt have Catherine Im not sure I would have been able to get through it. From the minute I met her I was impressed with her professionalism, knowledge,  energy, and enthusiasm for her job. However, she was still personal in her interactions with me and knew the stress I was under. She went above and beyond what I ever expected from a realtor. I have...

  • My wife and I were very fortunate to find Catherine through one of her listings. After that first home showing, we knew her personality and enthusiasm were a perfect fit. As we were selling a home locally it was an easy choice to list our home and find a new place both with Catherine’s guidance. Our home was redecorated in preparation for sale from top to bottom, Catherine’s and her team did an amazing job. Her market analysis was right on and our home sold quickly.
