Cathy Hertler was the listing broker for my home in Billerica. Working with Cathy was great. She was very proactive about setting up meetings to get the process started. She was knowledgeable about the area and the market and gave me realistic expectations for sale price. She was very generous with her time setting up multiple Open Houses during the difficult end of year holiday season. I would be happy to recommend Cathy as your real estate agent.

I just recently moved to Billerica in January of 2014 with the intent of going from a apartment to a house, after a year of being here. My mother passed away in August and knowing my father was coming to live with me I had to move quicker then expected. I walked into the Real Estate office explained my situation and Cathy was outstanding from the word go. She made sure to be on call and always responded with a answer to any question or concern I had.

Cathy really outdid herself getting this property sold. She helped me get rid of extra furniture in the home, provided me with great suggestions and didn't give up when things looked grim. Anybody with a tough to sell property should work with Cathy.
