Print Agent Bio

Marketing homes requires a great deal of experience and knowledge but more importantly it requires an agent who truly cares about customers and community.  Compassion, commitment and communication are three principles I strive for to serve in every listing, showing and sale.  I will provide you with the expertise and professionalism you expect from your agent.  

I've lived in my community for over 23 years and I understand our neighborhoods, how the community has grown and will grow further.  I use the experience gained to guide and serve my clients by leading the way in successfully marketing their homes. 

Why are you selling your home?  Why are you buying a home?  Whatever the reason, you need an agent who understands that buying or selling a home is an active process and makes that process worry-free.

My husband and I know many realtors. When we found ourselves with the task of selling not one, but two homes because of our parents passing, we asked Debby Hennessy to represent us. As a friend, I have admired Debby's compassion, humor, and work ethic for several years. We found all of that and more were part of her professionalism in working with us. In both cases she had to work with 3 siblings (total of 6) who lived from Seattle to Oakland. Her communication was detailed and constant. Many e-mails went back and forth of which she responded to in an informative and timely manner. My mother's house was in a neighborhood Debby had not worked in a lot so she brought in a realtor who knew the area well and helped price the home accurately. My mother's home needed much updating. Debby helped us focus on what really was needed to help sell the home making an overwhelming task much easier. She brought in an interior designer on Larry's father's home to help with colors. Debby even staged his home with her own furniture. Before open houses she would vacuum and dust to make them perfect. Not only did Debby contribute much of her time to sell our homes, but she also provided the sellers home warranty out of her own pocket. We can not thank her enough and would and have recommended her services gladly. Sincerely, Debbie and Larry Haroun

My wife and I would like to take this opportunity to express our appreciation for Debbie’s excellent job in representing us as sellers for our home. Her market analysis put our home in the perfect price range and we sold very quickly. We were impressed with her passion for selling real estate. We really enjoyed working with her and will continue to recommend her to our friends and family.

— Dean & Jennifer Wood

Debby Hennessey was fantastic during every aspect of our home sale and purchase. Her expertise and thorough understanding of the current housing market helped us sell and purchase with confidence and peace of mind. We would highly recommend Debbie Hennessey to anyone desiring a realtor that will consistently exceed your expectations in all phases of the buying or selling experience.

"Debby Hennessy is an incredible agent. When we put our house on the market, she went above the call of duty in trying to help us sell our home. She would swing by the house working thoroughly to make sure the house was always in its most presentable state. She represented our interests, and she made sure to be available. Debby is truly the best. I would not hesitate in working with her again. If you are looking for an agent who will give you 100%, Debby is your person."

"We moved here from NY, wanted to rent for a year to get to know the neighborhood. We attended open houses until we were ready to be a serious buyer. We ran into Debby at two of the open houses and were so impressed with her as a salesperson. Just the right balance of knowledge, pointing out things missed without being pushy. We asked her to be our realtor to find our forever home. She was amazing, we were a specific and unique homebuyer, not looking for cookie cutter home and she had the utmost patience with us. When we found a house that we were passionate about she was a tremendous help in the negotiations, thought outside the box when we couldn't get an agreement right away and had great connections to finding the best inspectors and contractors for bids. My other favorite thing about Debby was her communication, always prompt and thorough. Without a single reservation I would recommend her to anyone, a complete professional, a joy to be around and totally in your corner."

"I recently listed (and sold!) my home using Debby. Debby uses a team approach with a staging consultant who really made my house pop. She then set to work creating as much interest as possible in the home and generated several above price offers. She worked with me to understand the net payout to me, steps required to closing and state of the market. All along, she was great at keeping me informed of developments and worked very hard to get my home sold and closed as well as getting me the best price all during a terrible time in the market. I would highly recommend her."
