She works with an equally talented team of agents, lenders and vendors to ensure her clients are getting the best care and best deal when buying or selling their home.

“Catherine came highly recommended and exceeded all expectations. Catherine combined her extensive knowledge for real estate then added a very personal but professional touch to our open houses. Catherine sold our home at an open house over the asking price. I highly recommend working with Catherine.” ~ Client Review

“Wow! We can’t say enough about Cat and our home selling experience. She knew the market and helped convince us that this was the right time to sell our property. We gave her a small time frame and were firm on getting our sale price. She went above and beyond during the process, answering countless (silly) questions at all hours of the day and night. She made herself available 24/7, gave productive feedback, and was there every step of the way!! Even the neighbors noticed she was at the house literally every day. We were selling from several states away and she made herself physically available when we couldn’t be present during inspections and so on. We are so thankful for her hard work and commitment. She truly loves what she does and it shows!” ~ Client Review

“Catherine was able to find my husband and I a condo last year and she never let us get discouraged or frustrated in the process. We knew we wanted to live within a certain area which was challenging with our budget. However, she ended up finding what would become a great home for us while my husband was stationed in the area and I was finishing graduate school. We have grown to love New England and look forward to working with her again in the future. She is simply the best at what she does!” ~ Client Review

Catherine was fantastic and stuck with me for over a year from California to my move back home to New Hampshire and I couldn’t be more thankful. She is very helpful and motivating. Catherine is always there when you need her and very friendly and personable and will fight for you to help.” ~ Client Review

“From start to finish, she was more than helpful and super communicative; quick to respond, answered all our crazy questions and made sure we knew what to expect throughout the process. As first time home buyers, there was a lot we didn’t know about; but she was a phenomenal guide and gave us the support and assistance we needed to get through to closing. She really had our backs, even when we hit a few road bumps along the way. Catherine helped us to find our dream home and we just couldn’t be more thankful. Highly recommended and wonderful to work with!! Thanks again!!!” ~ Client Review

“We loved working with Catherine as we purchased our first home! She was great in helping us find the home that we were looking for-she really listened! She took good care of us from searching to closing and we’d highly recommend her. Thank you, Catherine, for being honest, professional and helpful!” ~ Client Review
