Jill went over and above from the very beginning of our engagement. We have worked with dozens of real estate agents in the US, Europe and South America - we can’t recall anyone else ever to have personalized the rental and sale process. This was our home for over 15 years. Not only was Jill an amazing professional with spectacular attention to detail, but she also recognized that we were having a crisis. She took special attention to be patient and understanding with us while we deliberated on selling our home. Even after the contract was signed, there were numerous hurdles that had to be overcome. Jill eagerly volunteered to help us with inspections, tests, vendors and attention that was needed to close on the sale. Perhaps the best way to summarize Jill is that she did not treat us as a “client”, but we always felt like we were being treated like family. We will recommend Jill enthusiastically and without hesitation.

Jill is the perfect combination of calm presence and go-getter. She is so knowledgeable about the surrounding market and is a great resource throughout the process, including guiding us to great house stagers, painters, etc. Jill responds to questions right away, and always has a can-do attitude. We would recommend Jill wholeheartedly!

Jill is a true professional. I had her as my broker when I sold my house in Greenwich and would not have thought about using anyone else. Any issue that needed addressing, Jill either dealt with it herself or knew the appropriate person to call. She was on top of the selling and buying process from start to finish. I would recommend Jill as a broker to anyone looking to buy or sell.

Jill is the utmost professional. She is brilliant, thorough, and always looks out for my best interests. She has been my broker for three transactions, and I have witnessed much less qualified brokers. I recommend her in the highest possible way.

Jill was very professional throughout the entire process. She definitely knows the Greenwich market and advised me on a realistic asking price. She helped in every way throughout the entire transaction. Her knowledge of vendors to do the repairs needed helped a great deal. I would recommend Jill to anyone and I am looking forward to using her when buying my new home in Greenwich.

Jill is an excellent agent with outstanding knowledge of the property market. She is considerate and professional and supported us through all stages of our house sale, from staging to marketing to closing the sale. We could not have had a better real estate agent.

Among her many skills and experience, Jill possessed a keenly accurate market analysis that let us set a high bar for our asking price, and which turned out to be exactly the right number at exactly that moment in the market. We so appreciated her warm and gracious manner, and her willingness to help with every aspect of both selling and buying property. We cannot recommend her more highly!
