What Clients Are Saying

Margaret O'Sullivan was by far the best agent we have ever had. She brought her A game from day one and completed the sale with some major roadblocks without hesitation. Margaret and her team were amazing and can not recommend anyone better.

Hire Margaret O’Sullivan. Just do it and I promise you it will be the best decision you make in the complicated process of buying and/or selling your home. We met Margaret 5 years ago, when she sold us our very first house. She worked tirelessly on our behalf and gently encouraged us to look in  towns that would appreciate when we needed to sell (perhaps foreshadowing we would outgrow that house 5 years and 2 kids later). This year, we hired Margaret again. She promised us she would go to bat for us at every turn and WOW, did she. The week we were set to list, the COVID19 pandemic hit and the world turned upside down. We paused on listing amidst the uncertainty and Margaret was supportive every step of the way. We stayed in touch and a few months later, we decided to list. She sold our house in one weekend, with multiple offers, at well over our asking price. On the buy side, because of the pandemic and the record low interest rates, the market was dizzying. We were starting to lose hope but Margaret never wavered that she would find us something great. Today, I write this review from my beautiful new home that never would have been possible without her. The outcome could not have been better. Margaret believes in ethics and hard work and it shows in everything she does; from her unending hustle on behalf of her clients to the high quality people she partners with (through her we found a fantastic interior designer, a great painter, a top mortgage lender, a moving company, our lawyer, the list goes on). If you want someone you can truly trust to handle every bit of this process, Margaret O’Sullivan is unmatched in the industry.
