Extremely uplifting and positive

Sean is an amazing realtor, he was very professional, kind, punctual, helpful, trustworthy and honest. He had all the answers to any of my questions or concerns. He did an excellent job of marketing the property and drawing people into the open houses. He was very successful as he was able to lock us in after the first weekend of open houses. I highly recommend Sean K. Connelley to anybody who is looking to sell their home. He is extremely welcoming and friendly and makes you feel very comfortable and positive throughout the whole process. I will definitely be using Sean in the future when I’m ready to purchase or sell my next property. Thanks again Sean couldn’t have done it without you!

Absolutely amazing professional prompt explanatory

Sean Connelly made something happen for me and my son that we didn’t think was going to be possible! He deserves an award of some sort he has patience he explained everything to us he answered any questions at any time he was there throughout the whole process! I cannot recommend anyone other than Sean and his coworker Roberta was amazing also! The day before the closing my son met with him face to face my son was so appreciative of all his hard work and dedication to us that when he saw him he had to hug him it was an amazing and smooth sale! I highly recommend Sean Connelly and his associates! Thank you for everything!!!

Thorough in all aspects of his job.

Thorough in all aspects of his job.

When I first met Sean he showed up with a folder of research on my condo, the complex and current market. It wasn't just a friendly meet and greet he had done his homework. I was happily impressed not only with that but with his approachability more than willing to explain anything I had a question about. I also very much appreciated that I mostly communicated with him and his associate Kaylan

Sean is the Best

Sean is the Best

I have known many realtors in my 76 years and I must say that working with Sean Connolly in the process of selling 2 properties in 2025 and buying one— was just about as smooth and seamless as it gets. His professionalism and high standards are very apparent. But what I enjoyed the most was his candor and warmth. He actually cares about doing the very best for his clients. As a result of working with him, I am now living in my dream space in a wonderful location in Marblehead and it’s all because of Sean

In A League of His Own

In A League of His Own

I have never worked with someone whom I feel more confident recommending. Sean Connelly is an absolute gem of a realtor, and truly in a league of his own. From start to finish, he was intensely professional, incredibly knowledgeable, and consistently went above and beyond to protect my interests throughout the entire home-buying process. Sean sets the bar for what a high-quality luxury realtor should be. His communication is exceptional — proactive, clear, and always timely — which made the experience smooth and stress-free. On top of that, he’s genuinely fun to work with, bringing both confidence and ease to what can otherwise be a very overwhelming process. If you’re looking for a realtor who operates at the highest level, advocates fiercely for their clients, and delivers an outstanding experience, I cannot recommend Sean Connelly highly enough.

Trusted, Reliable, Results-Driven and a Pleasure to Work With

Working with Sean Connelly was a truly outstanding experience! I first worked with Sean three years ago when we bought our house, so when it came time to sell my condo, he was a natural choice. I had a firm closing deadline, and Sean worked diligently to ensure we met it. He priced the property appropriately and skillfully negotiated with the buyers to improve their offer—getting me the best outcome. Sean is a fantastic communicator and kept me informed at every step. He also took care of countless details behind the scenes, saving me a great deal of time and effort during an already busy period. Sean’s professionalism, strategic mindset, and calm, reassuring approach made the process smooth and successful. I’m grateful for his support and would wholeheartedly recommend him to anyone looking to buy or sell their home.
