Brian, Jamaica Plain, a buyer from Jamaica Plain, MA
When searching for a real estate agent for my first home purchase, I received a glowing referral for Sean Callahan. From our first conversation, Sean was extremely generous with his time, speaking with honesty and integrity about his values in conducting real estate transactions, centered on building long-term relationships.

His expertise and attention to detail in assessing the quality of the homes we looked at was instrumental in this process -- he brought to my attention so many details I would have overlooked, and explained everything with great detail and patience. From our conversations, I learned a great deal about home construction and the home-buying process.

In all our dealings, Sean was kind, warm, principled, and knowledgeable. He was responsive and dedicated every step of the way, but never rushed or pressured me. He helped navigate some thorny negotiations with calm and grace, working through the closing process as smoothly as could be hoped. And he continues to provide care and assistance months after my purchase. I hope to work with Sean again.

I've worked with Sean to both buy and sell a property. He has always worked tirelessly at any time of day or night to get the job done, and done right. Would recommend to everyone. A+++++++++.

Mark, Southie, a buyer from South Boston, MA
Sean was fantastic and I'd highly recommend him to anyone in the Boston area. He was knowledgeable, patient, and went above and beyond what we would have expected to address our needs and concerns.

Raseeka O'Chander, Medford, a buyer from Malden, MA
I think a personal recommendation goes a long way. Sean came to us highly recommended.

I cannot emphasize enough how taken care of we felt by Sean. His attention to detail in helping us preempt and navigate every stage of the home-buying a home process was so helpful, and appreciated.

Sean is excellent with a capital E! And last but certainly not least, he is a genuinely nice and caring person.

Sean Callahan was the mastermind behind navigating two transacations at once (negotiating/buying our new home, before officially putting our home on the market, and then selling our current home: all within a 60 day time period). He provided guidance, emotional "gut check" support, and unfathomable expertise. My wife and I were so blessed to work with Sean and will continue to refer to anyone/everyone!

Tom & Diane Gauthier, Wilmington, a seller from Medford, MA
Sean, simply put, was truly wonderful. He was professional throughout the entire transaction. For me it was a emotional sale as it was my parent's home and the home of my childhood. I prepared the property for sale in memory of my parents and wanted to pass it on to a wonderful new owner who would love it and have wonderful memories as my parents and I did. Sean delivered a perfect buyer and we just found out that they were expecting a baby during the transaction as they shortly thereafter were blessed with their first child. How wonderful for them.
If there was an issue, Sean was there to resolve it. We had a lot of laughs. We had good conversations and he kept us up to date on all matters involving the sale. He was compassionate and sensitive to my feelings during the entire sale. For that I am grateful as that meant a lot to me.
We would definitely use Sean again for broker services. We highly recommend him.


Tina & Anne, Malden, a buyer from Malden, MA
Sean was incredibly transparent, kind, utterly not pushy, and super easy to work with. It became clear immediately that getting our priorities met was something that was genuinely his priority. His value assessment of properties is out of this world. He basically predicted what all properties we bid on would go for down to $500. His advice and guidance was essential to is making a lucrative winning offer without overpaying. Couldn't recommend him more.

Kyla Slavinsky, Cambridge, a seller from Cambridge, MA
Sean was truly wonderful during the entire process. This was my first time selling property and Sean's extensive knowledge and expertise played a huge role in calming my nerves and helping me understand the process. He was extremely professional, was always available to answer any question I had and consistently gave me updates on what to expect and of the timeline for selling the property. Sean also handled all the small details and I can honestly say that this was a stress free experience! I would highly recommend Sean to anyone who is looking to buy or sell a property. You won't be disappointed!

Jay Salazar, Vacaville California, a seller from Malden, MA
Sean took all the stress out of selling this property. He resolved issues as they came about and took extra time above and beyond to limit the anxiety I felt about selling the property. He was attentive and sensitive to our concerns, which made the process of selling the home comfortable and relaxing.

Selling our beloved home was a really emotional process for me, and Sean really helped me get through it, and helped me see the positives. Sean did everything he could to help throughout the entire process, and his demeanor and words of encouragement were always so helpful. I HOPE I get to work with him again!

Sean Callahan has been our real estate agent for many years now, and we have developed a solid trust in his abilities to assess properties accurately, communicate clearly, and always negotiate in good faith and with an honesty that never ceases to impress. He has guided us through the process of buying and now selling real estate and has always displayed a consistent duty to our best interest. Even when we felt that things wouldn't come together, he remained positive and focused on finding a house that we could truly make a home. In short, he is examplary in his profession, and will be a person we continue to turn to as we plan our real estate future
