Seller of 12 Wellesley Street, Medford
After a long and sometimes challenging real estate journey, I cannot say enough positive things about Kelly Catallo from Cosmopolitan Realty. From start to finish, Kelly was dedicated, professional, and worked extremely hard to ensure the transaction was completed within the required timeframe. She went above and beyond, working closely with the state and attorneys to keep the process moving forward and to resolve every obstacle that arose. Her persistence, attention to detail, and commitment truly made the difference in successfully closing this deal. I am incredibly grateful to Kelly and her entire team for their outstanding effort and support. Their expertise and dedication made what could have been a stressful experience a smooth and successful one. I highly recommend Kelly Catallo and Cosmopolitan Realty to anyone looking for a reliable and hardworking real estate professional.

Seller of 2/124 Harvard Street, Medford
I cannot recommend Mary highly enough. When my property didn’t sell immediately, many agents might have lost interest or simply suggested dropping the price. Not Mary. She got creative with her marketing approach, explored new strategies, and brought fresh ideas to the table at every turn. Throughout the entire process, she gave 100% effort—her dedication and energy never wavered, even when the market was challenging. When we finally got to closing and things became a bit complicated, Mary handled everything with professionalism and persistence, making sure we got through it successfully. She’s the kind of professional who truly goes above and beyond for her clients, and I’m grateful to have had her expertise on my side. If you’re looking for an agent who will fight for you from day one until closing, Mary’s your person.

Molly was a wonderful real estate agent for the sale of my home! She was extremely organized throughout the whole process; taking initiative and thinking ahead with all that needed to be done. She was responsive to issues that came up and super supportive of any questions or concerns that I had. Her calm and professional demeanor made the stressful process of selling a house much more manageable. I highly recommend Molly!
