I highly recommend Maria Fernanda. She was our realtor when we purchased our first home. We took our time finding our dream home, and she was very patient with us. She always showed us the current listings, selected the best neighborhood, and found houses that matched our requirements and expectations. She is always available to answer any questions you may have during the process and even after the purchase is closed.

Working with Mike O’Brien was one of the best decisions I made during the home-buying process. From day one, it was clear that Mike genuinely cares about doing the right thing and truly representing his clients — not just closing a deal. Mike was honest, detail-oriented, and relentlessly attentive throughout the entire process. He took the time to understand what I needed, communicated clearly at every step, and never once pushed me in a direction that didn’t feel right. His integrity stood out immediately — he advocates for his clients as if it were his own money, his own home, and his own future on the line. What separates Mike from other realtors is that he leads with values. He doesn’t cut corners, he doesn’t play games, and he doesn’t disappear when things get complicated. He shows up, he protects his clients, and he makes sure everything is done the right way. If you’re buying a home and you don’t use O’Brien Real Estate, you’re making a mistake. Mike O’Brien is the kind of realtor you want in your corner — knowledgeable, trustworthy, and fully committed to his clients from start to finish. I couldn’t recommend him more highly.

We engaged Michael during a difficult time for our family. We were in an unexpected position and needed to find a new home that could be multi-generational in a short time frame. Our listing time last fall was during a challenging time of year. Through his advice and guidance we withdrew the listing before the Holidays, with the plan to re-list it in February. Because of his knowledge of the market and the strong relationships he has with other Realtors, we were approached prior to re-listing with an interested buyer. We were able to sell without having to fully go back on the market which exceeded our expectations! We can't say enough great things about Michael's professionalism, care for his clients, and the trust we had with him every step of the way!!
