This property was marketed as a diamond in the rough. Angela worked hard to show all the benefits of the 70+ year old house and how it could become a fantastic property for the right buyer. She was very communicative and action oriented. I would work with her again on my next property.

Angie was fantastic to work with on both a logistical and human level. She really understood what we wanted, communicated at all times and made us feel relaxed and taken care of. She also had great team of referrals for staging and preparing the house for sale. We had a short window of time to get the house on the market and she was amazing in making that happen in a painless way. We are grateful for all of her help throughout the process of selling our house and highly recommend her.

Angie was so much more than we could have ever expected. Here attention to detail was perfect and we could never dream of using anyone else.

Michael Moore was very professional and knowledgeable with all aspects of the sale of our property. He advises of market trends and kept in contact with us on a virtually daily basis, the entire time our property was on the market.

Having Michael as a realtor was a great experience. He was knowledgeable, respectful, punctual and accessible. all of which made our transaction go very smoothly. I would have no qualms about recommending him to anyone.

A true professional! Michael is rare in the sense that he has perfected the art of listening to his clients and can offer unparalleled wisdom from his vast history of experience. As I have been out in the field, everyone seems to know and like Michael! From people involved with 1031 exchanges, the title office and other realtors, all have high regards for him. He also almost always answers his phone, and if he is in a meeting, will get back to you the same day, the same with email messages. Hard work and true dedication to his craft is what you will get with him.Whether you are a seller or a buyer, he has got you covered. We are fortunate that he is helping us with both! Thanks Michael!

The experience we had with Debbie is unmatched! At no time did we ever feel pressured to make a deal. We explored many different options that fit our living structure and expectations. Debbie was mindful and helpful every step of the way, from showing us different options in and around the areas we liked to using her expert connections to finding us off market deals. When it came to closing on our purchase she knew exactly how to navigate those waters. Debbie got us a great deal on a great house. I HIGHLY recommend Debbie to anyone looking for there next real estate purchase. From fix and flip to a forever home, Debbie has the know how for it all.

Debbie is very knowledgeable. She goes above and beyond to help you. Her years of experience made me feel confident to have her as my agent.

Deborah is truly amazing.. She made the home buying process fun and easy for us. She is down to earth, honest and reliable. 10/10 will always recommend.

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.

Michael was a great help during our first experience buying a home. He was responsive and guided us through the whole process. 10/10!

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!!
