Buying or selling a home is a complicated process and one of the biggest decisions you’ll make during your lifetime. I’m here to help guide you through the peaks and valleys, twists and turns, in order to help you reach your real estate goals and leave you smiling with joy after closing.

As an experienced Realtor, I communicate honestly and frequently with my clients to develop the best strategy for your home buying and selling needs, keeping you apprised of the important details and stages throughout the process.

I provide white-glove service from the beginning of the search, all the way through closing and even afterwards, when you may have questions like, "Where can I find a good electrician?" or "Where’s the best pizza in town?"

We had a fantastic experience with Mike working to buy our first house. Mike gave us all the information we needed, was incredibly responsive and always available to answer questions. He made it easy to navigate our search conditions and help us get into our house. Mike is a pleasure to work with!

Mike went above and beyond with our quest. We had a narrow scope and he was there to answer our most inane questions. Eventually guiding us to our current home (just 5 minutes from our old house. He was a pleasure to work with and I would recommend him highly to anyone searching for a home in MA.

Mike O'Brien was an amazing realtor that went above and beyond to help me find my new own. After having multiple discouraging experiences with realtors, he was a breath of fresh air that told me finding my new home, in the area I wanted, was possible. Not only did he support and help me find my new home, in my ideal area, he marketed and sold my existing condo in one of the fastest turn arounds ever. He went above and beyond to make sure I was comfortable with the process from start to finish, and responded quickly to my many many questions. I highly recommend him for your realtor needs and know I will for sure be using him again when real estate needs arise!

Mike O'Brien is an outstanding realtor. Mike helped me sell my brother's condo from another state. He went above and beyond in coordinating all that needed to be done to put the property on the market. He was right on target what needed to be done and what things future owners would probably want to decide for themselves. Mike communicated with me through the whole process and was always available. My brother sold his condo for more than we ever imagined. I highly recommend Mike O'Brien.

Mike did a great job for me. He walked me through the process and got me a great price for my condo. I wouldn't hesitate to recommend him. He could not have made the process any easier. Process was very easy.
