After living in our home for more than 40 years, the decision to sell felt overwhelming. It wasn’t just a transaction for us—it was the closing of a chapter filled with memories. From the very beginning, Heather Donovan understood that. She guided us through each step with a steady hand, a warm heart, and a level of professionalism that immediately put us at ease. Heather consistently went above and beyond. Her deep experience in real estate was evident in every conversation, every recommendation, and every detail she handled. She brought an impressive network of trusted professionals to the table, ensuring we had the right resources to prepare our home for the market. What could have been a stressful process became manageable—and even reassuring—because Heather knew exactly what needed to be done and how to do it well. Her communication was exceptional. She kept us informed, followed through on every commitment, and navigated negotiations with skill and confidence. We always felt she was advocating for us with integrity and expertise. Looking back, we can’t imagine going through this transition without her. When the time comes to buy or sell again, Heather will be the first person we call.

834 Deer Spring Cir Concord
We interviewed multiple agents when we decided to sell our home. Wendy separated herself from the others with her professional demeaner, comprehensive presentation, and compelling track record. More importantly we were impressed by her attention to our needs and heartfelt commitment to doing everything she could to help us navigate this important and complex process. We felt an immediate connection to her. The marketing package that she and her team developed was outstanding and highlighted our home magnificently. Shortly after listing, the national economic environment became unstable, and it quickly depressed home sales. During this difficult time, Wendy helped us manage our expectations, revisit our original strategies, and ultimately sell our home. While the market turmoil took everyone by surprise, Wendy helped us through it all. In the end, we were very pleased with the outcome and our decision to work with Wendy. Her professionalism, dedication, and expertise came through when we needed them the most.

Wendy was the best realtor we could have possibly asked for! She is very accessible and responds swiftly. Just a text or phone call away and she’s at your service, ready to answer any question you may have. When our dream house hit the market, she acted fast! She made the process seamless and provided us with everything we needed to make an informed decision as first-time home buyers. She is extremely personable and working together was a joy! She truly makes you feel comfortable as if you’re working with a family member. You can tell that Wendy is well respected in her field, and can help you benefit from all her connections. We are so thankful that Wendy was recommended to us, she really is the best!

Working with Lilli as my seller’s agent was an absolute pleasure. She was attentive, knowledgeable, and truly understood both the area and the current market. From the start, she offered thoughtful suggestions on what updates would make the biggest impact and helped me focus my time and energy where it mattered. Any time I had a question or concern, she was quick to respond and always made me feel supported throughout the process. Her guidance was spot-on, her communication was excellent, and her calm confidence helped make a normally stressful experience feel smooth and manageable. I’m grateful for all the care and expertise she brought to the sale of my home, and I would 100% recommend Lilli to anyone looking for a knowledgeable, reliable, and genuinely committed agent.

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.
