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.

Wendy is hands down the best real estate agent I have ever known. Her tremendous knowledge and professionalism extent to everything she does.

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.


Michael O'Brien
Broker

Sold (as lead agent)
Properties for sale
Buyer of 4597 Wildcat Lane, Concord
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.
