ZillowVERIFIEDDeirdre and David have been amazing to work with throughout the home buying process process. It took us over 2 years to find and close on our home and they were patient throughout the entire journey. We are first time home buyers and their huge network of experts came in handy when evaluating the several homes we put offers on and understanding the expected costs. David's market comparison evaluation was also super helpful making us feel confident in the offers we put in. I would recommend Deirdre and David 100x over and couldn't have done this without them as they went above and beyond!! They went to the Marin country permit and tax office to confirm house details that weren't in the disclosures, had an inspector do a verbal inspection on the house within a day, and an HVAC person fix the heater before we moved in. If you're looking for a great real estate team, work with them!

ZillowVERIFIEDDavid and Deirdre have been a pleasure to work with since the get-go. They have been graceful with us - it was our first house, so we had a LOT of questions and needed a LOT of explanation. Throughout this whole process, not only they were extremely available and responsive, but they always went above and beyond to ensure we were set up for success! They negotiated our offer with patience, and always made sure we were in the loop. Thank you team O'Brien for finding us our new little nest.

ZillowVERIFIEDMy husband and I had an exceptional experience working with Deirdre and David to purchase our first home. From the very beginning, Deirdre invested time in truly understanding our needs, patiently explaining the entire home-buying process, and preparing us for potential hurdles in the closing process. Both she and David were incredibly informative and transparent, offering honest insights into the pros and cons of various homes and neighborhoods. They consistently led with integrity, offering thoughtful solutions and next steps for every challenge. With them, no obstacle felt insurmountable. Beyond their professional expertise, Deirdre and David were a source of emotional support and rational guidance whenever we felt stressed or overwhelmed. Buying a first home is a big decision, and having their steady presence helped us stay focused and confident throughout the journey. One of the standout aspects of working with Deirdre and David was their negotiation expertise and market knowledge. Thanks to Deirdres strategic approach, we were able to save around $100,000 on our home! Her skill in navigating the market with a customer-first mindset demonstrated her depth of experience and dedication. Once we entered into contract, they made the inspection process seamless by scheduling all necessary inspections and being onsite to answer any questions and troubleshoot. With Deirdre and David by our side, we felt confident and well-supported in every decision, knowing we were making an informed choice. Amazingly, within less than three weeks of working with them, we found our home, and our offer was accepted. We are beyond grateful for Deirdre and Davids hard work, professionalism, and guidance. Thanks to them, were now thrilled homeowners, excited for this new chapter in our lives. We wholeheartedly recommend them to anyone looking to buy or sell a home!

ZillowVERIFIEDWe were consistently impressed by their dedication, from the late nights spent working on contracts and viewing properties to the valuable advice and perspectives they both provided. It was incredibly reassuring to know we had such a strong team in our corner. Deirdre was incredibly patient and dedicated when showing us homes. She really listened to our needs and, in the end, helped us find the perfect place. Her commitment made all the difference. Davids extensive knowledge of properties, neighborhoods, and network were invaluable. He always had our best interests at heart. With both Deirdre and David guiding us, we felt confident in every decision we made. We will definitely be referring Deirdre and David to our friends and family. After spending so much time with them searching for our home, my husband and I often find ourselves missing our new friends. We look forward to staying in touch!

ZillowVERIFIEDDeirdre and David O'Brien were a dream to work with. Not only are they super knowledgable about properties in Marin county, the time they spent with us and the warmth they showed us let us know they really cared that we find the right house for us! We met with several other realtors, and when we met Deirdre, We knew she was who we wanted to work with! We are so happy with our new home thanks to both Deirdre and David O'Brien!
