About Sarah

As President of Terrie O’Connor Realtors, Sarah M. Drennan wears many hats—strategist, motivator, coach, occasional magician—and oversees the operations and growth of nine thriving offices and more than 450 sales associates. A licensed Real Estate Broker with a background in public relations and a knack for making things happen, Sarah leads with equal parts vision, drive, and good humor. Before taking the helm, Sarah served as Executive Vice President and previously managed the Allendale office, where she was known for turning potential into performance and coffee into closed deals. Her earlier career included roles as an International Resource Manager at one of the world’s largest PR firms and as a founding partner and VP of Operations at a public relations trade association—where she learned how to diplomatically herd very ambitious cats. Her transition into real estate was as seamless as her negotiation skills, blending experience in marketing, sales, and customer service into a leadership style that’s sharp, supportive, and just unconventional enough to get results. Sarah currently serves on the Board of Directors for the New Jersey Multiple Listing Service and has held multiple committee positions with Greater Bergen Realtors, proving that she doesn't just talk about raising industry standards—she shows up and does the work. Outside the office, Sarah gives back as a board member of The Grace Foundation of Terrie O’Connor Realtors and supports organizations like Covenant House of New Jersey. She’s also a twice-elected Councilwoman for the Borough of Upper Saddle River—because apparently running a company and raising three kids wasn’t quite enough.

Exceptional Guidance - The Realtor you want in your corner!

Selling our family home after the loss of our parents was an emotional and complicated process, and we could not have asked for a better realtor than Sarah Drennan. From our very first meeting with Sarah at the house, it was immediately clear she was exceptionally knowledgeable, experienced, and capable, as well as compassionate. Sarah guided my brothers and me through every step of the process. She recommended outstanding estate sale companies as well as a highly skilled moving company experienced in handling fragile antiques and sentimental items with care. Her strategic advice regarding pricing and evaluating offers was invaluable and gave us tremendous confidence throughout the sale. What truly set Sarah apart was the amount of work she handled behind the scenes. When she realized I was overwhelmed with other responsibilities, she stepped in and personally handled obtaining the Certificate of Occupancy and Fire Inspection on my behalf. She consistently kept everything moving forward and worked tirelessly to help resolve title issues that unexpectedly delayed the closing indefinitely. Sarah communicated directly and proactively with the buyer’s agent and our attorney, Chris, whom she had recommended, and in doing so kept me informed in a way that facilitated and expedited resolution of the issues that had arisen. In an especially impressive effort, she even contacted another title company she and Chris had previously worked with to learn how they would approach the issue we encountered. That insight ultimately became the key to resolving the problem and getting us to closing. Sarah went far above and beyond what anyone could reasonably expect from a realtor. Her professionalism, dedication, resourcefulness, and compassion made an incredibly difficult process manageable. I recommend her without hesitation.
