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.

Hello my name is Paul Ivory

Hello my name is Paul Ivory

Hello my name is Paul Ivory.. I served as co-executor to my mother's estate which; of course involved the sale of her house and property. To complete this task I had the good fortune to be able to work with Terrie O'connor realtors and specifically with their representative Sarah Marie Drennan. What immediately strikes you about Sarah is how knowledgable focused and personable she is. From listing to closing everything moved smoothly and speedily. There was never a point in the process where I felt the need to question Sarah's insights and instincts. 24/7 she was available to address any questions or concerns I might have and always left me with the feeling that I was her #1 client. I would feel confident recommending her to friends and family. Sarah thank you for all the time and hard work you put in. I wish you all the best.

Sarah did a great job handling the sale of our home from listing to closing

Sarah did a great job handling the sale of our home from listing to closing. As expected our home sold very quickly. She advised us every step of the way explaining our options listening to our needs and ultimately guiding us to the finish line. I would recommend Sarah to manage your home sale in a heartbeat. Should a referral request come my way I know who's getting the listing!

10/10 realtor experience

10/10 realtor experience. We were able to close in under 30 days due to Sarah's wide array of home buying skills. Place we were able to secure wouldn't have been possible without Sarah's help. Within our price range and in the area we wanted. No settling with Sarah….she goes above and beyond in everything she does.
