Marjorie Flannigan MacLachlan truly believes in the power of home and is passionate about helping others achieve their real estate goals. Known for her upbeat nature and dedicated attentiveness, she strives to make every transaction smooth and stress-free!

A born-and-raised New Yorker, Marjorie attended the City's High School of the Performing Arts, where she was a dancer, and went on to become a magna cum laude graduate of Georgetown University, where she earned both her undergraduate and law degrees.

Before entering the real estate field, Marjorie enjoyed a successful career as an attorney. She was a litigator with Simpson Thacher & Bartlett, one of New York City's most esteemed global law firms, for over a decade. She later served the Justice Department by overseeing compliance with a front-page tax matter. Along with advocating for high-profile clients, Marjorie dedicated her pro-bono efforts to landmarks preservation, an area she is still passionate about, having served on the boards of the New York Landmarks Conservancy and Friends of the Upper East Side Historic Districts.

Rooted in Marjorie's decision to become a broker is her conviction that her experience as an advocate and problem solver allows her to provide meaningful advice to people during watershed moments — the decision to buy or sell a home. All in a city she knows and loves.

As with her legal clients, Marjorie is truly "on your team" and works tirelessly to ensure you receive individualized attention, market education, and the due diligence needed to guide you throughout the process. She gets the job done while keeping things positive and upbeat. Marjorie works with first-time buyers, seasoned investors, estates, and everyone in between.

As a native New Yorker, Marjorie delights in offering recommendations for things to do and see throughout the city, from the latest ballet showcase to hidden parks and gardens few non-locals are familiar with. Her ongoing goal is to help others weave their own lives into the City's extraordinary fabric.

In her free time, Marjorie enjoys city life, family time, museum hopping, walks with her dogs, tons of reading, and the occasional foray into fitness (which also mainly involves reading).

For Marjorie, your sacred space is home.

"Your sacred space is where you can find yourself again and again . . . a place that lets you experience your own will and your own intention." — Joseph Campbell

“Marjorie brought fresh energy to the sale of our home, which, after a year on the market with a different company, was a ‘tired listing’ in a down market. Her excellent aesthetic enabled us to show off the best features of our Fifth Avenue apartment. Not only did she market the apartment creatively, she engaged prospective buyers in a way that invited them to see themselves living in the beautiful space and light that the apartment offered. At the point that an offer was pending, her genuine enthusiasm and astute negotiating skills made the deal happen. Marjorie is a highly talented and positive individual. She is a joy to work with.” - Susan M.

“I recently made my first home purchase, and Marjorie made the process as seamless and stress-free as possible. She was extremely knowledgeable, always available for showings, and able to answer all the questions I had as a first-time buyer. She was enthusiastic and excited, and clearly loves her job. Marjorie was able to guide me through the process and helped me when I was unsure about any aspect of the purchase. It was such a pleasure to work with her, and I recommend her without any hesitations!” - Sarah B.

“Marjorie handled the sale of my departed parents’ apartments with dedication, tactical brilliance, and finesse. She worked tirelessly to market the apartments in a down market and kept the family updated every step of the way. Marjorie is resourceful, quick-witted, and an excellent communicator. Her business savvy is matched by her emotional intelligence. She worked with our family — still mourning the loss of our parents — with thoughtful and caring kindness. It is a joy working with her. Marjorie has it all. She is my NY real estate agent for life.” - Alison W.

“As a first time home buyer, I looked for an agent who I could trust to be honest and forthcoming about any property that I was interested in. Thank goodness I found Marjorie! She was wholeheartedly invested in the process with me and guided me when I needed it. She told me when a property seemed overpriced in their maintenance fees and gave input on why she had reservations about a property. I needed her to tell me these things because I otherwise wouldn't have seen it if I was by myself. She is very responsive and works extremely hard to make sure she has done everything on her end to help you if there are any issues that arise during the purchase. Not only that, I really loved her friendly and warm demeanor. Her love for New York is inspiring and she transfers that same excitement to you. I loved working with her so much that I recommended her to a friend who was also a first time homebuyer. My friend loved working with her as well! Marjorie is the best! You'll be so happy she's on your side!” -Anna Q.

“My husband and I decided to take advantage of buying our home in 2020 during Covid. We contacted Marjorie and within 3 weeks she found us our dream apartment with the location, size and price we were hoping for. As most New Yorkers know, co-op boards are challenging to navigate. Marjorie saw us though that process beautifully. She worked closely with us, the selling broker, and the co-op’s management company to make sure all the information needed was gathered and presented in the clearest, most engaging, and professional manner. She kept us in the loop throughout and, in the end, made it easy for us to get approved. We love our new home and feel thankful to have had a broker like Marjorie guiding us through it all! - Judy C.
