Allison Ziefert

I co-lead a top-producing real estate team with my partner, Sarah “Ginge” Calhoun. We specialize in helping buyers and sellers across the Northern NJ suburbs—Maplewood, South Orange, West Orange, Millburn/Short Hills, Montclair, Morristown, Livingston, Bloomfield, Glen Ridge, and nearby towns—communities known for their character, strong schools, and proximity to NYC. With 500+ five-star reviews and a market-leading track record, our clients trust us for strategic pricing, high-impact marketing, and clear, confident guidance.

My listings consistently outperform the market, selling faster and for higher prices than comparable homes. Buyers rely on me to help them compete and win in an ultra-competitive environment. My prior career in construction project management, downtown development, and local government—along with degrees from Barnard College and Columbia University in Art History, Urban Planning, and Historic Preservation—gives me an uncommon combination of market knowledge, design insight, negotiation skill, and strategic thinking that directly benefits my clients.

Originally from Pittsburgh, I’ve lived in Maplewood and South Orange since 1995 and am deeply rooted in the community through Congregation Beth El and the Jewish Federation of Greater MetroWest’s Business & Professional Network. I’m an empty nester with three grown children, and you’ll often find me walking my dachshund, Archie, exploring local shops, taking fitness classes, cooking, or hunting for antiques. I genuinely love meeting people, understanding their needs, and helping them find or sell a home with confidence.

"As a first time home buyer who was unfamiliar with the NJ housing market, choosing Allison to work with us was the best decision my husband and I made. She was able to understand us and our needs extremely quickly and helped us every step of the way before, during, and after we became homeowners. Her and her team are very efficient and communicative. They are well regarded in the area and are experts when it comes to the market they serve. We wholeheartedly recommend Allison and her team and are so grateful she was able to help us find our little sanctuary. " - Samana B., Maplewood .

"I couldn’t have asked for a better agent — or a better human — than Allison at AtoZ. Selling the home where I raised my children and built a life over more than two decades was deeply emotional, and Allison guided me through the process with compassion, clarity, and skill. She didn’t just list the house — she took the time to understand it, and me. Every step, from perfectly timing the listing to managing showings and navigating offers, was handled with professionalism and care. The AtoZ team was equally impressive: organized, responsive, and genuinely kind. Allison was both an advocate and a strategist, helping me stay grounded and confident through a major life transition. She brings the perfect mix of heart and hustle — and it makes all the difference. If you're selling a home that means something to you — or buying one that will — you want Allison by your side. She's truly exceptional. " - Elena S., South Orange.

"Allison was absolutely amazing in helping our family find a home in a short frame of time. She was very well educated about the market and helped us to settle on a perfect home! Throughout the closing process she was very involved in all aspects and was there to assist us in anything we needed. She was extremely responsive and just an all around joy to work with! " - Madison B., Summit.

"Madison B., Summit My family and I recently moved to South Orange from Providence, RI, and we are so grateful to have found Allison and her team. From our very first call through closing (and even after), Allison guided us every step of the way with professionalism, warmth, and expert advice. Not only did she help us find the perfect home, but she also connected us with schools, inspectors, contractors, and even neighbors—making our transition to a new community so much easier. Allison’s tagline is “NJ from A to Z,” and we can confidently say she truly delivers on that promise. " - Jeffrey B., South Orange.

"The great thing about working with Allison is that you're getting a small, committed team that never overextends itself. You're not just another listing. You're not going to fall through the cracks because they're juggling 100 clients at a time. In other words, when your home is being listed, you're a total priority. That fact shone through in the promptness of communication we received whenever a question or concern was raised as well as thoughtful check-ins. And that prioritization paid off. Just start with a conversation and you'll see right away why we felt comfortable putting our faith in Allison. " - Christiane G.

"I met several realtors as I started the process to sell my home. I'm a divorced mother of 3, and after 10 years in our home was ready to downsize - but not without major apprehension and nerves. I told Allison I'd need hand-holding and she was there every step of the way. Her calm demeanor kept my anxiety at bay, and I genuinely felt I had a trusted partner and expert to lean on throughout. Allison was able to refer the teams I needed to organize, stage, repair, and get the most return out of my investment. I have recommended Allison and her team, and will continue to recommend them, to anyone I know looking to sell their home." - Rachael E.

"We used Allison to sell our house in Maplewood. Not only was she responsive and professional, she is a true pro at what she does. She knew exactly what we needed to do to get our house ready to sell - and then she sold it for WAY over asking. While we knew we were selling in a hot market, we truly feel that Allison and her team were instrumental in our getting multiple offers and so much money for our house. " - Marne F.


★★★★★
"Allison and her team were invaluable to helping us get absolute top dollar for our home. They had a plan, a network, a cheat sheet, and a team "on the ground" that helped us with everything from getting our home ready, to working through various inspections, approvals and township sign offs. With two little kids under 3, selling our home was a stressful proposition, but Allison understood and worked with us in the most efficient way possible. Our home sold in a single weekend for 20%+ over asking with multiple offers! Thank you, Allison!" - Jenna B.


★★★★★
"Allison and her team were fabulous to work with. We move every 5 years or so, whether we need to or not, so we've had our share of experience in the real estate market. Allison is a true professional, keeping the drama out of every interaction. She stopped us from jumping at the first offer, and added to our bottom line in doing so. We highly recommend!!!" - Julie V.

"When I say I appreciate Allison Ziefert and her team, I mean it. I didn’t realize that having a positive realtor experience was so unique until I moved and interacted with other realtors. Allison’s entire group is responsive, organized and helpful. I could rely on them to proactively keep the process moving forward which is such a relief, especially since I was out of state most of the time and it was during COVID. They minimized the stress of selling a home and shared valuable feedback at each stage. And I had a good experience working with each contractor that they recommended to help me get the house ready and move. Thank you to Allison Ziefert and team!" - Jerome M.

"Our family lived in Maplewood 20+ years - we chose Allison Ziefert to sell our 100-year-old home. At our first meeting Allison laid out her overall plan and candidly discussed any challenges and how she and her team would highlight our home’s strengths. From agreeing to list, to coming together on the asking price, to our final walk-through with our buyer, Allison and her team (Jaime!) were in regular contact with us and made the entire process (almost) easy (really!). Allison knows our community, she has a great team and strong local connections (painters, photographers and all the helpers) who made it happen without a hitch. We had so many offers well above our asking price and happily closed soon after we listed with Allison. Thank you Allison!!" - Lydia L.
