MEET Antoinette
SULLIVAN
Her approach is simple:
Service first. Strategy always.
Real estate is more than a transaction - it’s a pivotal life transition. Since 1998, my approach has been driven by three simple pillars: Strategy, Service, and Success.
In a fast-moving market, you deserve more than a "one-size-fits-all" model. I provide a high-touch, concierge experience that combines local market intuition with sophisticated data analysis. Every move we make is designed to protect your equity, save your time, and give you a competitive edge.
Beyond the numbers and the listings, my true focus is our partnership. I am committed to being your advocate and trusted advisor long after the keys change hands.
Let’s cut through the noise and perfectly execute your next move.
Warmly,
Antoinette Sullivan

Sherry Phan
"I want to tell you that Antoinette is the Best agent we have had. She was not just an agent but also a friend. While looking for a home, she knew we were from Wisconsin, so she looked for the right home and right neighborhoods. She knew what we wanted. She was available to us no matter what time of day or day of the week. When I started moving into the new house my husband was out of town and the U-Haul battery died, Antoinette is the only person I knew, so I called her at 12:00 a.m. and she came out to help me. She is truly an amazing person!!"
Tina and John Steenson
"Antoinette kept us well informed about the progress of our escrow. She returned phone calls promptly. We were completely satisfied with her professionalism and knowledge. We would recommend her and would work again with her in the future. Everything was fast and efficient. We love our Agent, Antoinette Sullivan."
Mikaela Bonilla
"Ms. Sullivan was absolutely wonderful. Made my home purchase so much easier. She was always available, extremely patient, and her personality and attitude always remained the same. I would recommend her to anyone who is looking for an agent. I might add that this whole buying process was very enjoyable primarily due to Ms. Sullivan."
Juanita R. McCormick
"I searched for a realtor to handle the selling of my home and after looking at reviews, I chose Miss Antoinette Sullivan. We met discussed my needs discussed who she was and the rest is history. I have met my new best friend. She’s knowledgeable, professional just there for my every need from helping me pack up my house to climbing under the sink to make sure the plumber did his job. I could not have asked for a better experience. I wish I had another house to sell so I could work with Antoinette again."
Dolly Woodson
We had an outstanding experience working with Antoinette Sullivan. She sold our house in a very short time and for above what we expected, which was such a wonderful result.
From start to finish, Antoinette and her amazing team were professional, knowledgeable, and incredibly supportive. Because we were selling from a distance, we really appreciated how she took on all of the responsibilities and managed every detail seamlessly. She kept us informed, made the process stress-free, and truly went above and beyond.
We couldn’t have asked for a better real estate agent and would highly recommend Antoinette to anyone looking to buy or sell a home.
