"We recently had the pleasure to work with Antonia to both buy and sell our home. We highly recommend Antonia for her many attributes, but above all her grace, knowledge, and determination. She is a professional real estate agent who will ensure all your questions are answered and concerns are addressed. Antonia demonstrated she was dedicated, understanding, and highly responsive to our needs. Her design skills for staging our home totally exceeded what we ever imagined; with a few changes, she was able to transform the space beautifully, as a designer would. Antonia did not rest until she assisted in finding the perfect match for our new home! She advocated and negotiated for us so that we could seamlessly purchase our new home; she made it happen! We are so grateful for all her knowledge, professionalism, and just being such a relatable, mindful, and kind person that she is. We are so happy with the outcome of our experience with Antonia, and would not hesitate to work with her again in the future."

About Antonia

I grew up in a close-knit Albanian American family, and moving frequently throughout my childhood taught me something invaluable: how to adapt, listen, and connect with all kinds of people. What once felt challenging became one of my greatest strengths — the ability to walk into new situations with confidence and empathy.


Before real estate, I built my career around working with people. I earned a degree in Education and History (grades 7–12) and spent five years teaching middle school U.S. History in the New York City while completing my Master’s degree. Teaching sharpened my communication skills, patience, and ability to guide others through complex processes — skills I now bring to every client relationship.


After starting my family and returning to Connecticut, I pursued the things that inspire me most: connecting with people, educating and advising others and cultivating my love of thoughtful design. I earned my yoga teaching certification and taught for several years, then opened a decorating business focused primarily on real estate design and staging, along with select projects. Helping homeowners present their properties at their absolute best naturally led me back to real estate.


I was first licensed in 2016, returned to the profession in 2020, and spent three years working as an assistant, gaining invaluable behind-the-scenes experience in contracts, negotiations, and transaction management. Now, with my youngest graduating and the ability to give this career my full focus, I’m fully committed to serving buyers and sellers with energy, organization, and attention to detail.


If I had to summarize my approach, it’s simple: I love working with people. My entire professional life — teaching, yoga, design, retail, and real estate — has centered around building relationships. I’m highly organized, detail-oriented, and thoughtful in my communication. I believe real estate isn’t just about houses; it’s about understanding people’s lives, transitions, and goals.


Whether you’re preparing your home for market, searching for the right space, or simply exploring your options, I bring care, creativity, and clarity to every step of the process.
