Meet The Team

When we decided to form a business partnership back in 2006, we knew it would be something special. Not many brokers of our experience or influence form partnerships. Most go it alone, with junior agents that work to support them.

But our team is different – which means that as the team has grown, we have continued to break the mold.

Our team stands for honesty, integrity, and unwavering morals. That may sound like ‘just talk’, but it’s true, and our clients will speak to it (see what they have to say on Google here, or on our Testimonials page here). We will work endlessly to get you what you need and make the experience as smooth and enjoyable as possible.

We believe in being grateful for what we have, consistently showing up, and that New York is the best place to live in the world.

The Gasdaska Conlon Team specializes in residential Manhattan real estate, including luxury apartment rentals. Our team works with about 50% sellers and 50% buyers, so no matter your real estate needs, we can help.

Why We’re the Right Team For You

If you are looking to sell or rent a property you own, we’re the team for you. We will guide you every step of the way. We’ll tour your apartment, work with you to find a realistic and competitive price, and then market it until we’ve found the right buyer for you.

Are you looking to purchase a property in Manhattan? Let us help, and make the process fun again. We know how stressful finding properties that fit your individual needs can be. We’d love to take that load off your shoulders. We’ll work with you to quickly find exactly what you are looking for, help you put together an attractive offer, and guide you through the purchasing process all the way through closing.

Above all else, we are grateful for the careers we have been able to build, and those we share it with. Every member of our team is incredible at what they do, and we love working with each other. If you would like to get to know us more as individuals, see below.

If you are ready to get started, feel free to reach out. We’d love to speak with you, even if you are just dreaming.
