Explore Riverdale

Welcome to Riverdale, a proud Bronx neighborhood of leafy trees, palatial, historic mansions, rolling hills, and scenic views, just minutes from Manhattan and seemingly far away from its thunderous hustle and bustle.

What was once mostly rural farmland and a summer retreat for wealthy Manhattanittes is now a charming enclave with two cherished historic districts, a selection of the top schools in the city, a lively culinary scene, and an increasingly diverse pool of residents.



Geoff and Aaron helped us make our first home purchase in NYC.

We had worked with several realtors throughout the process and we knew immediately when we met them that they were different. They are honest, straightforward, and were communicative every step of the way. Their assistance with preparing our mammoth board package was invaluable and we found a home that was exactly what we needed and wanted. We’d highly recommend them!

The virtual staging and photos were stunning!

I LOVED working with Geoffrey! He made the process seamless – he managed the clean-up, painting and other prep. I also had multiple offers after being on the market for a couple of days. He is amazing!

It was a great pleasure to work with Geoffrey!

I never got a chance to meet him in person but with his professionalism and constant communication, I felt that I did. He made the process in which I was losing hope on feel so comfortable and seamless. I never once doubted the trust I had in him and every time he was needed he delivered above and beyond! – Rolando R., Landlord in Kingsbridge, Bronx – 2020

Aaron and Geoff were fantastic to work with!

We were interested in purchasing in Riverdale but didn’t know much about the neighborhood. They took the time to not only show us homes in the area but provided a tour as well as tips on the best restaurants. When we made an offer they helped walks us through the entire process and provided great recommendations for our lawyer as well. I would highly recommend that you reach out to them if you are looking to purchase a new home.

Here’s the TL;DR: Geoff and Aaron are incredibly attentive, caring, personal agents who also happened to get us 50k more than we thought was possible. I’m not sure I could ask for anything more.

Here’s the story: We met with Geoff and Aaron as we were getting ready to sell our first house and Geoff asked what our experience buying and selling real estate had been like. I said plainly that buying the house we were now selling was probably the worst experience of my life (we did it without an agent—got pressured, pushed around, and bullied). He promised this would be an improvement. They made a convincing presentation and are fun in a way that you want to be friends with them after the sale, but here’s the important thing they did in that meeting: They gave us realistic expectations even as they were trying to get our business. Their estimate of how long it would take to sell our house, which was a pretty odd and singular property in the area, was within a week of what happened. They also made our particular situation as easy as it could be. We had moved out, but they were at the house watering plants, picking up mail, and meeting repair people as necessary. We had someone push a BS offer for WEEKS as soon as it went to market and they dealt with that situation, knowing the specifics of our house and what kind of buyer we ultimately needed to find. Ultimately they found that buyer and the price was much higher than what we had even discussed as a top end in our initial meeting. The last thing that makes them so right for where they work is that they are so damn interested in all the history that’s in the area. The Bronx is an odd man out in New York real estate but there are so many beautiful properties and special parts of it. Geoff and Aaron can go chapter and verse on most of it. If you live in the BX and are looking to sell or you’re trying to figure where the hell in NYC you can buy real estate (it’s probably the Bronx), they will help set you up for success.
