She conducted herself to a high level, was very professionally and always prompt with answers to any questions I ever had.

Sheryl made it a very smooth process and I would highly recommend her to family & friends.

Mark Anderson recommends Vincent O'Brien

Educator with the NYCDOE

When my wife and I first began looking around for a new place to live, we had absolutely zero experience and knowledge of what it takes to buy a home, as we had only lived in apartments prior. We weren't even sure we were ready for it, and most of the realtors we'd spoken with didn't bother asking us any questions or explaining much of anything. The first time I spoke with Vince, he patiently listened as I explained where we were in the process, and just as patiently took his time to explain the ins and outs of looking for a new home. So it was a no brainer once we were finally ready to put in an offer that we would ask Vince to represent us. He worked closely with us all of the way, always taking the time to explain whatever we needed to know, and we are now proud new owners. I highly recommend Vince.
