About me


Buy. Sell. Invest.

As an agent, I have not only enjoyed working with buyers and sellers in the Hudson Valley but also investors who would like to earn income while owning real estate in New York. The Hudson Valley is a beautiful place and the real estate side of it is a journey in itself. So please, contact me with whatever your real estate needs are because I look forward to hearing from you.

Amazing, awesome, reliable, absolute professional! Mark helped us sell our house in Fishkill, NY, a large Cape. After speaking to him and hearing what he had to say, and all the suggestions he had, to help us sell our property, my husband and I had complete and total faith in him. We knew the sale of our home was in good hands! He is very honest, and followed up on every phone call quickly. I was very impressed that he knew the area very well. Mark is easy to work with, honest, gets the work done, and is dedicated to his clients. I highly recommend him. Mark is the best!
