Helping people to find their home and sharing in their excitement.

Mark services buyers and sellers in the majority of the residential communities in Pike and Wayne counties of Northeastern Pennsylvania. Some of these communities are in the Lake Ariel and Hawley regions of the Pocono Mountains.

Mark always had a passion for real estate, and when an opportunity arrived later in his business career he became a Realtor in the Pocono Mountains after leaving behind the hustle and bustle of New York life. Mark has a Master’s degree in Ocean Transportation and Logistics. He previously worked in the maritime industry as traffic manager, shipbroker, operations and marketing manager both on Wall Street and on Long Island.

Fun Fact about Mark: He is fluent in Polish and conversant in Russian! Besides being a husband to a fantastic wife, Magdalena, he is also a loving father to his grown up children. Mark also enjoys playing tennis, swimming, skiing, traveling to the medieval world, and getting excited while playing bridge.

Mark wants to help people find their permanent or vacation home, share in their excitement, and make them happy all while offering and utilizing his deep knowledge of geography, history, and the amazing attractions of this beautiful Lake Wallenpaupack area.  


“His knowledge, patience, warmth and willingness to help were extraordinary.
Mark wasn’t our first realtor, but he is definitely the last. We wouldn’t enjoy our beautiful lake house if it wasn’t for him.” – Yelena Gershenzon
