About Mark D'Angio

Mark D’Angio is a true people-person! Prior to real estate, Mark worked 34 years as a radio morning show host on WALK-FM 97.5 Long Island, NY. Though he was able to participate in a lot of fun activities for that job, he finds real estate offers excitement in its own way. When working directly with buyers and sellers, Mark enjoys one-on-one contact with his clients and loves helping them achieve their goals.

Mark works through the Stony Brook Howard Hanna-Coach Realtors’ office and is a licensed real estate salesperson. He credits Coach Realtors’ high-standing reputation on Long Island and the supportive, professional, knowledgeable, family feel we provide. Having lived in Suffolk County for 37 years, Mark is no stranger to most towns there. He grew up in Nassau County and holds in-depth knowledge of Merrick, Rockville Centre, and Baldwin.

Armed with a BA in Psychology from SUNY Cortland and a goal of helping as many clients as he can, Mark finds his joy in helping people find or sell a home. He considers a recent near-million-dollar home sale a highlight and looks forward to many more! When Mark isn’t busy helping people purchase or sell properties, he volunteers as a videographer/photographer for the Three Village School District, as well as taking photos and video as a hobby. He also loves building and working on computers, as well as cooking. Give Mark a call today! He’ll be happy to sign you up for a complimentary Market Watch report, or just chat about your needs.
