Founder Mark Liberman has been in the Condo/Co-op Property Management field for over 20 years. After moving to Connecticut, Mark obtained his Real Estate license in 2004, later acquiring a Brokerage in 2012. With the market fluctuations, Mark recognized that there was an opportunity to take his Real Estate and previous business experience to expand his services to Property Management, thus incorporating On the Mark Management, Property Management/Real Estate, LLC.

Since incorporating On the Mark Management in 2010, the practice has increased from a single licensed Real Estate Broker to a staff with combined Real Estate and Property Management experience of 30+ years. Our current staff includes 6 Licensed Relators and 8 Community Associations Managers, who collectively manage 18 properties (approximately 1500 units), consisting of multi-family rentals, condominiums, co-ops and mix-use residential/commercial properties.
