Our History


Markotsis & Lieberman is a general practice law firm formed in July, 1990, consisting of it’s two partners, James C. Markotsis and Douglas M. Lieberman, an associate, George Neofitos, and an experienced support staff.

When they first opened, they had virtually no clients. But what they lacked in clients they made up for in ambition and drive.

As their client base grew, so did the size of their staff. George Neofitos, the current Associate, joined the firm in 2002. The staff also currently includes three paralegals and a secretary, all of whom are experienced. The firm moved into its present location in 2011.

During their nearly 30 years of practice, the firm attorneys has become trusted counsel to numerous individuals as well as to businesses of all sizes, including many of whom you are familiar with. And during that time the attorneys have never lost sight of what it takes to be successful – to listen to the client’s wants and needs, and to use their experience, integrity and knowledge to try and obtain the best possible result in line with those wants and needs. It is what continues to drives them.

Throughout their years in practice, the attorneys have been involved in community groups and activities, including leadership positions. Professionally, they have had articles published in legal publications and have had cases reported, with their cases being cited in other cases. They have also been actively involved in the Nassau County Bar Association, with Jim being a member of the Grievance Committee and Doug being on the Board of Directors from 2009-2012 and now being a member of the Nominating Committee.
