Lieberman and Associates was founded in 1998 by Alan Lieberman. After starting at Leo Burnett and working in senior positions for Darcy, Jack Levy and Associates and Keroff and Rosenberg, Alan chose to take his 25 years of experience and form a more personal partnership with his clients. He created a full service advertising and communications agency built on an overriding philosophy: We don’t work for our clients. We work with our clients – as their marketing and communications partner.
