They meet regularly to discuss a wide range of topics as well as presenting any special cases they have encountered within their own practices.

Dr. Liebes also stays very busy outside of the office! His daughters have graduated from Drexel and Rutgers University and the whole family enjoys cheering on the Rutger’s football team at all of their home games! Dr. Liebes has accomplished many great personal triumphs including 3 half marathons.
