My 16-year-old daughter, Helena, recently expressed an interest in helping veterans for a high school service project. I immediately took out my phone and emailed my partner Colleen Hart, a veteran of the U.S. Navy, who is heavily involved in veteran volunteer efforts.  Colleen wrote me back inviting Helena to help with the Los Angeles County Bar Association’s Veterans Legal Services Project (VLSP), a clinic that assists Veterans with legal issues.

Helena worked with Colleen at the VLSP in March, and returned home telling me how much she enjoyed the experience and the meaningful work.  The clinic meets once a month, so I decided to join her the next time she went. In preparation, I took a training along with several attorneys from Proskauer and our client A&E Television Network.
