About Me

I am an entertainment lawyer.  Was awarded entertainment lawyer of  the year by the California Lawyer's Magazine.  I am a black belt in Karate and founded and built on of California's largest firms, with 150 lawyers and 5 offices in two states.  I stepped down two years ago, freeing me from administration duties and more opportunity to practice law.


I also write and have published works on Entertainment law and been on the front page of the New York Times, LA Times, Boston Globe, Daily Journal, CNBC and numerous other media outlets.

    I endorse this lawyer. He has been my supervisor and mentor over the past year and a half and working with him, in addition to being a delight, has also even more importantly accelerated my experience level and quality as a lawyer more than i thought possible. Despite carrying his own heavy case load, no matter how bogged down he is, he always finds the time to patiently lead me and supervise my work in a manner that has solidified my self esteem but in addition has instilled our client's confidence in my ability to consistently deliver a high quality and thorough work product, I cannot say enough good things about this person as a lawyer or as a human being.
