  • Georgia Lee Williams

    I have sent several clients to Jonathan. He has done beautiful work and the clients have been very happy.

  • Nathan Kased

    As a rookie lawyer, I was in the unenviable position of opposing Jonathan--a highly distinguished lawyer and partner at a prominent San Diego law firm--on an employment discrimination matter. Despite his exceptional prowess and experience in employment litigation (and my being overmatched), Jonathan was the consummate professional. He was always ethical, courteous, and fair, all while zealously advancing his client's interests. I endorse him without reservation.
