  • Steven Robert Kampf

    I have known Jeff since he started his own solo law practice in 2007 and have had the pleasure to see him grow into an extraordinary family law attorney. Jeff zealously advocates for his clients and has great relationships throughout the San Diego legal community. I would highly recommend Jeff to anyone looking for a family law attorney.

  • Michael Jeffers Hoisington

    I've known Jeff since he came to San Diego in 2007. He proceeded to pass the California bar and start up his own practice - not exactly tasks for the faint of heart. As expected, he's done very well. He has the skill, knowledge and temperament to handle stressful family law matters. Highly recommended!
