About me

My wife Susan and I live in Placentia with our four kids - Josh, Jacob, Dylan and Marlee.  We attend Friends Community Church.  When I'm not busy working, playing with family or helping coach my kids' baseball, I am usually in the garage covered in sawdust while pursuing my woodworking hobby.

  • Diedre Wachbrit Braverman

    I endorse this lawyer's work. David Hiersekorn is one of the most legally knowledgeable attorneys I know. He can cite code sections from memory and knows his law cold. That makes him a technically superb planner. Your plan will be done right and no one will break it. But David offers much more than an encyclopedic knowledge of the relevant law, he is dedicated to the right result for his clients and their families. He takes the time needed to make sure the plan fits each family's unique goals, using all of the tools he has at his disposal.
