About me

Walt’s practice has focused for the past fourteen years on estate planning, trust administration, probate, conservatorships, and guardianships, as well as mediation of litigation involving those matters. He has been a board member of the South Bay Bar Association for the past eight years, and served as Co-Chair of the Trust and Estate Section and as Board Secretary during that time. He is an active member of the Probate Volunteer Panel for the Los Angeles Superior Court where he is appointed to represent proposed conservatees. Additionally, he does pro bono work for Guardianship Volunteer Panels and regularly participates in pro bono law days.


As a private mediator, Walt’s background and skills make him an effective facilitator and sounding board in helping to resolve a variety of trust, probate, and business disputes. He regularly serves as a volunteer settlement officer on the LASC Trust and Probate Mediation Panel, and previously spent more than five years as an active mediator on the Los Angeles Superior Court Alternate Dispute Resolution Panel. He has also participated as a member of the Southern California Mediation Association.


During a 25-year career in industry, Walt worked as a corporate lawyer, negotiated and managed major contracts and subcontracts, and held several senior management positions in the aerospace and telecommunications industries. His management roles include serving as Vice President of Operations for Hughes Global Services and President/CEO of the non-profit Galaxy Institute for Education before returning to practice law.

    Walt and I worked on a Conservatorship matter together. He has superb knowledge of the area and I would not hesitate to recommend him in matters involving Trust, Estate and Conservatorships. He is also a great mediator.

    I recently worked with Walt on a complex conservatorship matter. Walt associated me in as trial counsel. Walt's knowledge on conservatorships and his excellent skills in dealing with problem issues made him an outstanding team member. I strongly recommend Walt for conservatorship and trust matters.
