About me

I received the California State Bar specialist designation in Estate Planning, Trust, and Probate law in 2010.  My practice focuses on estate planning for high net worth individuals by implementing a team approach to planning with the client's CPA, financial advisor, and insurance advisor.  


In addition to my legal work, I provide pro bono help to Churches and religious ministries (also on the formation of those organizations).  I am also active in my church, Faith Bible Church of Ladera Ranch.
