About Me

Our firm's primary focus is family security using our combined 35+ years of experience and the tools of estate planning and defensive estate planning (asset protection) to accomplish our client's goals.  I have represented as many as 3 generations in many of my clients' families doing legacy planning.  Early in my law career  I was involved in oil and gas law but when I had my children I switched to family law.  Since I began focusing on estate planning 25+ years ago - I have been able to use my previous legal experiences to bring an understanding of family dynamics, familial wealth, especially Texas'  large landowners and the importance of families of all kinds, to all of my clients estate planning.  I am  BOARD CERTIFIED in estate planning and probate law with over 25 years of experience.  I come from a large family with many diverse relationships that bring a very personal understanding of complex familly issues.  Being a landowner - raising horses, longhorns and my understanding of oil and gas law makes me appreciate all that is Texan. 

Giving back is important and I serve in many legal organizations as well as on boards in Austin that give back to the community including the Dell Children's Womens Trust, LTLov  and as an advisor to many more including Dream a Dream Therapeutic Horsemanship, Africa's Promise Village and others. 

I have a large extended family including 3 children, a son in law, horses, longhorns, chickens, a rescued squirrel, 3 cats and 4 dogs.
