    I endorse Tassma wholeheartedly. She is a brilliant attorney and a top notch person. She always has her clients best interests in mind and she is one of the best asset protection minds I have had the good fortune to meet!

  • Ronald Lee Burdge

    I heartily endorse and recommend attorney Powers. With over 15 years of solid experience behind her, her honors graduation from Cannon Trust School, certification as a trust-financial adviser, and membership in Wealth Counsel, along with her published answers and two very nicely done Legal Guides published, one thing should be crystal clear - she knows the law and how to make sure that your assets are taken care of for maximum benefit to you and your heirs. When I started out in law I learned very quickly that the complexity and difficulties in Estate Planning took a special knack to learn and master. She has it. That's why I say that if you have an Estate Planning or Estate Law question, she is your answer. Period.
