About me

I opened the KMA Law Office in 2010 as a general practice firm that focuses on: automobile and work injury claims, wills, trusts, estate planning and administration, and collections. KMA Law Office is a full service law firm which also assists individuals and business in the areas of foreclosures and debt collections.

I stay on top of the current issues and changes in the law with continuing legal education seminars on a regular basis. I started working in the legal legal profession over 20 years, as a paralegal in 1990, working with attorneys in the areas of criminal law, family law, personal injury and medical malpractice.

  • Jobeth Rocky Bowers

    Karen spent nearly a decade in the profession before becoming a lawyer. As someone who did the same, I understand how valuable that is to a lawyer. She knows how to do everything in every case she handles, and you can be confident that she will not just delegate or "dump off" the tedious tasks to low level employees that may overlook the finer and more important details in your matter. A great client advocate who keeps herself on point with all relevant updates in the law, as a member of several important organizations.

    I worked with Ms. Authement for several years on real property tax matters. During that time, her professionalism, subject matter knowledge, writing and advocacy skills were always on display. I endorse her unhesitatingly to any seeking a skilled, intelligent advocate to represent their interests.
