With over six decades of combined experience, Koch St. Martin LLC has a proven track record of successfully resolving complex estate planning, succession, and tax matters. Our firm is led by partners David G. Koch, a board-certified expert in taxation and estate planning, and Michelle Lorio St. Martin, an accomplished estate planning attorney and litigator with extensive experience in succession contests, capacity disputes, and fiduciary litigation.

Both Michelle and David have been appointed by Louisiana courts to serve as administrators in contested successions, a reflection of their integrity, professionalism, and ability to navigate sensitive and high-stakes matters with impartiality and care.

As parents who have raised their own families in the Baton Rouge community, David and Michelle understand that estate planning is about far more than legal documents. It is about protecting the people you love, preserving what you have worked for, and giving your family clarity during life's most difficult moments. They bring that personal understanding to every client - taking the time to listen, learn what matters most for your family, and help you move forward with confidence and peace of mind.
