The Estate Planning Lawyers and Staff at Galligan & Manning

Our History

In 1997, Mary Galligan and Tammy Manning formed their partnership and chose as their office a charming Victorian home built in 1914 and located near downtown Houston.

Both Mary and Tammy received their legal training at major Houston law firms. After leaving their respective firms, they collaborated on several cases and found that their philosophies and styles complemented each other.

The firm has attracted talented attorneys and staff who have joined Mary and Tammy in focusing exclusively on a trust and estate practice, including estate planning, probate, elder law, and disability planning.  Because of her extensive experience with probate litigation and her interest in resolving problems before they reach the courthouse, Tammy now focuses her practice on mediating probate and guardianship disputes.

    Kevin Horner handled my sister's probate quickly and efficiently. He was also able to help me with my own estate planning solving a problem created by the unexpected loss of my sister. I worked with several others at the firm who were assisting Kevin and it was alway a pleasant, efficient experience.
