Mary Elizabeth Coleman


Mary Elizabeth Coleman is Chief Executive Officer of TuckerAllen. As an estate planning attorney with experience funding and developing start-ups, Mary Elizabeth is uniquely qualified to lead TuckerAllen.

Mary Elizabeth started her estate planning practice at the law firm Oppenheimer, Blend, Harrison and Tate in San Antonio, Texas. She and her husband then moved their family to St. Louis to be near family, where she started her own taxable estate planning practice. Mary Elizabeth quickly established herself as a competent and well-respected attorney in town, helping individuals and families carry out their very personal wishes.

When Mary Elizabeth returned to St. Louis, she joined the The Billiken Angels Network (BAN). BAN provides investments of capital and expertise to help launch or grow businesses at all stages and in all industries in the St. Louis region. As Lead Fellow, Mary Elizabeth consulted and mentored companies from application to funding, and she assisted BAN investors and fellows with business plan evaluations and investment due diligence. She currently serves as a board member of Arch Grants.

Mary Elizabeth brings this depth of legal and business experience to her position as leader of TuckerAllen. It is her vision of transparency and an exceptional client experience that differentiates TuckerAllen as a firm offering personalized, face-to-face, and “high-touch” estate planning services with no hidden costs.

Mary Elizabeth remains committed to supporting entrepreneurs and small business owners in her community, and resides with her husband and five children in Jefferson County.
