About me

I founded The Allison Firm, PLLC to use my more than thirty years of legal and tax experience providing high quality estate services to clients. The firm focuses entirely on estate matters. Aside from estate planning and probate & administration, the firm is skilled in estate dispute litigation.  We also do estate taxes including tax returns for estates and fiduciaries, gift taxes, generation skipping and other tax planning, estate tax return audit defense, and estate tax litigation.


I earned my B.A. in English from the University of Georgia, then pursued a J.D.(law) degree from the University of Tennessee, and my LL.M in Taxation is from Emory University.  


My first career position was in private practice before joining the Department of Health Education & Welfare as Assistant General Counsel for Litigation. Next, I worked as an Estate and Gift Tax Attorney for the IRS prior to re-entering private practice with Witt Gaither & Whitaker. When I moved to Oklahoma, I started The Allison Firm, PLLC. 


My law licenses are in Oklahoma, Tennesse, and Georgia. I am admitted to practice in all levels of those states' courts and before the U.S. Tax Court, the 4th, 5th, 6th, and 10th Circuit Courts of Appeal, the U.S. Tax Court, and the U.S. Supreme Court.  I'm currently a member of the Tulsa County Bar Association, the Oklahoma Bar Association, the State Bar of Georgia, the Tennessee Bar Association, and the American Bar Association.  My professional memberships also include the Estate Planning Forum of Tulsa, Tulsa Title and Probate Lawyers Association, and Wealth Counsel. Recently, I was past chair of the Oklahoma Bar Association's Estate Planning Probate and Trust Section.


I'm often on the road as a speaker, lecturing on continuing education for professionals and holding interactive workshops for lay groups. As an adjunct professor, I taught estate law at Northeastern State University and jurisprudence at the University of Tennessee. 


At home, I serve on the St. John Health System Institutional Review Board, the Advisory Board of Select Life Management and many charitable organizations. I am proud to be the mom of two military sons.

    I endorse this lawyer. Gale Allison dedicates her practice to trusts, wills, estate planning, prenuptial agreements, and litigation involving those same subjects. The more complex the issue, the more I would urge clients to retain her as their counsel.

    Ms. Allison advised me in various Trust matters involving a family Trust for which I was a Trustee. Her advice was invaluable in avoiding litigation and resolving a difficult issue. In addition she advised me with regard to estate planning for my elderly mother.
