Gyeszly + Prangner: The Houston Estate Boutique Founded by a Former Private Family Office Director

Before founding her own firm, Amanda Gyeszly served as Director of a private family office in Houston — a role that put her on the client side of the exact wealth-transition decisions she now advises on as outside counsel, a perspective few estate planning attorneys bring to the table.

Origin and Background

Gyeszly + Prangner, PLLC is located at 3701 Kirby Drive, Suite 500, Houston, TX 77098, confirmed through the firm’s own site and State Bar of Texas records. Amanda M. Gyeszly earned her J.D. with Honors from The University of Texas School of Law in 2004 after a B.S. from the University of Texas at Austin in 2001. She holds board certification in Estate Planning and Probate Law from the Texas Board of Legal Specialization, independently confirmed through Lawyer Legion’s TBLS-sourced Harris County directory. Before founding her current firm, she practiced as a shareholder at Fizer Beck and served as Director of a private family office in Houston.

Practice Concentration

The boutique firm focuses on complex estate planning and gifting strategies, business succession planning, charitable giving and exempt organizations, trust and estate administration, and marital property issues, along with related fiduciary, income, estate, gift, and generation-skipping transfer tax matters. Gyeszly has moderated sessions at the State Bar of Texas’s Advanced Estate Planning Strategies Course, a signal of standing within the state’s specialist bar. See this Houston Estate Planning & Probate directory for how this boutique compares to other Harris County firms in this category, including the larger firm Gyeszly previously practiced at.

Notable Work / Track Record

As is typical for an estate planning and administration boutique, the firm does not publish a table of case verdicts or settlements, and Awesome Attorneys did not identify one — this practice area centers on drafted plans and completed administrations rather than litigated outcomes. What is independently verifiable is Gyeszly’s TBLS board certification, her prior shareholder-level tenure at an established Houston estate boutique, and her invited moderator role at a State Bar of Texas advanced-practice conference.

Client Voice

Awesome Attorneys did not identify published, attributed client reviews for Gyeszly + Prangner on Avvo, Yelp, or Google as of this writing — consistent with a newer boutique built substantially on referral relationships from Gyeszly’s prior family-office and Fizer Beck tenure, though Awesome Attorneys discloses this review gap rather than papering over it.

Beyond the Courtroom

Gyeszly’s clearest form of public-facing service is professional education: moderating “Practicing on the Cliffs of Insanity Without Falling into the Pit of Despair” at the State Bar of Texas’s 31st Annual Advanced Estate Planning Strategies Course. Awesome Attorneys did not identify separate non-legal civic or nonprofit board service documented for her.

Recognition for This Houston Estate Planning Boutique

Both Gyeszly and her partner Arielle Prangner are listed on Super Lawyers for Estate Planning & Probate. Gyeszly’s Board Certification in Estate Planning and Probate Law from TBLS is independently confirmed through Lawyer Legion’s specialization directory. Awesome Attorneys distinguishes this examination-based, peer-administered credential from self-submitted marketing-directory placements.

Texas Legal Backdrop

Marital property issues — one of the firm’s stated focus areas — intersect with estate planning in Texas because Texas is a community property state, meaning most property acquired during a marriage is presumptively owned equally by both spouses regardless of whose name is on the title, which affects how much of an estate a surviving spouse can dispose of by will versus what already belongs to them outright. Texas has no state estate or inheritance tax, though the federal estate tax may still apply to larger estates depending on the exemption in effect in the year of death. Texas Estates Code Chapter 401 governs independent administration, letting an executor act with minimal ongoing court supervision once appointed. None of this is legal advice; a specific estate or marital property matter should be evaluated by a licensed Texas attorney based on the actual facts involved.

Awesome Attorneys Assessment

Amanda Gyeszly’s clearest differentiator is a client-side perspective few competitors can match — running a private family office before returning to practice as outside counsel — paired with TBLS board certification and a specific specialty in marital-property-adjacent estate planning relevant to Texas’s community property system. The honest trade-off is that, as a newer boutique built substantially on referral relationships, Awesome Attorneys could not identify independently published client reviews to weigh against her professional credentials. For a Houston-area client with complex, multi-generational wealth-transition needs who values an attorney who has personally run the client side of that process, that combination is a reasonable basis for a shortlist.
