Law Office of Lawrence F. Dietlein, Jr.: The Houston Estate Attorney Who Started in Molecular Biology, Not Law

Lawrence F. Dietlein, Jr. earned his undergraduate degree in Molecular Biology and Chemistry from the University of Texas at Austin before ever setting foot in law school — then added a master’s degree in Philosophy from the University of Houston on top of it, a scientific-and-philosophical academic path that is unusual preparation for a career now built entirely around estate planning and probate.

Origin and Background

The Law Office of Lawrence F. Dietlein, Jr. is located at 1 Greenway Plaza, Suite 100, Houston, TX 77046, confirmed through Martindale-Hubbell attorney records. Dietlein has been licensed in Texas since 1998 and holds a J.D. from Texas Wesleyan University School of Law (now Texas A&M University School of Law) along with an LL.M. in Tax Law from the University of Houston Law Center. He holds board certification in Estate Planning and Probate Law from the Texas Board of Legal Specialization, independently confirmed through Martindale-Hubbell, Lawyers.com, and Lexinter’s TBLS-sourced directory.

Practice Concentration

The boutique firm focuses on estate planning, probate administration, and fiduciary representation — drafting wills, powers of attorney, and trusts, and advising both individual and corporate fiduciaries on comprehensive trust and estate administration. For matters outside this core focus, the firm works with a network of outside attorneys covering civil and criminal litigation, personal injury, wrongful death, and tax litigation rather than handling those areas in-house. See this Houston Estate Planning & Probate directory for how this single-attorney boutique compares to larger multi-attorney firms also serving Harris County.

Notable Work / Track Record

As is typical for an estate planning and probate 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 Dietlein’s LL.M. in Tax Law layered on top of his TBLS board certification, and his membership in Attorneys in Tax and Probate and the Disability and Elder Law Attorney Association, both specialty-focused professional groups.

Client Voice

Avvo-hosted client reviews describe Dietlein as “very professional,” with one reviewer — heading into retirement and needing estate planning and will preparation completed before a trip — specifically praising him for delivering on a hard deadline after having “interviewed” several other attorneys who didn’t fit their needs. A second reviewer, an attorney practicing in the same field, offered a professional endorsement of his work. Awesome Attorneys did not identify a pattern of negative or critical reviews warranting disclosure.

Beyond the Courtroom

Dietlein is a member of the Texas Bar College, the Houston Bar Association, and the Fort Bend County Bar Association. Awesome Attorneys did not identify separate non-legal civic or nonprofit board service documented for him beyond his professional bar memberships.

Recognition for This Houston Estate Planning Attorney

Dietlein’s Board Certification in Estate Planning and Probate Law from TBLS is independently confirmed across Martindale-Hubbell, Lawyers.com, and Lexinter’s specialization-focused directory. He has also received Avvo’s Client’s Choice and Top Contributor badges. Awesome Attorneys distinguishes the state-administered board certification from these self-submitted directory badges, which reflect platform activity and review volume rather than peer or examination-based evaluation.

Texas Legal Backdrop

Texas has no state estate or inheritance tax, though the federal estate tax may still apply to larger estates depending on the exemption amount in the year of death — a consideration informed by Dietlein’s LL.M. in Tax Law. Under Texas Estates Code § 256.003, a will generally must be offered for probate within four years of the decedent’s death, with limited exceptions for a party not in default. Texas Estates Code Chapter 401 governs independent administration, allowing a named executor to act with minimal ongoing court supervision once appointed. None of this is legal advice; a specific estate or probate matter should be evaluated by a licensed Texas attorney based on the actual facts involved.

Awesome Attorneys Assessment

Lawrence Dietlein’s clearest differentiator is a genuinely unusual academic path — molecular biology and philosophy before law — paired with an LL.M. in Tax Law stacked on top of TBLS board certification, backed by specific, attributed client reviews about hitting hard deadlines under pressure. The honest trade-off is that, as a single-attorney boutique that refers out litigation and other adjacent matters, clients with complex disputes alongside their estate planning needs will need a second attorney for that work. For a Houston-area client whose estate planning has meaningful tax complexity and wants a board-certified specialist personally handling the matter rather than passing it to associates, that combination is a reasonable basis for a shortlist.
