Who Is Andrew Jonathan Hillman? A Dallas Compliance Expert Witness on the Work, the Writing and the Giving
The short version, in my own words, with links to every record.
My name is Andrew Jonathan Hillman. Most people know me as Andrew Hillman, and some call me Andy. I live and work in Dallas, Texas. Andrew J. Hillman, Andy Hillman and A.J. Hillman all name the same person, and every one of those names points back to one official profile.
I am writing this so there is one plain answer to a simple question: what do I actually do?
The work
I am a senior paralegal and a healthcare compliance expert witness. Counsel retains me in writing in federal matters nationwide.
Let me start with what I am not. I am not an attorney. I do not give legal advice, and I do not tell a jury whether a claim was false. Legal conclusions stay with counsel. That line is the engagement.
So why does counsel call? Because a healthcare case is rarely only about the law. It is about how a business actually ran. Lawyers know the statute cold. They often need someone who has run the building.
Since 2020 I have been retained through counsel as an expert witness on healthcare operations, hospital business practice, and federal regulatory matters. My opinions draw on three decades of building and operating FDA-regulated healthcare companies. That record is the basis of my opinions. It is also their limit.
When I review a file, I look at it the way an operator would. I check whether the policies were practiced or just printed, whether the audits ran on a schedule, and whether people actually used the reporting channels. In my work as a retained compliance expert, the most dangerous document I see is rarely a bad claim. It is a good audit that nobody finished.
The writing
I write The Hillman Letter, a weekly letter on Substack. It covers healthcare compliance, expert witness practice and FDA regulatory strategy. Recent issues cover records retention, the 60-day overpayment rule and expert reports under Federal Rule of Evidence 702.
One line from the Rule 702 issue sums up how I approach reports: admissibility is now a writing discipline. Write for the gatekeeper first. The jury second.
Another, from the records issue, sums up what I see in clinics: most clinics I review have a retention policy. Few have a retention practice.
My papers and essays carry permanent Zenodo DOIs linked to my ORCID, 0009-0001-5396-321X. You can read the full list, with a page for each paper, on my publications page.

The podcast
The Hillman Letter Podcast has five short episodes in plain English. They cover healthcare compliance law, The Hillman Letter, my published work and my giving record. The show is educational only and is not legal advice. The episodes use an AI narration voice, and the show notes say so.
The giving
I fund two $1,000 essay awards for U.S. undergraduates. The Andrew Hillman Scholarship for Entrepreneurs has been open nationwide since March 2025. The Andrew Hillman Grant for Biotech supports students building a career in biotechnology, and its 2027 cycle is open.
In Dallas, I am a donor to The Lamplighter School, where a 2018 gift funded a technology and robotics space for students. I also support KidSwing at Scottish Rite for Children.
Hillman Ventures
I am the principal of Hillman Ventures, a private family office I founded in Dallas in 1995. Its holdings stay private by design.
