Tim Huey, JD
D. Timothy (Tim) Huey has spent over 35 years developing a well-earned reputation as an authoritative source

matters and tries to pass on what he has learned through writing and teaching.
Mr. Huey is the lead author of Ohio OVI Defense – the Law and Practice, which is published by Lawyers &
Judges Publishing Co.
Tim loves to teach and has given over 100 DUI related CLE presentations to lawyers in Ohio, Oklahoma,
Georgia, Texas, Wyoming, Florida, Arkansas, South Carolina, Colorado, Michigan, Illinois, Arizona,
Maryland, Tennessee, New Hampshire, Indiana and Texas and has led Intensive Trial Skills Training sessions
for the Ohio Association of Criminal Defense Lawyers, the national DUI Defense Lawyers Association, the
National College for DUI Defense, and the Trial Skills University and other organizations.
Below are some of his recent accomplishments in the courtroom and in the profession.
• In 2022 Tim successfully passed the rigorous DUIDLA Board Certification Exam.
• In 2021 Tim was honored to have received the DUIDLA’s Badass Award.
• In 2019 Tim was lead counsel for the DUIDLA on an Amicus Brief filed in the Supreme Court of
the United States in Mitchell v. Wisconsin which involved warrantless blood draws in DUI cases.
• In 2018 Tim was elected as President of the national DUI Defense Lawyers Association and
currently serves as CLE Chair for the DUIDLA.
• In 2017 Tim once again cross-examined the head of ODH Alcohol and Drug Testing Program and
even after she had gone through extensive training at the DataMaster factory, once again convinced
a judge that she should not be qualified as an expert on the DataMaster – even though she is the
official who approves the breath testing machines for use in Ohio and writes the rules and protocols
governing these machines. State of Ohio v Zack Benner, Lima Ohio Municipal Court case number
16 TRC 05502, ruling January 30, 2017.
• In 2016 Tim cross-examined the head of the Ohio Department of Health’s Alcohol and Drug
Testing Program, who is also their chief toxicologist, and convinced the court to find that she: 1)
was not qualified to give expert testimony about the BAC DataMaster breath testing instrument and
2) has very little training in toxicology. State of Ohio vs Michael Venturelli, Lima Municipal Court
Case Numbers: 15 TRC 07221 transcript of trial April 19, 2016.
• In 2015 the speaker of the Ohio House of Representatives appointed Mr. Huey to the Ohio Criminal
Justice Recodification Committee where he may have an opportunity to help infuse a little common
sense and justice into the process as he and other committee members rewrite the Ohio Criminal
Code. He is one of only four criminal defense lawyers on the committee and the only committee
member whose practice is primarily focused on DUI defense.
• In 2014 Tim became a Charter Member of the DUI Defense Lawyers Association (DUIDLA) and a
Trustee for the DUI Defense Lawyers Association’s Justice Foundation.
• In 2014 in Cincinnati v Ilg, in the Ohio Supreme Court, Tim argued as Amicus Counsel and the
case resulted in a holding that (contrary to 30 years of case law and judicial wisdom in Ohio) the
accused can challenge and question breath results and breath instruments and thus the defense has
the right to obtain electronic (COBRA) data to bring such challenges and raise such questions.
• In 2013 Tim again worked with and led a team of lawyers in State of Ohio v Chelsea Lancaster
where the State presented testimony of CMI Engineer Brian Faulkner and other experts and the
defense presented testimony of Dr. Al Staubus, Dr. Mike Hlastala and Tom Workman. The results
was a ruling that the Intoxilyzer 8000 results “are not scientifically reliable” and was the first time an
Ohio court has held that the defense has proven that a breath testing device is unreliable. As a result
the majority of Ohio police departments ceased using the Intoxilyzer 8000.
• In 2012 Tim was elected President of the Ohio Assn. of Criminal Defense Lawyers (OACDL) and has
run their annual three (3) day Advanced DUI Defense Seminar which runs March 12-14, 2020 (feel
free to ask for details.)
• In 2011 Tim helped lead a team of lawyers in the first case in Ohio where the defense undertook a
head-on challenge to the Intoxilyzer 8000, the ODH procedures and the head engineer for CMI / the
manufacturer of the 8000; State of Ohio v. Nicole Gerome. The result was a ruling that the Intoxilyzer
8000 has vulnerabilities and limitations and the accused shall be permitted to introduce all relevant
evidence about the machine at trial.
Tim has authored many articles on DUI issues for publications such as The DWI Journal: Law & Science, the
National College for DUI Defense Journal, the OACDL Vindicator. He has authored or co-authored as
Amicus Curiae briefs in: State v Ilg where the issue is whether State v Vega prohibits an accused from
seeking to challenge the reliability his Intoxilyzer 8000 breath test results and in numerous other matters
including Ohio Supreme Court cases involving preliminary breath testing and field sobriety testing, including
HGN (State v Derov), blood testing (State v Mayl) and destruction of video tapes (State v Lupardus) all of which
made or preserved favorable case law for those accused of OVI in Ohio.

After graduation from law school, he spent nearly 6 years as a prosecutor before joining in 2023.

California attorney, Kristen Campbell, who used to work for Lawrence Taylor’s Law Firm in the Los Angeles

Mark Thiessen, JD
Mark Thiessen prides himself on being an aggressive trial lawyer. If the district attorney will not bargain or
justice will not be served by allowing the client to plead guilty, Mark passionately and professionally represents
his clients at trial. He has won DWI cases from total refusals up to quadruple intoxication manslaughter. Mark
has earned formidable reputation for being a tenacious Houston DWI trial lawyer, and he works hard to
maintain that status. Mark is licensed and tries cases in Texas and Colorado.
Since opening Thiessen Law Firm, Mark has continued to add to his growing list of accomplishments. In
addition to his widely publicized feats as a winning Houston intoxication manslaughter lawyer, Mark Thiessen
was the youngest criminal Super Lawyer in Texas in 2013. As of 2021, Mark is a 9 time Texas Super Lawyer, 5
time Top 100 Super Lawyers in Houston and 3 time Top 100 Super Lawyers in all of Texas. For the past two
years, Mark has been the only DWI lawyer listed in the Top 100 in Houston and the only criminal Super
Lawyer listed in the Top 100 Lawyers in Texas.
Mark is the only lawyer in America who is triple board certified in:
1. Criminal Law by the Texas Board of Legal Specialization
2. DUI Defense by the National College for DUI Defense as approved through the American Bar Association
3. DUI Law by the DUI Defense Lawyers Association.
Mark has also earned the American Chemical Society-Chemistry and the Law’s (ACS-CHAL) Forensic
Lawyer-Scientist designation — the highest form of scientific recognition available for lawyers.
Mark is also a frequent legal seminar lecturer, author of numerous published legal articles, and a faculty
member for various organizations. Mark is an international lecturer and is regularly called on to speak and
educate students, police officers, lawyers and judges.
Mark Thiessen was born and raised in Houston, Texas. Mark attended the Village School and St. Francis
Episcopal Middle School before graduating from the Kinkaid School in 1996. Mr. Thiessen then attended and
graduated from Texas Christian University in 2000 with a Bachelor’s of Business Administration in Marketing.
While at TCU, Mark was a member of Phi Delta Theta fraternity and on the dean’s list.
Following his time at TCU, Mr. Thiessen returned to Houston and began his law school education at South
Texas College of Law (STCL). Mark made the most of his time at STCL, actively taking part in mock trials and
campus law societies. Mark’s passion for the law also took him abroad: he has studied at the International
Criminal Law at the University of Malta, the BPP Law School in London, England, and at the University of
Hawaii. Studying in these unique legal environments required Mark to adapt to various social, cultural, ethnic,
and economic groups, which is evident in his approach and personality to this day.
After graduating from law school, Mark practiced civil law at Bell, Ryniker & Letourneau and at Brown Sims,
P.C. In 2006, he followed his passion for criminal law by joining the team at Trichter & Murphy, P.C., where
Mark was able to study under some of the foremost legal authorities in Texas. After five years with Trichter &
Murphy, P.C., Mark decided to start his own law firm, thus opening Thiessen Law Firm.
Although his practice includes all areas of criminal defense, Mr. Thiessen specializes in cases regarding DWI,
drugs, and controlled substances. The trial of a DWI case dictates that, on any given date, a trial lawyer must be
not only well-versed in Rules of Evidence, case law pertaining to DWIs, and constitutional law, but also
numerous areas of science such as anatomy, physiology, toxicology, chemistry, computer science, biology, and
physics. Additionally, Mark has studied many hours of trial strategies in order to properly educate jurors and
judges on the sciences involved.
Mark is the current DWI Committee co-chair and on the Board of Directors for the Texas Criminal Defense
Lawyers Association (TCDLA), the 50th President and on the Board of Directors for Harris County Criminal
Lawyers Association (HCCLA) and a Charter Member and Treasurer and Director for DUI Defense Lawyers
Association (DUIDLA).
Mark’s reputation as a fearless, famous Houston attorney extends beyond his presence in the courtroom. In his
free time, he competes in Brazilian jiu-jitsu as a black belt for Brazil-021 School of Jiu Jitsu in Houston and
also trains Muay Thai. Mark is an avid snow skier, tennis player and waterman. But above all else, he loves
going on adventures with his family.
