What our subscribers tell us:

I've always paid slight attention to your articles but one thing I realized during my studying for the DUIDLA Board Certification exam (when I really paid attention to your articles) was that there is A LOT of really good information in your journal that is extremely helpful to my practice in general.
    - Reid D., Colorado

"I have been going through some of the volumes.  Lots of good materials. Very helpful.  I’ll be happy to share Counterpoint with my colleagues..."
    - Michael S., Pennsylvania 

"Just wanted to start off by saying your journal is fantastic and I use it all the time to study in my field of DWI defense.  Keep up the great journal work."

    - Bryan O., Texas

"I’ve been a student member for two years, and was already overwhelmed with the value, but only in the past few days have I begun finally reading the Counterpoint Journal articles. They are tremendous. The specific article that compelled me to write this email is “An Introduction to Retrograde Extrapolation” by Deandra Grant.

I don’t yet really understand the science — I’ll have to read it several times when I’m less tired. But the article lays out what I really need even if I don’t fully get the science — exactly how to expose this pseudoscience that I instinctively know it to be to a jury. Thank you Deandra Grant and Jan Semenoff. I am now assisting a great Delaware criminal defense attorney, and because of you, I should be truly useful to him, and ready to go out on my own before long. You cut years off the learning curve. Thanks again for your incredible labor of love. Lawyers without this information are handicapping themselves."
     - Patrick W., Delaware


"We intend to work hand and hand to make Counterpoint extremely useful to our members, and synergistic with DUIDLA endeavors to provide educational benefits and resources."
    - Tim Huey, Ohio
       DUIDLA Past-President (2018)

"
Thank you for all that you do. I love the way Counterpoint is written, and I love the idea behind its development. I am preparing for the DUIDLA Board Certification Exam, and I will be studying the journal articles. Again, thank you."
   ​- Jim B., Texas

"I have found the articles to be very informative and easy enough to understand when I am sitting in court. They also help give me a starting point in conducting further research for cases. I just wanted to thank you for putting this journal together and all of your hard work and energy you put into it."
   - Joseph D., Florida

​
"If you're not a subscriber to Counterpoint, you're missing out on some great research and commentary."
   - Joseph M., Virginia

"​
I thoroughly enjoyed every article... Your method of explaining, recapping, and reinforcing scientific concepts in an easy to understand format, replete with illustrations, is as good as it gets."
   - James B., Texas

​"Counterpoint is unique. It is the only publication out there that deals with what I do in my practice on a day to day basis"
   - John C., Arkansas

"This is perfect! You can't write this stuff fast enough. Please keep cranking out these articles. Honestly, I could've used this article yesterday"
   - Chuck R., Minnesota

Jan Semenoff, B.A., E.M.A.

Forensic Criminalist
​Editor in Chief

Picture
Jan Semenoff is the principal editor of Counterpoint and is well-known across Canada and the United States as an experienced Forensic Criminalist. He has testified as an expert in breath alcohol testing, SFST, and DRE issues in more than 150 jury trials, and has presented at more than 100 state, national and international conferences. He has been teaching science to professionals since 1986. He officially founded our parent company, Industrial Training & Design Ltd. in 1995. His ability to make complex scientific and forensic concepts understandable has made him a sought-after speaker in North America. ​
With a career spanning over 18 years in policing, Jan Semenoff is a recognized expert in breath alcohol analysis and DUI investigations. His work has made him a sought-after consultant and expert witness, having provided testimony in more than 150 court cases across North America. Jan is a well-respected authority on DUI investigations and the intricacies of alcohol-related offenses, regularly advising legal professionals and other forensic specialists.
​Before transitioning to his current role as a Forensic Criminalist and educator, Jan served as a Primary Care Paramedic, an experience that has greatly informed his understanding of emergency response and the practical application of medical knowledge in forensic contexts. His background in emergency medical services allows him to bring a unique perspective to his work, particularly in cases involving intoxication and impairment. 
​He has collaborated with lawyers, scientists, investigators, investigative reporters, and toxicologists across Canada and in dozens of jurisdictions across the United States, bringing a fresh perspective to the science involved in legal practice. He was the principal technical advisor to The New York Times in their year-long investigation on breath testing deficiencies in North America, and has been interviewed by numerous national media outlets, including newspapers, radio, and television.
​In addition to his practical expertise, Jan is a dedicated educator and trainer. He designs and delivers specialized adult education programs aimed at enhancing the knowledge and skills of legal professionals, forensic experts, and health and safety specialists. His courses cover a range of topics, including breath alcohol testing, workplace safety (with a focus on chemical handling and exposure), and the development of effective workplace policies and procedures.
​As a highly regarded speaker, Jan is frequently invited to present at regional, national, and international conferences on topics related to forensic matters, DUI investigations, and occupational health and safety. His ability to translate complex technical subjects into clear, actionable insights has made him a popular choice among conference organizers and participants alike.
​In addition to his speaking engagements, Jan serves as an editor and contributing author to Counterpoint, a science journal dedicated to the intersection of legal and technical fields. His contributions to the publication have solidified his reputation as a thought leader in the forensic science community.
​Currently, Jan serves as the Secretary on the board of the International Association of Forensic Toxicology Consultants (IAFTC), further cementing his leadership role in the global forensic toxicology community. He is an Associate Member of the International Association of Chemical Testers (IACT). His commitment to advancing the field, along with his extensive practical experience, continues to make him a trusted expert in his field.
​Jan Semenoff's career reflects a deep commitment to excellence in forensic investigations, education, and the advancement of safety and policy within both the legal and occupational health arenas.
