Over the past 30 years, John Tredennick has spoken before more national and international audiences on legal and technology issues than he or anyone else can remember. He has written and edited five best-selling books and countless articles on litigation and technology issues. He is one of a small number of people who pioneered the e-discovery industry.

In 2013, the American Lawyer named him among the six most important  "E-Discovery Trailblazers." He has also been named one of the "Top 100 Global Technology Leaders" by London's CityTech magazine and to the 2012 FastCase 50, which recognizes 50 of the smartest, most courageous innovators, techies, visionaries and leaders in the law. Tredennick also served as a member of the Short Course Faculty at the University of Virginia Law School, where he taught the course, "Electronic Discovery in a Global Environment" and he regularly lectures at other law schools and e-discovery training programs.


John began his career as a trial lawyer and litigation partner with one of the largest law firms in the Rocky Mountains. He got interested in technology in the late 1980s when his wife brought a computer home for graduate business school. After erasing the data on her hard drive twice, and making lots of other mistakes, he began to see promise in the machines. Working with a team of technologists, he began building software to help his 10-office firm manage complex litigation.

In 1995, John became the firm's chief information officer (CIO), the first in the country for a major law firm. He also continued his full-time practice as a trial lawyer and litigation partner. His passion for finding ways to use technology to improve law practice led the firm to international prominence as a technology pioneer. It also led to a 1999 induction into the Smithsonian Institute Archives as an Information Innovation Pioneer.


John and his team began building web-based litigation repositories in 1998, while still a partner at his firm. He founded Catalyst (originally called "CaseShare") in 2000. The company has since grown to more than 100 employees worldwide. The company is headquartered and maintains multiple data centers in the U.S. and Japan, with representatives in major cities across the U.S. and Asia.

Over the years, John and the company have won numerous awards. Among his many honors, John was named Rocky Mountain Entrepreneur of the Year by Ernst and Young and Technology Entrepreneur of the Year by the Colorado Software and Internet Association. Catalyst was named Top Company for Technology/Media/Telecommunications by ColoradoBiz Magazine and Colorado Company to Watch by the Colorado Office of Economic Development. It has also been named repeatedly to the Deloitte FAST 50 and FAST 500 (for rapid growth) and received recognition by Socha-Gelbman and Law Technology News as a Top eDiscovery Provider.


In 1990, John was editor-in-chief of the best-selling, multi-author, two-volume book, Winning With Computers: Trial Practice in the Twenty-First Century, both published by the American Bar Association. That same year, he and his partner Bob Benson wrote, How to Prepare for, Take and Use a Deposition, for James publishing. In 2000, John wrote The Lawyer's Guide to Excel, which was published by Glasser LegalWorks (now Thomson). An updated version, The Lawyer's Guide to Excel 2007, was published by the American Bar Association in 2008.

John is the former chair of the American Bar Association's Law Practice Management Section. For many years, he edited Law Practice Management, a monthly ABA magazine focusing on legal technology and management issues. More recently, he founded and edited Law Practice Today, a widely read ABA Webzine that focuses on electronic discovery and other legal technology and management issues.

John has two children. An important member of John's virtual team is his show-jumping horse, Glory B. Together they've papered John's office with blue ribbons and action shots from competitions across the country. (It's not just in the courtroom where John enjoys a good win!)
