Leadership Team.

Law Enforcement Advisory Directors

A team of law enforcement officers was assembled to provide content based on real experiences from real police reports.  Due to the nature of their work, some of these officers wish to remain anonymous.  However, we can profile some of their backgrounds.

John DiGiantomasso

Technical Innovation

John discovered software development at the age of 14 and by the age of 17 was working as a professional computer programmer while a senior in high school. John continued his youthful enthusiasm for computer technology and is self-taught in application architecture and software development.

John met Dave while working at Microsoft. John joined Ken and Michael at Mitirx. After Mitrix collapsed in 2007, John was hired by Dr. Cohen to oversee ProPractice and ThinBlueOnLine.com.  John has been able to bring along the very best people from his past to form the technical team as it exists today.

On the side, John provides leadership and technical training to youth to help them better understand the workings of the real world.  He is also an avid model ship enthusiast, and runs a small business that produces wood decks for model ships.

“There are a lot of incredible benefits to being part of the ProPractice and ThinBlueOnLine.com team. First is the opportunity to work daily with some very special people. Second is the knowledge that all of these special people are working together for a special purpose – to create something that never existed before and  that can save lives on both sides of the badge. I can’t think of any other place that I would rather be.”

Ken Rudewicz

Operational Excellence

Ken began his work with technology in the supply chain field, starting as an end-user tasked with providing feedback and recommendations to the processes used in the company. This led to Ken’s role in leading operations and providing insight into customers’ needs and how they can be met through the successful implementation of technology. John served as a consultant at Ken’s company, which was the common thread that brought John to Mitrix in 2005.

Ken directs all of the day-to-day operations including client services, production, information technology, and administrative responsibilities. Ken is a key contributor to design and development of our products, calling upon his passion and vision to get the job done, and get it done right.

Ken does not have a formal technical education, electing instead to enter the world of business and gaining invaluable insights and experience directly from the workplace.  Family, technology, and participating in sports including workouts, bicycling, golf and bowling are his passions.

“I believe this product absolutely delivers what no other product I have seen can do. I have witnessed first-hand the results, and they are impressive. I come from an athletic background, so the concept of practice to improve is very near and dear to me. We also have a great group of people with similar passions and vision to help the company and products achieve the best success possible.”

David Mannion

Software Development

Dave has been developing software for over 20 years in a variety of industries, including publishing, image processing/light manufacturing, ERP systems and industrial automation.  He worked with John at Microsoft and moved up to Washington to work at the Redmond campus for several years.  He returned to sunny SoCal in 2006 to help build a SAAS/Cloud start up company, where he lead the engineering team for 7 years.

When his head isn’t immersed in code, Dave spends time with his wife and three young boys. He coaches Little League, AYSO, flag football, and basketball, and in the off-season they enjoy family bike rides, camping trips and doing home improvement projects.

“It’s great to be working with John again and with the awesome ProPractice and ThinBlueOnLine.com team.  I am passionate about building great software that provides real value to our clients.  Our technology provides a platform for delivering highly effective training that can be developed quickly and customized to our customers’ specific needs.  Our product roadmap includes cutting edge features that will transform how training is created, delivered and experienced.  Working on this technology is exciting and I can’t wait to get new features into our users’ hands.”

John Darby

Business Development

After being honorably discharged from the United States Marine Corps, John Darby pursued a career in law enforcement in the state of Pennsylvania.

As a sworn officer, John served the State of Pennsylvania Bureau of Liquor Control Enforcement, Haverford Township, and North Strabane Township.  He served as a DARE Officer teaching 6th graders, facilitated undercover operations with the BLCE, performed accident investigations, and held several positions of leadership within his department helping with training, squad leader assignments, and acting Sergeant in Charge numerous times per month.

A move to Arizona found John moving up the ranks at StormWind Studios, where he served as Vice President of Business Operations and a key member of the Leadership Team, taking StormWind from a startup to generate revenue over $100M.

Because of his background, John is perfectly suited to spread the word of the unique solution that ThinBlueOnLine.com offers to the law enforcement community.

“I like building things and watching them grow, and I have been looking for an opportunity to provide something to the Law Enforcement community that would really help them do a very difficult job.  For me, ThinBlueOnLine represents an opportunity that is really a dream come true.  I truly believe in the product that we offer, and I would be delighted to take a few minutes to tell you all about it whenever you have a moment!”

Michael An

Technology Platform

Michael changed careers – Aerospace Engineering to Information Technology focus in 2000. In 2002 worked a supply chain that led to working with John and Ken at Mitrix.

Michael is responsible for the design, implementation, and support of the production systems hosting the authoring, animation, and content environments, as well as other supplemental systems such as the development and Quality Assurance environments, including LMS test and support platforms.

Michael’s first job was providing engineering support to the Space Shuttle program.

BS from University of Maryland, MS from University of Michigan in Aerospace Engineering

“What I like best about working here are the great people I get to work with everyday.  It brings me great joy to constantly work on delivering a cutting edge technological solution that fulfills our vision and makes it possible and practical for our clients.”
