DC Preventive Forensics
DC Preventive Forensics is not a commercial forensic or compliance consultancy. In DCPF, a number of specialists joined forces, each with decades of experience. Each of us individually is a specialist in the fight against involvement in crime. We noticed that in national and international training courses, lectures, and educational colleges in which we were individually involved, we had a personal connection, but also a similar view on how to ensure that knowledge about how both organizations and individuals could arm themselves against involvement in crime.
After we left the work process, we received many requests to continue sharing our knowledge. Because we are all collaborators, but also all complement each other from our own expertise, we decided to join forces in DCPreventive Forensics.
We would like to share relevant articles, knowledge, but also our personal visions with you. But we also want to seek cooperation with organizations and individual initiatives that play a role in the fight against involvement in crime.
We share our knowledge and experience via this website. But you can also contact us for individual help and support with a specific question about prevention, but also for lectures and training. Regardless of whether this is for commercial or non-profit organizations, or a company charged with (formal) supervision or it concerns the further enforcement chain up to and including prosecution.
One thing is paramount for us. We are all collaborators and always create a customized product together with you, in which we will see the knowledge and input of all of us in both the design and the realization. In which, in addition to (technical) substantive aspects, policy, administrative, managerial, communicative, etc. aspects will also play a role.
Roy, Hans, Diego en Ton


Diego Crijns
is an experienced national and international speaker, writer and trainer on crime topics. In fact, Diego always gives workshops in which theory is linked to his own experiences. Diego uses many examples from his own 20 years of supervisory experience as a tax accountant and (policy) lawyer. But also almost 25 years of national and international (FATF) experience in investigation and prosecution and also as a lawyer in financial and economic criminal cases as well as his current work as a Judge in appeal court specifically for these type of crimes.
Diego’s workshops are always full of current examples so that the knowledge transfer does not remain theoretical but can be immediately made concrete. Or in his own words: I want to offer the participants nails on which they can hang their own examples, not only current but also future ones.”

Roy Appels
is an experienced national and international speaker on themes and topics surrounding crime, seizure and confiscation. Roy gives workshops that link theory and practice based on his own experiences. It is important that knowledge transfer does not remain theoretical but can be made concrete by the participants based on practical examples. He uses many examples from his more than 26 years of experience as a public prosecutor. But also from his experience as deputy director of the FIOD (Dutch tax and financial police), police officer and in recent position as parttime Judge in appeal court.

Ton Scholing
Swiftly after finalizing his study as an accountant at the tax authority accademy, Ton switched to the FIOD (Dutch tax and financial police). In addition to experience as a detective and assistant public prosecutor, he became a project leader and team leader, often on new and special topics. For example, he was the first head of the FEC (Financial Expertise Centre where governmental parties join there FE-effort), but also project leader of the first team on the financing of terrorism after the 9-11 attacks. His most recent activity was at the AMLC (Dutch knowledge Centre on money laundering) and was partly responsible for shaping the fight against money laundering in the Netherlands. Ton’s knowledge and experience lies not only in combating crime, but also in managerial aspects.
Ton is driven by a combination of expertise innovation and effect.
His contributions are therefore characterized by a combination of managerial and criminological aspects based on the many Do and Don’ts that he can share from his own experience.

Hans van Boggelen
Hans has a long-term employment history in IT and cybersecurity, giving him a somewhat different profile than the other team members.
After various roles in smaller IT companies and an adventure with his own company, he switched to IBM almost 30 years ago, where as a senior solution consultant he has shaped complex solutions for a huge range of different types of companies and in different markets. He was able to look deeply into many ‘kitchens’. Over the past 10 years, the focus has quickly shifted from IT outsourcing to AI and Cybersecurity. The rapid changes in these fields and the assessment of the opportunities and risks thereof are a constant source of inspiration for him.
Hans will particularly explain the impact of technological and/or cybercrime developments in our areas of interest.
