"I have worked very close with Per for many years. Together we won the World Championship in racing 2017.
Per is a world class engineer, honest and hard working and with his extensive knowledge I have enjoyed every hour, year and race that we did together.
His experience with chassi, simulation and set up together with accuracy on the race tracks made it possible for us to win numerous races and championships."
Multiple STCC Champion and current World Champion
"I had the pleasure of working with Per during our time together at Cyan Racing from 2013 to end of 2017, when I left the company.
Per is one of the brightest engineers I have worked with during my career. He has a deep theoretical and analytical approach to engineering problems. Being very hands-on he has a huge amount of practical experience within the field of vehicle dynamics and race engineering which he always applies in his work. He has the ability to start from a clean sheet of paper and can specify, design, develop and introduce complete chassis systems. He is also an important contributor in developing the working methods and defining/developing support systems such as databases, CAE-tools etc.
On top of this he is a warm and caring person, straight-talking and witty with a large sense of humour. And above all – he is a true racer.
Given the opportunity I would not hesitate to work with Per again in the future and I can highly recommend him to any interested employer."

"I first met Per when I was 12-13 years old and I was doing karting and Per was working as engineer in that business at that time. I have, during the later part of my motorsport career, been able to work closely with Per. I don't know anyone with such a broad knowledge within the various areas of motorsport. Per is not only a very skilled race engineer, he also has tremendous amount of knowledge for the technical aspects in general and suspension geometries in specific"
