Our Approach
Criterion is built on the idea that superior service and quality in medical physics consulting should be a given.
The consulting field can vary widely in skillset, pricing and level of quality. We strive to be a trusted partner to our clients – reliable, informed, and transparent. We also want to have fun while doing this. We have a serious responsibility in the work we do, and we take great pride in that, but we believe there’s also room for learning together, making it interesting, and getting to know one another.​​
