#1 In Food and Beverage.
Now In Cannabis.

For the last 30+ years, Dennis Group has worked exclusively in the food and beverage market, designing production systems - and the buildings that house them -  for almost every conceivable market segment. Cannabis processors are manufacturing products ranging from flower, extracts, oil, distillates, concentrates, edibles, topicals and infusions. Each one has different processing and packaging requirements, and you need an engineering partner who has the experience that is well matched with your operations. 

With 500 employees spanning eight domestic and global offices, we have the resources you need. We can do small-scale studies, full turnkey ground-up greenfields and everything in between. Plus we have specialized capabilities such as automation, packaging integration, and system modeling  - all under one roof.
