Dacorum Strategies

Copy of About

Passion. Experience. Diligence.


Dacorum is a name blended with the word "Decorum" meaning - behavior in keeping with good taste/propriety" and "Arete" which is the Greek word meaning - the excellence of any kind.  And that is exactly what the team at Dacorum Strategies™ brings to every engagement; excellence in good taste to ensure lasting success!

Since Legalization began of cannabis (marijuana and hemp), our founders have worked tirelessly on two very different sides of the equation, but both keenly tuned in on public health and safety, consumer protection, and building an industry following the rule of law. 

Todd Mitchem and Donald Rosier met when Don was a sitting County Commissioner for Jefferson County Colorado, and Todd operated within the marijuana industry as a lead consultant for government affairs/community outreach for one of the largest brands in the industry, The Green Solution. Right away their similar interests as well as expertise in a variety of professional settings,settings made them the perfect team to take these industries to the next level. Each with a  personal connection and passion to seeing both cannabis and hemp flourish in the mainstream; they made a decision to join forces and build Dacorum based on their shared principles for collaboration, excellence in business, and an overall focus on strategic outcomes.

It all began with the idea that government and community efforts could best operate with reason, strength, diplomacy and a sense of excellence for each client. Dacorum's team all believe in this same philosophy.
