Our Mission is to educate and equip our clients with sustainable solutions that add value to the economy, society, and environment.

Our Shared Vision

We strive in every personal and professional contact to influence and enhance a deeper understanding of what it means to protect and preserve the environment and the health and safety of the people within it.

Affinity is more than just another company; it is an idea – an idea of what companies should stand for and how they should operate. It is based on the concept that it is much more difficult to be relevant than it is to be successful – that relevancy supplants success on the path to opportunity.
