Meet the Team

Andersen Staff Photo

Our people are our most valuable resource

Even, or perhaps especially, employees not profiled on this page. In addition to the people making it happen in leadership and sales, we also have dedicated individuals bending metal, building crates, filling gas ampoules, crafting accessories, maintaining the grounds and buildings, servicing our machines in the field, taking customer calls and shipping orders.

Employees below work for Andersen Sterilizers unless otherwise noted.
