Drawing on extensive experience in the administrative law arena, Mr. Lyons is also involved in a multitude of administrative proceedings, including proceedings before the EEOC and the Colorado Civil Rights Division, as well as multiple business and professional regulating agencies.

These roles include the opportunity to draft, edit, and amend personnel handbooks, manuals and policies, as well as presenting regular training programs for the employees and managers of clients.
