What’s in a Name?

Lexern Law Group was founded with a clear purpose and a singular promise - to share our deep expertise in business and employment law with the business owners and employees who need us most. Our name embodies this very concept. “Lexern” is a combination of the Latin word “Lex” (meaning “law”) and “Ern” (a derivative of “earn” or “be worthy of”). We create long-term relationships and treat our clients with the compassion, respect, and admiration they deserve. We like to think that Lexern Law Group offers a rare combination of legal knowledge as well as honest and practical legal advice that our clients just won’t find anywhere else.
