Edgar Dibble

Job Titles:
  • Owner
I have over 30 years (yes, I'm old) of business experience owning businesses or in the corporate world. Why did I decide to open a drug testing lab? Because I want to make sure our world is a safe place to live and do business. Besides, does anybody get into this business to collect urine? When I'm not collecting sample, I love sports - playing or watching. Nowadays, I watch more than I play.
