The Occuscreen Team

Peter Mack |Founder and CEO

Peter founded Occuscreen in 1991, after working in Occupational Healthcare and seeing a need for cost-effective drug testing for employers. Soon employers were asking for services beyond drug screening, such as criminal background checks, DOT administration and occupational health services (physicals and vaccinations). From the very beginning, Occuscreen has been committed to providing excellent service while helping employers nationwide hire with confidence.

Peter also runs a northwest high school A ‘Capella competition (Rose City Sing Off), and volunteers for the Portland Rose Festival Foundation. In his spare time he runs the occasional marathon and drinks the occasional glass of wine. Peter has 3 kids and 4 grandkids who make him smile every day.
