Your Local, Personalized, Colorado PEO

Denver-based InTANDEM HR is local and personalized – and we like it that way. Some PEOs offer inflated cost savings at the proposal stage in order to make a sale. And when there’s a problem, no one can be found to help. That’s just not our way at InTANDEM HR. We pride ourselves on real cost savings, quick response times, and our deep-held belief in always making it right.
