our vision

What drives us?

365CustomCritical is a service of Post Companies. The lifeblood of our company is our desire to serve. Because we work with organizations of every size, our team has a robust knowledge of the fundamentals of service – responding to the needs of those around us by listening to and observing what is actually happening. We are experts in leadership, planning, implementation and management of information technology systems and services because we listen.

The head of my high school used to describe three kinds of citizens: those who drop a piece of trash and keep walking, those who drop a piece trash and pick it up, and those who see a piece of trash dropped by someone else and run to pick it up.

So obsessed with trash was this head of school that a group of seniors one year piled up old cans and bottles and strung them all together with fishing line. As a prank, they strategically placed the pile of trash on his route to work (he walked from his house to school every day), and upon seeing the bottles, the head of school increased his pace as he walked intently towards the bottles to pick them up. At the appropriate signal, one senior hiding behind a bush pulled the string to move the pile of trash. Without missing a beat, the head of school ran faster, chasing the bottles as they rattled around, gliding across the grass. Nothing would stop him from picking up that trash. This man lived by example, modeling how he expected his students to behave, even if in a comically obsessive way.
