our vision

What drives us?

365CustomCritical is a service of Post Communications. 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.

The headmaster 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 headmaster, 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 headmaster 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 headmaster 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.

Don’t take our word for it…

These guys really get it. They look for creative solutions and deploy them with seemingly effortless simplicity, all the while listening to what we actually need. All of this, of course, puts us at ease and lets us focus on what we do best – teach our students. Thank thank thank you.

One of the many things that separates Post Communications from every other service provider we have used is their enormous knowledge and experience across non-profit organizations of every type and size. Their insights are immeasurable, and their hearts are even bigger than their brains. They all but eliminated our frustration with technology, and they saved us LOTS of money in the process. They are masters of hand-holding and their ability to train users of all abilities is worth the ticket price alone. We are already ready to renew our contract…
