Business Philosophy

Conventional wisdom says that most companies need computers to succeed in today's fiercely competitive business environment.True enough - as far as it goes. Unfortunately, the simple presence of a dozen or so computers in your small company won't mean much - unless they are used to their full capacity.

But what exactly does full capacity mean? And how can you achieve it without spending a fortune?

That's where Castellan comes in. Most systems integrators start by telling you what you need to solve your communications problems and end by selling you expensive systems you probably don't need.

Not Castellan. We begin by listening to you explain how your business operates, what its communications problems and bottlenecks are, what needs to be done to make it more efficient - and therefore more profitable.

Only after learning all this will we suggest solutions to your communications problems. Solutions that will be within your budget. Solutions that will fit your company's operation. Solutions that will work.

Then we'll create a plan - specific to your business - to implement those solutions. We'll also recommend hardware and software, work with you during installation and on training your people, and help you get your communications system up and running.We'll also offer you a support plan so that we can be available to answer your questions and to help with troubleshooting.
