They took the time to not only look at our existing computers but also spent time discussing our future agency management system...to ensure we would be installing a network system that would meet our future needs.....A Truly consultative approach to business.

Palisades Development Group LLC

We found ourselves in a situation where our current IT group was unable to deliver the level of service and expertise we required and we were less than thirty days from the Grand Opening of our first Hospitality location with a second to follow in ninety days. Our network needs are fairly complex; with centralized property management systems and accounting, complex interfaces for Hotel based systems and back office reporting, full PCI compliance, and management in the field requiring access to various systems from wherever personnel happen to be at any given time.

Additionally, we went from about twenty network and email exchange users to nearly a hundred in a matter of weeks. This was closely followed by the need to convert to better accounting software, convert to an email exchange including blackberry enterprise, and add terminal server accessibility.

Castellan has a unique depth and breadth of expertise and continues to be our partner in the development, design, and implementation of multiple projects.
