About AOS

From the beginning, we partnered with our customer to align business objectives with the right technologies to meet the desired results, such as: maximizing effectiveness, improving customer satisfaction, and increasing profitability.

AOS has built its foundation upon a time proven approach for success that starts with Account Managers that are students of the industry supported by Design Architects, each a subject matter expert focusing on a chosen technology practice.  Our certified Project Managers oversee the deployment of customer solutions, keeping the implementations on time, in scope, and on budget, in conjunction with our highly specialized certified Systems Engineers and Solutions Trainers.  The outcome is nothing short of a quality solution that meets the pre-established objectives of our customer.  

AOS places the highest priority on responsive and professional customer service with integrity.  That approach is responsible for AOS’ growth from three employees to now exceeding 350+ employees in 9 states.  Our expertise has changed since 1992 to become much broader and more specialized, but AOS has never lost focus of core values that made us successful.

Every customer has unlimited access to our highly available Help Desk that provides the ultimate in client support 24 hours a day 7 days a week, with the ability to deploy a local Systems Engineer at a moments notice.

“Our customers expect the best from AOS vs. others that are just average at everything. With that in mind, we have specialized into very specific practice areas.”
