Our Partnerships

Wostmann & Associates provides services directly to federal, state and commercial clients. However, in some cases there is a need for specialized skills or knowledge to best serve the client. We are a firm believer in partnerships to provide more comprehensive services to clients while maintaining the agility of a small firm. We partner with firms in and out of Alaska with specific expertise who also share in our commitment to quality. At the same time, we remain independent from specific product solutions and will recommend what we believe to be the best fit for the client’s system environment and organization.

Our longest-running partnership is with The Alaska IT Group, a joint-venture originally formed among a group of Alaska’s leading technology service providers to offer more comprehensive services and scale to serve the needs of the State of Alaska. Today, this group includes Wostmann & Associates, Inc, PangoMedia, Network Business Systems (NBS) and Software North LLC. For several clients and projects we have partnered with Borderhawk for information security, and PeopleFirm for business transformation and change management.
