Office Manager

Mavenspire is an Annapolis, Maryland-based IT advisory and engineering firm. Founded in 1999, we deliver SMARTaaS — Smart People as-a-Service — combining strategy, engineering, and managed services to solve complex technology problems for governments, manufacturers, legal services firms, and commercial clients.
