Since 2011, Hans has been responsible for the delivery of operational objectives at YRCI, including service lines such as Human Capital and Human Resources (HR) Services, Acquisition Management and Financial Management services. Hans provides executive leadership, guidance, and direction in forging and maintaining long-term relationships with our current and emerging customer base of Government clients, including Department of Defense (DoD), Federal-civilian, intelligence community programs, and commercial/industry customers.

Hans is a visionary who designed and staffed more than 500 FTE operations of YRCI’s Corporate PMO office and YRCI’s innovative Remote Operations Center (ROC™), where a shared services delivery method is utilized for HR and Acquisition support services to 19 federal agency clients. To develop the ROC™ as a strong shared services center with its own workflow and performance metric tracking systems, Hans utilized an array of IT skills and his in-depth understanding of shared service and contact center designs including; Unified Communication Applications, Customer Relationship Applications and Case Management, Data Center Design, Computer Networking LAN/WAN, Database Applications, E-commerce initiatives, Computer Telephony/Interaction Management Applications and Software as a Service / Cloud/Application Service Provider Offerings, and HRIS inclusive of HR-Applicant Tracking systems.

Hans has selected and organized his team to achieve superior, consistent client satisfaction, a tall order in the mission-enabling service areas YRCI supports. There is both a skills gap as well as a workforce shortage in the federal market, specifically in the HR Staffing area. To address this issue, Hans created the YRCI Learning Management System (LMS) and University, YRCI’s trademarked training and certification program that demands successful on-the-job application of the skills being taught. Additionally, Hans created an intern program in the HRROC™ that allows recent graduates to serve as apprentices to retired SES and GS-15 level operational experts in their respective fields. As a result, YRCI has been able to grow our own talent and retain a high performance workforce even in a demanding environment.

Prior to coming to YRCI, Hans was serving the role of Executive Vice President of Sales for The LYNX Group, Inc. and Director of Sales for Computer Network Systems, Inc. Hans earned a B.S. degree in Accounting, and has completed a vast array of studies at the graduate level including Environment Science and Policy at Johns Hopkins University, and History, Geography, and Archaeology within the University of Maryland system.
