About Manquen Vance

For over a decade we have perfected a customer service model that addresses the demanding needs of public sector. This model and the innovative marketplace strategies we deploy for public sector are just as relevant today to service the needs of private sector employers. Moreover, there are tremendous opportunities for private sector and public sector employers to collaborate and work together to address the challenges surrounding the oversight and management of healthcare plans. We have changed our name to Manquen Vance as part of our current business strategy to reach private sector employers and offer them our current best in class services.
