Our Story

Back in July of 2002, from the basement of their DC townhome, Sumi and Dominic decided to start a company that focused on leveraging data to support public health. Dominic used his 15 years of data management experience to draw up the vision for CORMAC. They chose the name CORMAC — the Gaelic word “charioteer” — to reflect our ability to navigate challenges with speed and agility.

Since then, CORMAC has continued to hone our expertise in health data management and analytics. In doing so, we have led the design of multiple systems for our biggest customer, the Centers for Medicare and Medicaid Services (CMS) under the U.S. Department of Health and Human Services (HHS). Our dedication to data has fueled our long track record of success, and we are constantly challenging ourselves to go above and beyond for our customers — always keeping data at the heart of our work. We are passionate about using data to improve the U.S. healthcare system as we know it.

CORMAC’s innovative and flexible culture gives us the freedom to use our skills to best solve our customers’ problems. We empower each other to be at our best, most creative, and most resourceful.

We keep it simple with the three I’s:

  • Integrity — staying true to who we are as a company and empowering people with data. Letting our work speak for itself.
  • Innovation — constantly striving for new ideas and approaches to face challenges head-on.
  • Inclusion — fostering a diverse workforce that supports and celebrates each other as a team. We make sure we all have access to opportunities and resources to contribute to CORMAC’s success.
