the Quadax difference
A Legacy of Experience, Built for What’s Ahead
For decades, our clients have relied on us for more than technology. Independently owned and accountable for results, Quadax combines proven healthcare expertise with an award-winning platform and a team invested in your success. Together, we deliver the resilience, intelligence, and support needed to keep revenue moving.

What We Do—and How We Do It
Operate with certainty. Quadax delivers revenue cycle management solutions for healthcare organizations navigating constant change with zero margin for error.
We partner with hospitals and health systems, laboratories and pathology groups, physician groups, and specialty providers to connect workflows across patient access, claims, denials and appeals, reimbursement, analytics, and patient engagement. Our technology gives teams greater visibility, automation, and control, supported by dedicated experts invested in their success.
Backed by more than five decades of healthcare experience, we combine technology, intelligence, and accountable partnerships to prepare organizations for what’s next.
Five Decades of Knowing What Comes Next
Established in 1973 by Ralph Daugstrup and Tom Hockman, Quadax emerged from their work together at IBM, grounded in a clear and enduring belief: complex systems demand disciplined thinking, accountability, and foresight—a belief that has guided the company for more than 50 years.
Following Tom’s passing in 2025, his legacy continues to guide Quadax. We honor his longstanding leadership as Chairman of the Board and CFO. Ralph, who passed in 2023, remained a trusted advisor long after retiring in 2005. Their lasting contributions, steady leadership, and dedication to clients are embedded in how Quadax operates today and will always be remembered.
We are privately held by choice, giving us the independence to answer only to our clients and do what is required without compromise.
