Kevin Karch
Kevin Karch is a veteran software developer and entrepreneur with over 50 years of experience spanning IBM mainframes, early personal computers, and modern AI-assisted billing systems. He is the co-founder and Software Architect of K&K Medical Billing Systems, one of New York’s most established medical billing software and services firms.
Kevin began his career in the late 1960s at Grumman Aircraft in Bethpage, NY, working on IBM System/360 mainframes. Rising from operator apprentice to lead operator, he gained early experience with virtualized systems, JCL automation, and enterprise computing before transitioning into COBOL programming in the early 1970s.
In 1974, Kevin partnered professionally and personally with fellow programmer Sue Karch. Together, they embraced the emerging microcomputer era, developing healthcare software on the IBM PC. Their breakthrough project—automating the HCFA-1500 insurance form—led to the founding of K&K Medical Billing Systems in 1981.
While managing large-scale system transitions as Software Manager at Brooks Fashion in Manhattan, Kevin continued to expand K&K through professional referrals and industry associations, including the New York Chiropractic Association. The company steadily grew into a national presence through conferences, seminars, and word-of-mouth adoption.
Over time, K&K evolved into a full-service medical billing provider, specializing in New York Workers’ Compensation and No-Fault claims. Its reputation is built on technical precision, regulatory expertise, and long-standing relationships with physicians and attorneys.
Kevin’s career reflects a rare continuity across generations of technology—from punch cards and COBOL to Windows networks and AI-driven automation. The business he built with Sue remains family-run, financially strong, and technologically current—positioned for its next chapter while grounded in decades of integrity and innovation.
