Kevin Karch
Overview
Kevin Karch is a veteran software developer and entrepreneur whose career spans more than five decades—from IBM mainframes and punch cards to modern AI-assisted billing platforms.
As co-founder of K&K Systems, he combined deep technical expertise with business vision to create one of New York’s most respected medical-billing service and software firms.
Early Technical Career (1968–1974)
Kevin began his computing career at Grumman Aircraft (Bethpage, NY), working on the IBM System/360 Model 75 and Model 67 mainframes. Starting as an operator apprentice on the midnight shift, he quickly advanced to lead operator on the day shift, managing VM on the 360/67—his first exposure to virtual operating systems. During that time, Kevin developed proficiency in JCL (Job Control Language) and Roscoe, which he used to automate JCL script generation. He transitioned into programming in COBOL by 1974.
Turning Point & Founding Years (1974–1985)
In 1974, Kevin met Sue, a fellow programmer, and the two began a lifelong professional and personal partnership. By 1981, they were married and working together on early microcomputers, including the IBM PC, developing software for healthcare clients. Their first project automated the HCFA-1500 insurance form for a Montauk chiropractor—an innovation that sparked the birth of K&K Systems. The company’s foundation was laid in the Karch family’s Commack kitchen while Sue was pregnant with their son Keith (born 1984).
Growth & Expansion
While serving as Software Manager for Brooks Fashion in Manhattan, Kevin oversaw a transition from mainframe-connected IBM 3150/3270 terminals to standalone IBM XT and AT systems with expanded memory and storage. Meanwhile, the K&K platform spread through word-of-mouth and professional associations—particularly the New York Chiropractic Association, whose early endorsement helped drive adoption across the state and, eventually, the country. By attending regional medical conventions and seminars, Kevin and Sue built a national client base for their software solutions.
Over time, K&K evolved from a pure software vendor into a full-service medical billing provider, specializing in New York Workers’ Compensation and No-Fault claims.
The company’s success was built on decades of technical excellence and close relationships with physicians and attorneys, ensuring fast, compliant, and accurate claim processing.
Today, K&K Systems is recognized for its niche expertise, longevity, and family-driven stability.
Legacy
Kevin’s professional journey bridges multiple eras of computing—from IBM punch cards and COBOL to Windows-based billing networks and now AI-assisted automation.
With over 50 years of continuous innovation, his story reflects both a passion for technology and a commitment to integrity, family, and enduring client relationships. The business he built with Sue stands as a rare example of a homegrown enterprise that remains technologically advanced, financially strong, and ready for its next chapter.

Susan’s consulting spans the full revenue cycle: analyzing billing and coding, tightening documentation, optimizing accounts receivable, and mapping processes that maximize reimbursements. She is particularly experienced in New York No-Fault and Workers’ Compensation cases, where precise forms, timelines, and payer rules are critical to successful outcomes.
Beyond client work, Susan has extensive experience with health-provider audits and computer forensics investigations performed for the FBI and the U.S. Department of Justice. She has also served for more than 15 years on the Advisory Board of Branford Hall Career Institute, assisting with the medical billing curriculum and mentoring students—regularly offering externship opportunities that help candidates earn accreditation and launch their careers.
