Our HistoryWestern New York's very first billing service was originally formed as PAC-DATA systems in 1979 by Charles
Tirone M.D., a radiologist and entrepreneur from Buffalo, NY. PAC-DATA utilized IBM Series - One mainframe
technology and proprietary software code to pave the way for separate physician billing and incorporated as
Medical Management Services in April, 1982.
In 1995, MMS debuted it's second generation proprietary billing system, utilizing the Ingres relational database
language and powered by SUN Microsystems.
During the 25 plus years in business, MMS has spawned many imitators and competitors.
In September of 2010, I Purchased Medical Management Services through a management buyout. MMS now
enters the next generation of service utilizing software from GE and with technology partners from around
MMS is still about service, and we succeed because of our employees.
