Who We Are?

About Us

For more than twenty-five years GSA team members have been involved in all aspects of property assessment from systems and related functions. The vast majority of GSA staff is comprised of individuals who were either employees of our Founder’s previous CAMA software company or worked directly for an appraisal district. All GSA team member have appraisal industry experience, therefore ensuring our clients receive the best possible products and support services. The GSA suite of applications are enterprise solutions that meet the evolving needs of today’s Appraisal Districts. Our mission is simple. To provide innovative assessment, tax and municipal software products with unsurpassed levels of efficiency, accuracy and client support for our government clients. In a market stagnant with older software nearing the end of their life – cycles, we are excited to offer an upgrade path for ingenious yet proven (and in production), assessment technologies.

    Our Founder and CEO, Larry Zirbel, began his career as a Research Staff Member for IBM’s TJ Watson Research Center. Shortly thereafter, he founded Software Techniques Inc. (STI) providing technology consulting in network protocol design, software development and telephony for companies including AT&T, Bell Labs, Fujitsu, and Hitachi.

    In 1994 STI shifted their focus to the Computer Assisted Mass Appraisal market,successfully producing their first tax roll in Florida in 1996. Since that time, Larry and his team have architected two additional CAMA platforms, most recently as Founder and CEO of GSA Corp, successfully producing a tax roll for Highlands County Florida’s Property Appraiser in 2018.
