About Us

PST was invented and developed starting in 1988, by Bob Musser, a former Navy nuclear engineer, who fell in love with computer programming while serving our country.


Since that day, Bob has created a team of developers and technical support staff that continue to make PST the leader in the industry.


You’ll find Bob and his team at most state and national association meetings – please come and say hi! We’d love to meet you and hear your suggestions for PST!
