Our work
A 20-year partnership with Fitzpatrick Translational Science
For more than twenty years we've worked alongside Fitzpatrick Translational Science to build the software behind their work with leading pharmaceutical companies: hundreds of web applications, each solving a specific, hard problem for the teams that use it.
We also designed and built Fitzpatrick Translational Science's own website. Visit their site
“For more than twenty years RizTEK has built the software behind our work: hundreds of tools that our pharmaceutical clients and their patients use every day. When we bring them a hard problem, they don't just build what we asked for. They figure out what we actually need, and they're still there when it has to change.”
