About the Trak Team

We are a team of scientists, engineers, software developers, and business professionals. More importantly, we are fathers, mothers, brothers, sisters, and friends who care deeply about improving men’s reproductive health and helping people start their family.

Founded in 2012 in part by government scientists from Sandia National Laboratories. Sandstone’s mission is to provide innovative, data-driven tools to help men assess, manage, and improve their reproductive health.
