A Culture of Passion and Purpose

While software is our passion, people are our purpose and we pride ourselves in innovating technology that humanizes healthcare. Although we have evolved over the years, we wouldn’t be where we are now without our commitment to making “healthcare efficient, accessible, and affordable for everyone.” Our success not only comes from our inspiration to foster real relationships but is also driven by the loyalty of our outstanding customers who we consider to be a part of the Raintree family.

Help Us Humanize Healthcare

It is our charge to humanize healthcare. That’s why we strive to conduct business for the common good by leveraging technology to deliver high-quality healthcare that highlights the WHO while working on the WHAT.
