Our mission.

Our mission.

We're on a mission to help everyone have happier and healthier hands so they can do what's important to them.

Heart and science.

Heart and science.

We started out to help our grandfather — our amazing Papa — hold his morning cup of coffee without feeling any pain. So, we put our brains to work, using our biotech and medical backgrounds to come up with a solution. We ended up creating something that went beyond our family. This was something for every hand, for every day, for everyone.

This first invention was the ZenGrip Mug. It didn't stop there. We're trying to help everyone's hands feel their best. We offer free hand workout classes and videos, and sell many wonderful products, all designed for your hands.

And that just feels good. Which is exactly what we're all about.
