Why Horizon?

In the beginning, our CEO Tim Walbert had a vision for a different kind of pharmaceutical company.

One that challenges industry norms, embraces innovation and puts patients first. It’s a vision that we carry forward today. It’s at the very core of our culture. It’s who we are.

It’s Personal

All of us at Horizon believe that we aren’t just employees, we and our loved ones are patients too. We do what we do because it’s ingrained in us; it’s in our DNA. Whether we’re developing and marketing medicines, supporting patient advocacy efforts or giving back to the community, it’s personal.


Award-Winning Culture

While we’ve grown at a rapid pace, our culture remains rooted in its personal, small-company feel.
We’ve consistently received recognition as one of the best places to work at both the local and national level.
