Because for Us, It’s Personal

Many of us are patients, know a patient or have been impacted by a patient story. This deep appreciation fuels every decision we make and shapes who we are. By pushing ourselves to live up to our own potential, we are helping others live up to theirs.

Our Values


We value collaboration. Trusting each other and tackling tough challenges can make a powerful difference.


We do what’s right for our patient communities through quality decisions and owning our successes and failures.


We fiercely innovate and evolve to better ourselves, our communities and our patients.

These resources, including monthly manager check-ins, formal trainings, mentoring and networking opportunities, guarantee that learning and development remain top of mind for all. Additionally, we offer frequent instructor-led sessions for our employees and managers on various topics, including developing Horizon’s core competencies, leading others and inclusive leadership.

At Horizon, we know that disease does not discriminate. We embrace the bold ideas of one another, foster a sense of belonging and value diversity.
