Authenticity
At Summus, people bring their real selves to work – their passions, their beliefs, and their smarts. And the result is not only a workplace filled with lively debate, but also a true marketplace of ideas where solutions can come from any team member.
Accountability
While everyone at Summus has personal reasons for wanting to make expertise more accessible, our real commitment is to each other, our members, and ultimately, to not just imagining better access but ensuring we each do our part to make it happen.
Excellence
If the transformation Summus is leading was easy, it would have been done already. Innovation requires the very best of every one of us. Every day. And that kind of excellence is exactly what we deliver for our clients, our physician partners and for each other.
