Our Mission
Ventegra is

A force for good.

Ventegra was created with the intention to ensure appropriate use of prescription drugs while lowering our clients' costs through innovative programs and products. As a Certified B Corporation, we are part of an elite tier of businesses that hold each other accountable to maintaining a balance between purpose and profit.

Ventegra is a force of good

We are proud to be at the forefront of corporations that implement initiatives that benefit not only stakeholders, but society as a whole. For us that means we:

  • Eliminate hidden margins and spreads commonly seen with traditional Pharmacy Benefit Mangers (PBMs).
  • Help uninsured and underinsured populations have greater access to affordable healthcare.
  • Provide employees with paid volunteer time off ("VTO") so they can be active in their communities and focused on causes that hold personal significance.
  • Maintain a low carbon footprint by operating virtually as we have done for years.
  • Support nonprofits such as the National Multiple Sclerosis Society, Orangewood Foundation, and the Illumination Foundation.
