ABOUT US
Meet the PDX Biotech Team
Like you, at PDX BIOTECH INC. we work as a team, for the good of your patients and to empower your team. With over a century of professional experience across our core team and another 100+ years among our board of clinical advisors, we have had ample time to consider what we are about.
Our core values include:
- Patients first
- It takes a team
- Follow the data
- Give back to the community
We run a lean operation to make sure we can deliver OraStripdx to your team at an affordable price so the value of our test can be realized for the good of your patients.
As a team ourselves, we are from diverse backgrounds so our complementary strengths can come together to help your team communicate to your patients’ families the critical importance of oral health care to their family members’ long-term wellness.
Our company was founded, and OraStripdx was launched, because the data were just too compelling to ignore. Simply put, the thiols that we measure have been proven in clinical studies to track the progress of active periodontal disease, a lifelong condition that must be consistently managed.
From the very beginning we have made giving back a core of our identity. We have sent product around the world to those seeking to provide better oral health care. In the US we have supported rescue organizations as well as veterinary teams working with the unhoused. We have also provided product to educators of the next generation of veterinary teams.
