We are bringing research to new communities and expanding access to care.

The Site Partnership Network supports traditional site models with an embedded team of experienced research professionals at sites within community healthcare reaching diverse patient populations that are less saturated.

Site Partnership Network

We provide an extensive and diverse funnel of trial opportunities to investigators directly from our partners, CROs, and sponsors, effectively bringing research into communities where care is provided by the health care providers they trust most. Where access to clinical research typically isn’t available, we’re equipped to bring trial opportunities as a care option in historically underrepresented communities.
