Our Mission

IMD Path we are a Molecular Diagnostics Laboratory investing in the technology, information systems and business infrastructure enabling community based Pathology groups in their diagnostic mission and empowering Oncologist in both First Line and Advanced-stage cancer management of their patients.

We presently operate two facilities in Berkeley CA and Aurora CO. These labs represent our template for functional and strategic alignment in support the “local” immediate diagnostic needs of our patients as enabled by our PSI Berkeley CA regional lab, bolstered by IMD’s Academic level Esoteric Center of Excellence in Anschutz Medical Campus at the University of Colorado…IMD’s “hub and spoke” model of care for Oncology.

At IMD “value based care” is not a marketing term but to our founders, investors, collaborators, and dedicated staff’s continuous mission to define, quality care as…achieving positive patient outcomes at reasonable cost!

We aim to simplify a complex system through integration of the commercial laboratory business model to independent pathology groups.
In order to provide top of the line and consistent results, we invest in Molecular Diagnostics Laboratories supported by an academic level medical expertise.
Through the empowerment of symbiotic relationships to ultimately improve patients navigation of the Oncology experience in targeted treatment.
