Castle Biosciences

Company Overview

ABOUT CASTLE BIOSCIENCES INC.

Castle Biosciences is improving health through our innovative tests that guide patient care. For the diseases that our portfolio of tests covers, we believe the traditional approach to developing a treatment plan for cancers and other diseases using clinical and pathology factors alone is inadequate and can be improved by incorporating the personalized information our tests provide. Our innovative tests for skin cancers, uveal melanoma, Barrett's esophagus and mental health conditions provide personalized, clinically actionable information to clinicians and patients to guide treatment decisions and improve health outcomes. At Castle, we aim to transform disease management by keeping people first: patients, clinicians, employees, and investors. Since our inception in 2008, we have remained focused on this vision. This foundational strategy remains the guidepost for the direction of our company and the basis of our long-term value creation. Castle Biosciences Inc, ranked #188 by the Financial Times, Americas' Fastest-Growing Companies 2023.

Castle Biosciences is an Equal Opportunity Employer/Veterans/Disabled.

Company History

Castle Biosciences was founded in 2008, by Derek Maetzold who believed that traditional methods to determine cancer patients’ prognosis could be improved by newly emerging techniques in molecular biology. We continue to focus on transforming disease management in areas of unmet clinical need through the development and marketing of innovative diagnostic and prognostic tests that guide patient care.
