Dr. Tom Grogan set out on a path to change the practice of medicine 32 years ago when he founded Ventana Medical Systems, Inc., now a global leader in cancer diagnostics that was acquired by Swiss-based Roche Group in 2008. The company provides more than 250 cancer tests with related instruments for delivery to over 90 countries to improve patient outcomes, making the company the leading supplier of cancer diagnostic systems to the pathology market.
Roche Tissue Diagnostics is regarded as a diagnostics pioneer, evidenced by the over 900 patents issued globally. In addition to changing the practice of medicine globally, Dr. Grogan and his wife, Cande Grogan, have made a lasting impact locally as philanthropists, supporting causes that include the University of Arizona, local arts organizations and the Women’s Foundation of Southern Arizona. His latest book is "Chasing the Invisible: A Doctor’s Quest to Abolish the Last Unseen Cancer Cell."
