DR. THEODORE MARENTIS is a Radiologist at Dignity Health. He completed his residency in radiology at the University of Michigan at Ann Arbor.

Born in Athens, Greece, Theodore's family came to the US for the first time in 1996 and he became a naturalized citizen in 2004.

Theodore completed his MD at the Harvard University and Massachusetts Institute of Technology Health Sciences and Technology program. He received his BS in biomechanical engineering and MS in electrical engineering from Stanford University, graduating Phi Beta Kappa and Tau Beta Pi.

At Stanford University, Theodore was active in community service with such organizations as Habitat for Humanity and the Urban Ministry. He was the chairman of the community service committee for his fraternity. His research on Micro-Electro-Mechanical Systems (MEMS) has been published three times. Theodore's immediate goal is to produce an implantable liver dialysis machine. He is the co-inventor on a renal dialysis patent and believes that medicine is the perfect confluence of his passions for science and technological development and his desire to have a positive social impact.
