A graduate of the University of Texas at Austin, he subsequently attended the University of Texas Medical Branch at Galveston.  He then completed a transition year residency and residency in Radiation Oncology at Baylor College of Medicine in Houston.  His undergraduate education was broken by military service, including several tours as a medic in Viet Nam.  Post college he worked for the State of Texas, functioning variably as a radiochemist, performing incident and compliance evaluations for the Bureau of Radiation Control, and eventually managing an environmental radiation assessment group. 

At 38, he decided to attend medical school (at the same time his wife Patricia, Director of the state Newborn Screening Laboratory Program, returned to school, eventually receiving a PhD in Psychology).  Post residency, he spent several years as a radiation oncologist in the Sherman/Denison area, and most recently almost 10 years in South Austin.   While working for the State, he became Board Certified in Radiation Health Physics, and is currently a Board Certified Radiation Oncologist. 

He is the author of numerous publications, abstracts and oral presentations, and is the editor of a widely distributed handbook for managing side effects in radiation oncology.   Dr Dziuk is now Director for the Southwest Regional Cancer Center Radiation Center.
