I am the Medical Dosimetrist at the Shaw Regional Cancer Center.  I began my training at Henry Ford Hospital in Detroit, and became a member of ARRT in Diagnostic Radiology in 1976, and Radiation Therapy in 1977.  I have experience in treating patients from the University of Michigan, Henry Ford, and other Detroit and Michigan hospitals, but have been a dosimetrist since 1979.  My Certified Medical Dosimetrist credential was earned in 1990 from the Medical Dosimetry Certification Board.  Dosimetrists are responsible for creating computer modeled treatment plans for Radiation Oncologists, and communicating the approved plan to the Linear Accelerator, to be utilized by the Radiation Therapists.  I work closely with the Medical Physicist in data analysis, quality assurance, and treatment planning and delivery process improvement. It is my challenge to develop the best treatment plan for each patient furthering the goals of the Shaw Regional Cancer Center.
