Notes

Following Mother’s Medical Legacy

William S. Loui followed directly in his mother Florence Chinn Loui’s footsteps by:

  • Becoming a physician like his mother
  • Attending the same medical school (John A. Burns) where she worked and where her memorial scholarship now helps students
  • Practicing in Hawaii where his mother maintained her practice for 58 years
  • Serving on the American Cancer Society board (his mother was screening education coordinator)
  • Teaching at the medical school (Assistant Clinical Professor)

Poignant Specialty Choice

William’s specialty in oncology and hematology is particularly meaningful given that his brother Terrence Loui survived childhood brain cancer at age 7 (1966). Terry’s experience with:

  • Experimental high-dose radiation
  • Inoperable brain tumor
  • 41 years of survival beyond 5-year prognosis

…may have influenced William’s decision to specialize in cancer treatment and blood disorders.
