A Farewell from Dr. Thornburg

A Farewell Letter from Dr. Thornburg

Dear San Diego Bleeding Disorders Community,

It is with mixed emotions that I step down as the Director of the Hemophilia and Treatment Center (HTTC) at Rady Children’s Hospital San Diego. I accepted the position of Chief Medical Research Officer, Division of Blood Diseases and Resources (DBDR) effective April 21, 2024. In this role I will provide leadership, strategic planning, and detailed oversight and management for research on the causes, prevention, and treatment of blood disorders so that people with blood disorders have better treatments and quality of life. I will really miss this community but hope to stay engaged at local events.

I am transitioning the leadership of the HTTC to an amazing group of physicians.

I hope our paths will cross again. Wishing you good health and happiness.

Best wishes,

Dr. Thornburg
