Shirley A. Daffin is the triage nurse for the UC Davis Vascular Center clinic. She is available to provide information and address the concerns for patients calling into the clinic. She also reviews, prioritizes, and schedules new patients based on consultations. Shirley works closely with the Vascular Center's case coordinators to provide care for patients during their clinic visits.

Daffin graduated from San Jose State University in 1983 with a bachelor's degree in nursing. She worked as a staff nurse at San Jose Medical Center in the Telemetry, ICU, and GI Endoscopy units until 1995. She developed a special interest in procedural sedation as an endoscopy nurse. In 1995 Daffin worked as a nurse consultant for the Steris Corporation, providing education and technical support for the Steris System I, an endoscope cleaning system used in Operating Rooms and GI Endoscopy units. She also continued working part time in the ICU and endoscopy units. In 1997 she became interested in interventional radiology, and provided conscious sedation for patients undergoing procedures in the radiology department at Santa Clara Valley Medical Center in San Jose.

She came to UC Davis in 2000, and worked briefly as a staff nurse on the GI/Vascular Surgery unit and in the GI Lab. She found a home in the radiology department, where nurses provide care for patients undergoing interventional procedures using the imaging modalities of fluoroscopy, CAT scan, ultrasonagraphy, and nuclear medicine.

She now transfers 25 years of nursing experience to the UC Davis Vascular Center Clinic.
