During much of Dr. Shillingford's time at CHLA he has served as the director of the Pediatric Pathology Fellowship program. Under his stewardship the program has consistently achieved a board pass rate of over 90% and has produced some of the most capable pediatric pathologists in the region.  Nick also serves as site director for pediatric pathology training of USC residents, a rotation that has consistently received much praise on resident evaluations. Nick's service to residents is extended beyond USC to local institutions through lectures and interactive sessions in pediatric pathology, an activity that is much needed by programs without a robust pediatric pathology service. These efforts have led to an increase in the interest in pediatric pathology amongst general pathology residents as evidenced by an increase in the number of local residents on electives at CHLA as well as an increase in applicants to pediatric pathology fellowship programs nationally.

Given his strong interest in medical education Dr. Shillingford has delivered numerous lectures to medical students at Keck and has facilitated even more interactive laboratory sessions. His teaching and fund of medical knowledge has drawn scores of students to his sessions and has influenced many to participate in the pediatric pathology shadowing program.

Nick's commitment to education is also extended to foreign trained medical students who wish to practice pathology in the US through an unofficial observership program offered at CHLA. Over 95% of trainees who have participated have successfully matched into a residency training program.

On the clinical front Dr. Shillingford receives consistent praise from clinicians for his superb diagnostic skills and pathology leadership has been provided with very positive feedback about his work. His input is often sought after in instances where cases provide a diagnostic challenge. Clinicians and pathologists at local institutions also seek his opinion.
