“Success is not what you do,
but rather what you do for others.”

David Delgadillo, a graduate of USC School of Medicine, joined Desert Orthopedic Center in 1995 following his academic achievements and several years of experience. He assists Dr. Adrian Graff-Radford who specializes in total hip and knee replacements as well as complex revisions and knee arthroscopies.

“The ability to practice medicine and make a positive impact on people’s lives, makes this all worthwhile,” he comments.

Born in Texas and moving to California in his early childhood, Delgadillo completed his Bachelor’s degree in Biology at California State University, Dominguez Hills in 1990.

While at USC, he graduated with honors in primary care and surgery.  David completed all rotations including general and orthopedic surgery.

“Working with a top notch surgeon is great.  Following the patient in the pre-operative phase and post-operative follow-ups as well as the surgery is invaluable.”

David adds, “There are many physician assistants who either work in the office or in the
operating room setting which is great, but doing both is the best.  This allows me to see the patient pre-operatively, assist in the surgery and follow the patient through in the hospital, the post operative and recovery period.”

David also helps with organizing surgery coverage for other surgeons and PAs at DOC.  As a senior PA, he has helped increase the visibility of PAs in the community.

David is board certified by the NCCPA (National Commission of Certification of Physician Assistants) and a fellow of the American Association of Physicians Assistants as well as a member of the California Academy of Physician Assistants.
