Sandy Diaz O’Donnell, PA-C

Meet Sandra “Sandy” Ileana Diaz O’Donnell: a certified physician assistant who has been practicing dermatology in the San Gabriel Valley for the past 29 years—with no plans on stopping any time soon!

Sandy’s favorite part of dermatology care is getting to know all of her patients on a personal level and building lifelong relationships around the specialty that she loves. She treats her patients like family, and she welcomes anyone that would like to join her ever-growing family. Sandy is well known in the community for her dedication to her patients. She is very happy to stay in the Pasadena/Arcadia communities to continue to dedicate her time to taking care of patients of all ages.

Sandy is married, has 4 adult children, and 5 beautiful grandkids. When she’s not in the office, she is spending her time playing with her grandkids in Los Angeles and Miami.

Sandy is fluent in both Spanish and English.
