Dr. Denise O’Riordan loves kids. Her professional training has been in pediatrics—at the Oakland Children’s Hospital and then as an urgent care pediatrician in San Mateo. Currently, she practices with Blackhawk Medical Group. Dr. O’Riordan chose pediatrics as her specialty because she enjoys not only working directly with children, but also their families. She encourages parents to ask lots of questions. Dr. O’Riordan is board certified by the American Board of Pediatrics. When Dr. O’Riordan is not working, she enjoys spending time with her husband and her own children.
