Dr. Denise Riordan of Blackhawk Medical Group

Denise O’Riordan, MD

At Blackhawk Medical Group since 2012

I love kids.  All of my professional training has been in pediatrics—at the Oakland Children’s Hospital and then as an urgent care pediatrician in San Mateo before joining Blackhawk.

I chose pediatrics as my specialty because I enjoy not only working directly with children but also their families. I encourage parents to ask lots of questions.  We get to know each other well and develop a real relationship.  Because of my specialty, I have the great privilege of playing an important part in the health and development of the next generation—from newborns up to young adults.

When I am not working I enjoy spending time with my husband and my own children!
