Expert Pediatric Hematology/Oncology (Cancer) Care—Close To Home

For parents in Contra Costa County and surrounding communities, having a child with a complex medical condition used to mean spending lots of time traveling all over the Bay Area for visits with children’s specialists. 

Through our collaboration with Stanford Medicine Children’s Health, we provide comprehensive and personalized care for children and young adults diagnosed with cancer and blood disorders, including those conditions requiring stem cell transplantation—right here close to home.  

In addition to your pediatric hematologist/oncologist, your child’s care team may also include nurses and other healthcare providers—all who have advanced training in specifically treating children and teens.

Louise Lo, MD

Pediatric Hematology/Oncology

I love my job because I love children, science and being challenged. Children are inspiring for their innocence and resilience, and families are inspiring as they empower themselves with knowledge and understanding to care for their sick child. I have been fortunate to witness advancements in the science of hematology and oncology that have generated exciting, new and effective treatments. Because of these advancements, I can provide our families with hope for the future for their child—something that most people don't expect in pediatric hematology and oncology. I feel very privileged to help guide and support families through what can be a very difficult journey.
