Expert Pediatric Infectious Diseases 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 diagnose and treat a wide variety of common and rare infectious diseases for children and teens of all ages—right here, close to home.   

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

What keeps me going with infectious diseases is that it is constantly changing. It is like being a detective. You are working to solve the mystery of what is causing a problem in a child, or population, and you hope to find a solution!

I love children and working with people. I hope to give the patient and their families the information they need to be empowered to deal with the disease they are facing. For patients who live far away or cannot come to see me regularly, I can also work with primary care physicians to provide a supporting framework and guidance to manage their conditions from a distance.

Pediatric Infectious Diseases

I've always wanted to be a pediatrician because it is a way for me to help both children and their families while making a long-lasting impact on their lives. I partner with families and use an evidence-based, scientific approach to develop a plan to treat illnesses that could be caused by infectious agents. 

As an infectious diseases specialist, my job is to determine if a child has an infection and, if not, to help guide further steps toward an alternate diagnosis. Most infections are treatable or will resolve on their own without treatment, so patients with infections often get better, which is very rewarding.
