Expert Pediatric Gastroenterology 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 our community’s children with expert comprehensive care for a wide range of digestive, liver and nutritional disorders—right here, close to home.  

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

Sarika Aggarwal, MD

Pediatric Gastroenterology

I love that my work gives me the opportunity to connect with the entire family and make a difference in their lives. We work as a team to provide compassionate, personalized care with empathy. I see patients with a variety of gastrointestinal conditions, including abdominal pain, constipation, nausea, vomiting, eosinophilic esophagitis, dysmotility, IBD and others. I also have a special interest in treating patients with nutritional disorders such as failure to thrive, short gut syndrome and tube feedings. Since every child is unique, each child requires an individualized treatment plan. My goal is not only to treat the child but also to educate the child and his or her family about the condition. When everyone understands the plan of care, we have a greater chance of success.

David Garcia, MD

Pediatric Gastroenterology

As a first generation Mexican American, Dr. Garcia’s family only spoke Spanish. He saw the barriers first-hand that his family faced at doctor appointments, which is why he loves seeing the smiles on his patients’ faces when they discover he speaks Spanish and can feel confident that they’ll understand each other. Most diseases that Dr. Garcia treats are life-long conditions. So, building a trusting, long-lasting relationship with the family is a top priority for Dr. Garcia. While he treats all gastrointestinal disorders in children, Dr. Garcia has specific clinical interests in Celiac Disease and Eosinophilic Esophagitis.

Emily Stryker, MD

Pediatric Gastroenterology

It's a privilege to help sick kids get back to normal as much as possible. Some patients just need a little bit of extra help, and some have incredibly complex issues. Whatever it may be, I want to be there for them. Every patient deserves that focus and attention. I want families to know I am dedicated to working with them to come up with a course of treatment that is going to bring them some peace and comfort for their child.

Pediatric Gastroenterology

In working with families, I prioritize open communication and collaboration. Understanding their concerns allows me to tailor care effectively. Given the interconnected nature of gastrointestinal conditions with overall health, I aim to provide comprehensive support to patients and their families, addressing the physical, emotional, and mental aspects of health.
