Our Pediatricians

At Silicon Valley Pediatricians, we consider it both a great joy and a great responsibility to care for children. Most of us are parents ourselves, so we strive to be understanding and available to the families we are privileged to serve. We are honored that you have chosen us as your child’s primary medical provider and are confident that you will be pleased with the quality of care and service that we can provide for you and your family.

A vital part of our service to children begins with our outstanding staff, who works hard to manage and maintain a professional, caring and supportive environment for our patients in a timely manner. Our doctors are lifelong learners. Not only have they received advanced medical training in pediatrics, they continually pursue ongoing education to stay abreast of the latest in child health care.

Christine Halaburka, MD

Christine Halaburka, MD, is a board-certified pediatrician with admitting privileges to Good Samaritan Hospital and El Camino Hospital – Los Gatos. She is on the voluntary clinical teaching staff of Lucile Packard Children's Hospital Stanford. After having her first two children, Dr. Halaburka returned to school and received her bachelor's degree in biochemistry with honors and distinction in general scholarship from the University of California, Berkeley. She then attended Stanford Medical School, where she did research in pediatric endocrinology and taught anatomy and endocrinology. She remains, however, a diehard Cal Bears fan! She began her residency at Stanford University in 1987 as a single mother of two teenagers. It was during her first year of residency that she met her husband, a widower with two young boys. They married and moved to Los Gatos, where she adopted the two younger boys. She then sadly was left widowed herself when her husband passed away.

Two of Dr. Halaburka's children have served in the Peace Corps, and she likes to apply the Peace Corps' job description to parenting: "The hardest job you will ever love." Her joy of traveling with her patients' families on the magical journey of parenting keeps her energized and eager in her job, and more so every year. Along with teaching parents how to avoid the common pitfalls of parenting, she also greatly enjoys teaching the fresh new doctors coming up through the ranks. Dr. Halaburka has the true love of children and parenting. She thrives on sharing that love and enthusiasm with her patients and their parents. In her spare time, Dr. Halaburka loves to spoil her grandchildren and is an accomplished jewelry artist.
