I believe that all children deserve a chance to grow and develop and reach their maximal potential. I make every effort to educate and support the parents and caretakers of children with developmental disorders, since they are the real experts when it comes to their own child.

As a developmental pediatrician, I evaluate and monitor children with known or suspected problems such as developmental delay, speech and language delay, mental retardation, attention deficit/hyperactivity disorder, learning disorders, autism, and genetic disorders. I also help to monitor the developmental progress of premature babies and other children at higher risk. I provide the expertise and backup to help assure that children with developmental disorders have an effective and comprehensive "medical home" with their primary pediatrician.

Having been a practicing general pediatrician for many years, my focus is on helping pediatricians to detect children who may have developmental problems, and to coordinate their care.

I graduated from Princeton University and received my M.D. degree from Penn State University's Hershey Medical Center (yes, where the chocolate factory is!) in 1977. I then went on to complete my pediatrics residency at the Children's Hospital of Philadelphia. I completed a fellowship in Developmental Pediatrics at Oregon Health Sciences University in Portland, and have lived west of the Rockies ever since, including California and the Northwest. I spent eight years as a solo pediatrician in Hilo, on the Big Island of Hawaii, the rainiest city in the U.S. I moved back to California and joined Kaiser Permanente in 2005.

Roles and Responsibilities

In addition to my clinical practice as a Developmental Pediatrician at Kaiser Santa Clara, I also have a regional role as co-director of the Northern California Pediatric Developmental Disabilities Office which is based in Oakland.
