We are a relatively small practice with a small staff and a single physician focusing on personalized individual care.  We have done our best to make our office comfortable and inviting for children and their families.  We recognize that children often develop their illnesses at odd times, and we do our very best to see every child with an urgent problem on the same day that the parent calls.  We try to separate our sick patients from our well patients by leaving our afternoons loosely scheduled so that parents calling in with a medical problem can be worked into the schedule in the later afternoon.  We try to bring our healthy children into the office for well-child or follow-up care in the morning and early afternoon so that they are not exposed to sick children coming in later in the day.


We place a heavy emphasis on teaching healthy lifestyles as a way to prevent long-term chronic disease problems later in life.  We believe that immunizations are essential for both the individual and the community, and insist that our patients be fully and appropriately immunized.  We understand that we live in a highly technical age, and we commit to explaining our thinking and decision-making behind any diagnosis or recommendation we may make.  We make a point of explaining the self-limited nature of most diseases in children, and consequently we have a very low rate of prescribing antibiotics compared to most of the medical community.


We provide comprehensive well-child care from infancy through adolescence.  We manage most common medical problems in children, and seek local or university level consultation as needed.  We offer prenatal consultations for expectant parents, and we offer extended consultation hours at the end of the day for families whose children have complex medical issues or where there is a need for the entire family to meet together to receive medical advice.  We do minor surgical procedures such as repair of lacerations and wound care, as well as routine circumcision.


After hours advice is available both weekdays and weekends by calling the office telephone number and making the appropriate selection to speak to the physician on call.


Dr. McCormick sees patients only at St. Joseph's Hospital newborn nursery, emergency room, and pediatric inpatient service.  He does not see patients at other hospitals in the community.

Our Doctor
Charles R. McCormick, MD, FAAP

Dr. McCormick was born in San Francisco and was raised in Marin County during the 50s and 60s when Marin was still a quiet rural county, and it was normal for children to roam the hills and collect lizards and snakes and the occasional scorpion.  In the fall of 1967 he left Mill Valley to go to UC Davis to start his college education.  Between his sophomore and junior years at Davis, Dr. McCormick worked for the California Department of Fish and Game and then traveled in Europe for three months.  Returning to school the following year, he went on to graduate in 1972 with a degree in Wildlife and Fisheries Biology, and then went on to medical school, staying in Davis at the UC Davis School of Medicine where he graduated in 1976.  After a three-year residency in pediatrics, Dr. McCormick moved to Stockton to become the first Medical Director at the newly formed Valley Mountain Regional Center.  Two years later, Dr. McCormick joined an established pediatric practice with Dr. Eugene Lamazor and has been practicing primary care pediatric medicine ever since.


For the past 13 years, Dr. McCormick has been in solo practice at the current location, striving for that happy blend of technical expertise in the electronic age coupled with the old-fashioned kind of personal relationships that were normal before group clinic practices with many rotating providers took over.


Dr. McCormick is married and has three grown children and one grandchild.  He has always been a physically active person and has engaged in several different sports at different times in his life.  In high school he played on the tennis team.  In college, he was captain of the fencing team.  After moving to Stockton, he raced sailboats and was actively involved in the Stockton Sailing Club where he developed the community oriented "Learn to Sail" program that has been teaching children how to sail their own small boats for the past 19 summers.  In the mid-1990s, Dr. McCormick returned to his greatest athletic love, fencing, and competed at the national and international level until injuries in 2002 and 2003 prevented him from competing actively.  Now an official senior citizen, Dr. McCormick gets onto the tennis courts as often as possible and plays at a recreational level.

She has been married to her husband Stephen for over twenty wonderful years and has four children — two boys and two girls. Janet obtained her Bachelor’s in Liberal Studies from Humphrey’s College.

She attended local schools, and in 2012 graduated from Heald College with an Associates of Applied Science in Medical Assisting.
