JASON VARGAS, MD, FAAP
I love being a private practice pediatrician. I have had the privilege to care for children and families and watch them grow at my practice, Cactus Children’s Clinic in Glendale, Arizona since 2004 and I hope to do it for many years to come. I have been able to cultivate my interests in child advocacy, child safety, and caring for children with special needs, including Down Syndrome.
I have been able to be a part of training pediatric residents, nurse practitioners and physician assistants in my office. I have been able to work with community hospitals and as a board member for Phoenix Children’s Care Network working to integrate the private practice pediatrician’s role in providing quality pediatric care for years to come. I hope my interests and experience can help in some way to support our mission to improve health care for children.
I graduated from San Jose State University and Stanford University before my residency at the University of Washington-Seattle Children’s Hospital. I was born and raised in California but moved to Arizona in 2004 with my wife after her residency in Anesthesiology. We have 2 children and a dog. We love traveling with our children, running, and spending time with family and friends.
