I’m Jacqueline Winkelmann, M.D., known to many as “Doctor Jacq.” I have been a hospital-based pediatrician at CHOC Children’s since 2001, and my hospital’s most recent Chief of Staff. I have a passion for children’s health, well-being, and safety. I am a pediatrician, advocate, a dedicated home chef, and mother of two.

My passion for healthy cooking, combined with my firsthand experience dealing with two young elite level athletes, set me on a path to discover the unique nutritional requirements of young, high-level athletes.  It became my personal mission to educate parents, coaches and young athletes on the unique nutritional requirements of being a growing, developing child/adolescent while putting their bodies through the rigor of high-performance training. I founded Doctor Jacq: Nutrition Coach for Young Athletes in 2014 and have since worked with thousands of parents, coaches and young athletes.

Based on my experiences with newborns, new moms and young children at the hospital, I have become a strong voice for any and all products targeting our children and new moms. I have been very active speaking and writing to ensure children’s safety and well-being is the number one priority of product companies geared to infants, babies, and children. I have recently partnered with several product companies to ensure children’s safety and well-being is their number one priority, and to help educate new parents as they embark on the adventure of parenthood.
