Adolescent Medicine

Adolescence is an exciting time of growth and discovery. Teens and young adults have unique needs, both physical and emotional. Some patients have complex and multidisciplinary conditions that can’t be met in the primary care setting.

CHOC’s experienced team of board-certified adolescent medicine specialists helps teens and young adults navigate difficult issues. Our specialists are highly skilled and have resources to care for high-risk patients from 12-21 years of age. The team works with the family, while respecting the teen’s desire for confidential care.
