Adolescence is that period of life during which a child develops into an adult. Many rapid changes occur physically, emotionally, intellectually and socially.
The Adolescent Medicine team is a group of experienced medical professionals that provide specialized medical care to teenagers. We provide care that the teen’s primary care provider may not feel comfortable in treating and managing. We manage and treat many adolescent issues in males and females, including those related to normal puberty, growth and development, psychosocial development, some behavioral issues, menstrual issues, sexuality, sexually transmitted diseases, eating disorders and diagnostic dilemmas.
We are committed not only to treating disease, but also to helping teens develop healthy lifestyles and habits through guidance and education. We are also committed to supporting parents in their efforts to guide their children through what are sometimes turbulent years.
Our diverse team is trained in a broad spectrum of specialties, but sometimes our patients need more specialized attention. We have access to all the specialties at SSM Health Cardinal Glennon if necessary.
To make an appointment, please call 314-268-6406.
