Our  Story

Adolescents may seem to be the healthiest people on earth, but the fact is they have unique health and wellness needs that are often overlooked. And that can put them on a trajectory for health issues affecting every aspect of their adult lives.

For more than four decades we’ve known that too many young people in New York and the nation have too little access to the high-quality, specialized, vital care they need. And that there is a calculable impact on the vitality of their communities, the city and country. We know that the health and resilience of young people isn’t a luxury for a strong society. It’s essential.

That’s why we’re here.

The Mount Sinai Adolescent Health Center was established in 1968 by Dr. Joan Morgenthau, a Mount Sinai pediatrician who recognized that adolescents needed the privacy and comfort of their own health care space, outside the intimidating façade of a hospital. With the humblest of beginnings—its first home was a trailer in a parking lot in East Harlem—the Center was the first program in New York, and one of the first in the United States, devoted to the special health care needs of teens.

We’ve grown since then to a staff of more than 100, and our approach has evolved to stay up to date with what it means to be a teenager in a changing world.

Our center is the largest of its kind in the United States. Our team of specialized professionals is devoted to the 11,000 young people, ages 10 to 22, who come to us for every kind of health and wellness care: Primary, sexual and reproductive, mental health, nutrition and fitness, even dental and optical. We provide all these services under one roof—and without regard to our patients’ ability to pay. No young person is ever turned away or billed. We treat all who come to us with compassion, respect and confidentiality.

Our model is now recognized nationally for breaking down economic and social barriers to health and wellness care for young people who need it most. Our team is widely respected for developing a unique model for delivering the highest quality, inter-disciplinary services, with proven results. As an integral part of the Mount Sinai Icahn School of Medicine, we train the next generation of adolescent specialists and offer highly sought-after post-residency fellowships. And we conduct pioneering clinical research in areas that are vital to the health and welfare of young people.

It’s all about our core belief that young people need to be physically and emotionally healthy to make it in this world, and that high-quality care is their right—and our responsibility.

A Special Kind of
Adolescent Care

Comprehensive, teen-friendly, developmentally appropriate.

Tangible Results

Our adolescents are more likely to graduate high school and college.


Without charging, we provide all our services for $1,000 a year per patient.

“The Mount Sinai Adolescent Health Center helps young people thrive, and we need more of that in this country. If we can come in early and help them live healthier lives, we will increase graduation rates, decrease the cost of care later on and build stronger communities. The human and financial cost of not intervening is far too big.”
