During our annual CHOP It Up! Summer Cooking Camp, our patients with chronic kidney disease participated in hands-on cooking lessons, preparing kidney-friendly meals while learning how to manage salt, potassium and other dietary factors that can cause issues when kidney function is impaired.

Registration for our next fall cooking workshop, in partnership with the Culinary Literacy Center at the Free Library of Philadelphia, is now open to our nephrology patients: http://ms.spr.ly/6188a5uZp.

Throughout 2026, we’re celebrating the many “firsts” that have made CHOP a world leader in pediatric healthcare. Today, we’re highlighting CHOP’s first woman CEO, Madeline Bell.

Madeline began her career at CHOP as a bedside nurse in 1983 and went on to hold a number of leadership roles before being named CEO in 2015.

As CEO, Madeline led CHOP through one of the most transformative periods in its history. She oversaw the expansion of the CHOP Care Network and the Philadelphia Campus; the creation of the Middleman Family Pavilion, the Roberts Center for Pediatric Research and the Morgan Center for Research and Innovation; and the development of the Center for Advanced Behavioral Healthcare, the Behavioral Health & Crisis Center, and Roberts Children’s Health, a new inpatient complex that will open in 2028.

Madeline has invested in cutting-edge science that led to breakthroughs like the first personalized gene-editing therapy and the first gene therapy for congenital blindness. She has advocated for policies that advance children’s health and created community programs that reach thousands of families throughout our region. And she has built a team of more than 33,000 workforce members who share her commitment to CHOP’s mission and values.

At the end of this month, Madeline will retire after nearly 40 years at CHOP. We are deeply grateful to her for her visionary and compassionate leadership – and for the remarkable legacy of breakthroughs she leaves behind.

Meet Ezra, our one-year-old patient who recently started learning how to walk. This may seem like an ordinary milestone for a toddler, but it's a special one for Ezra's family. Ezra was diagnosed at birth with metachromatic leukodystrophy or MLD, a rare genetic disorder that affects how children grow and develop. Babies with MLD appear healthy at birth, but around ages 1 to 2, they begin to lose the skills they once had. However, a new gene therapy can stop or slow the damage caused by MLD, but only if the treatment is given before symptoms begin.

Ezra traveled from West Virginia to our hospital to receive the gene therapy before symptoms began, and we are thrilled to share he's reaching his milestones and doing great!
