Together, Children’s Mercy, The University of Kansas Health System and the University of Kansas Medical Center have become the newest NORD® Rare Disease Center of Excellence. We’re joining a network of 46 other institutions bound together by the National Organization for Rare Disorders (NORD®) and our shared goals.

I’m proud to be part of an organization collaborating on faster diagnoses, expanded access, groundbreaking research and training the next generation of experts! Our partnership with KU is especially important because it helps address a gap for teens with rare diseases who are transitioning into adult care.

I’m proud to work at , where we give kids a say in their future. When a diagnosis or treatment could affect fertility down the road, our Fertility Preservation team consults quickly and clearly to help parents and patients understand the options available to them. As one of the few hospitals in the region offering tissue freezing for patients of any age, I’m grateful for this additional tool that helps patients feel in control of their own health with age‑appropriate conversations and options.

It has been an honor to chair and organize the Transition to Practice Course as the AAP Section on Surgery Education Committee Chair. Over these years, I have learned and collaborated with the very best on this committee—what an honor!

What a day! On September 26, 2025, the AAP Section on Surgery hosted its annual Transition to Practice Course, which was one of our best yet. We had an incredible 42 senior pediatric surgery fellows in attendance, which is nearly every fellow in their final year of training, coming together to learn, share, and prepare for the next steps in their careers.

Our program featured an outstanding lineup of speakers: Marybeth Browne, Reto Baertschiger, Katherine Gonzalez, Ankush Gosain, Seth Goldstein, Tolu Oyetunji, Afif Kulaylat, Jamie Harris, Alana Beres, Marion Henry, David Tashjian, Lori-Ann Rickard, and Erin Garvey. Each one shared invaluable expertise—from practice types and preparing for research, to securing the right job, navigating contracts, building financial literacy, and more.

A special thank you to all our faculty and committee members, and to Vivian Thorne, who works tirelessly behind the scenes to make these courses possible.

📌 Save the date: June 5, 2026 for our virtual session “I Have a Job, Now What?” and October 2, 2026 in San Diego for our next in-person Transition to Practice course.
