Meet our recent colorectal surgical fellow graduates and discover more about what brought them to Children's National Hospital, what excites them about the fellowship and what a typical day looks like.

Arianne (Ari) Maya, MD
Fellow, Colorectal and Pelvic Reconstructive Surgical
What brought you to the Children’s National Fellowship program?
I am a general surgery resident at the Medical University of South Carolina with the goal of becoming a pediatric surgeon. I have always wanted to do pediatric surgery, and as a junior resident, colorectal surgery was my second favorite rotation, so I thought coming to work with a world renowned pediatric colorectal team during my academic development time as a resident would be a great way to augment my training and develop my research background.
What excites you about this program?
This program is exciting because it allows me to develop my clinical research skills while also working on my clinical and surgical skills. It has been equally exciting to get to see the same patients over and over as most of our patients follow with us for months and years after their surgeries. I have really enjoyed getting to know the patients and their families and see how well-coordinated, multidisciplinary care can really change their lives.
When your fellowship program ends, what do you hope to do after?
I plan to return to the Medical University of South Carolina to finish my general surgery training and apply to pediatric fellowship. I hope to have pediatric colorectal surgery be a large part of my practice as I have thoroughly enjoyed learning about and treating patients with colorectal problems.
Where are you from?
I am originally from Fort Lauderdale, FL, and went to undergrad and medical school at the University of Florida. (Go Gators!) Before starting this fellowship, I was living in Charleston, SC.

Keon Young Park (KYP), MD, PhD
Fellow, Colorectal and Pelvic Reconstructive Surgical
What brought you to the Children’s National fellowship program?
I was drawn to Children’s National for its internationally recognized pediatric colorectal program and strong emphasis on multidisciplinary care. Training in a high-volume, collaborative environment with leaders in the field made it an ideal fit for my clinical and academic interests.
Where are you from?
I was born and raised in Seoul, South Korea, and moved to Ann Arbor, MI, during high school. I have since trained at several institutions across the country before coming to Washington, D.C., for fellowship.
What is most exciting to you about this program?
I truly value our program’s commitment to multidisciplinary care for children with complex colorectal conditions. I love the opportunity to collaborate with and learn from surgeons from across the country and around the world dedicated to helping children with complex colorectal conditions.
When your fellowship program ends, what do you hope to do after?
After fellowship, I plan to pursue a career in academic pediatric surgery with a focus on colorectal conditions, with an emphasis on multidisciplinary care and improving long-term patient outcomes.
