It’s important that the treatment experience is as personal and comfortable as possible for every family. Our department has its own Family Advisory Council whose input helped bring lots of improvements – like room service, refrigerators, prayer groups, better food, and better access to social support. Making life easier for these families is a huge priority for me. Even sick kids are kids at heart (as I am), just looking for a smile, some fun, a connection with the team members who take care of them. I make it my business to make life better for these kids and their families – as a doctor and through research into promising new drugs. I’m a firm believer in clinical trials. In fact, about 80% of our patients are enrolled in clinical trials through the Nemours Center for Cancer and Blood Disorders, and the Nemours Center for Childhood Cancer Research, where I’m director of both. This number is much higher than for adults with cancer, and much higher for children with other kinds of diseases. We also participate in the national Pediatric Preclinical Testing Program, which makes new therapies available for kids sooner. In our department, participating in clinical trials and research studies is the standard of our family-centered care. Dr. Kolb is highly rated in 15 conditions, according to our data. His clinical expertise encompasses Childhood Acute Myeloid Leukemia, Acute Myeloid Leukemia (AML), Leukemia, Rhabdomyosarcoma, and Bone Marrow Transplant. Dr. Kolb is currently accepting new patients.
