Overview
I am married to a wonderful woman, and we have three adopted boys from Colombia, five cats, and a house full of craziness and love. My kids are the hardest and best part of my day, every day, and seeing them grow and mature into young men makes me grateful to be alive. They are my heart and my soul, and I have no words for that kind of blessing. I have always appreciated the laughter and spontaneity of children, their sweetness, their complexity, and their straightforward way of just trying to get the most fun possible out of life. I really enjoy keeping kids smiling and happy. I was recently invited to the 10-year cancer free anniversary party of one of my patients. What joy to see him grow. That helps keep me going. I am also passionate about our bone marrow transplantation program, both for children with cancer and for children with non-oncologic disease. When I was in college, I had a chance to work in a rural Mexico clinic as a translator. I was inspired by the physicians – they worked so hard, with so little, and made a huge difference for people who had no other chance. Today I enjoy helping families who need Spanish to communicate with their physician.

Nemours Children's Hospital, Delaware
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 12 conditions, according to our data. His top areas of expertise are Childhood Acute Myeloid Leukemia, Leukemia, Rhabdomyosarcoma, Osteosarcoma, and Bone Marrow Transplant.
