Philosophy of Care

It is truly a great privilege to provide care for children with acute needs in the fields of hematology and oncology. This area of medicine has advanced through cooperation and sharing of information and novel therapeutics. I believe in open and direct communication with families on a regular basis to empower families so that as a team we can help to provide the best possible care for their child.
