Ana Maria Arbelaez, MD
Dr. Arbelaez joined the St. Louis Children’s Hospital staff in 2005 and serves as an Instructor in Pediatrics in the Division of Endocrinology and Diabetes at Washington University School of Medicine. She completed her pediatric residency training at St. Louis Children’s Hospital followed by a fellowship in pediatric endocrinology and diabetes. Dr. Arbelaez maintains an active program in general endocrinology and diabetes with specific research interest in hypoglycemia associated with the treatment of diabetes and cystic fibrosis-related diabetes.
Abby Hollander, MD, Clinical Director
Dr. Hollander joined the Division of Pediatric Endocrinology and Diabetes at Washington University School of Medicine in 1992 and serves as an Associate Professor of Pediatrics and Director of the Division of Pediatric Ambulatory Medicine. Her pediatric residency was completed at the Children’s Memorial Hospital in Chicago, Illinois. She is a graduate of the Fellowship Program in Pediatric Endocrinology and Diabetes at St. Louis Children’s Hospital and Washington University School of Medicine and is board certified in pediatrics and pediatric endocrinology. She is currently on the Clinician Educator Track. Her clinical interests cover all aspects of pediatric endocrinology, including growth disorders, thyroid disorders, pubertal disorders, adrenal disease and diabetes.

Dr. Hollander is a member of the American Academy of Pediatrics, the American Diabetes Association, the Endocrine Society and the Lawson Wilkins Pediatric Endocrine Society. Dr. Hollander has been involved in several clinical research projects. Over the past five years, she has presented information at national meetings regarding the molecular variants of growth hormones, the use of insulin pumps in children, and complicated presentations of type 2 diabetes in adolescents. She has been an investigator in exciting multi-center studies that are looking at new therapies in diabetes mellitus, growth hormone deficiency and hypothalamic obesity. She is working with Neil White, MD, to define the risks and benefits of insulin pump therapy in children with diabetes.

Dr. Hollander is very involved with the local chapter of the American Diabetes Association, and has been a member of the Camp Committee, Youth Group and the Board of Directors. She has been a Diabetes Camp Physician since 1990 and became Medical Director of the camp in 2001.

Dr. Marshall’s clinical interests include diabetes and all aspects of endocrinology and metabolism. She is a fellow of the American Academy of Pediatrics and a member of the Lawson Wilkins Pediatric Endocrine Society, the European Association for the Study of Diabetes, the International Diabetes Federation, the American Diabetes Association, the Endocrine Society, and is a charter member of the American Association of Clinical Endocrinologists. She is board certified in pediatrics and pediatric endocrinology.

Dr. Marshall’s research interests include intermediary carbohydrate metabolism, glucose transporter structure and function mechanisms of insulin resistance, and metabolic control of insulin secretion. She has been funded by a National Institutes of Health Clinician - Investigator Development award, the Hardison Family Foundation and the National Institutes of Health NIDDK. She has been a scholar of the Child Health Research Center of Excellence in Developmental Biology at Washington University.

Neil White, MD, CDE
Dr. White is a Professor of Pediatrics in the Division of Pediatric Endocrinology and Diabetes at Washington University School of Medicine. Dr. White received his MD Degree from Albert Einstein College of Medicine. He completed his post-graduate pediatric and pediatric endocrinology training at St. Louis Children’s Hospital and then served as an Assistant Professor of Pediatrics in the Division of Endocrinology and Metabolism from 1980-1987. From 1987 to 1991, he served as Associate Professor of Pediatrics and Communicable Diseases at the University of Michigan School of Medicine, and as Associate Director of the Clinical Implementation Core of the Michigan Diabetes Research and Training Center. Dr. White returned to Washington University in 1991. He is also Co-Unit Leader of the Pediatric Patient-Oriented Research Unit (PORU) of the Department of Pediatrics and Associate Program Director (with responsibilities for the pediatric unit) of the Washington University General Clinical Research Center. He is board certified in pediatrics and pediatric endocrinology and is a Certified Diabetes Educator (CDE).

Dr. White is a member of multiple professional societies including the Professional Section of the American Diabetes Association, the American Federation for Medical Research, the Lawson Wilkins Pediatric Endocrine Society, the Society for Pediatric Research, the American Pediatric Society, the International Society for Pediatric and Adolescent Diabetes, the Endocrine Society, the International Diabetes Federation, and the Juvenile Diabetes Research Foundation.

He has had a longstanding involvement with the American Diabetes Association at the local, state, regional, and national level and has served on many boards and committees. These have included his involvement as a member of the Research Grant Review Panel, the Scientific Sessions Planning Committee, and the Camp Task Force of the American Diabetes Association (ADA) and as Program Chairman and subsequently Chairman of the Council on Diabetes in Youth of the ADA. He is a past-president of the St. Louis Chapter of the American Diabetes Association. Dr. White has also had a 20- year involvement in the organization and operation of camps for diabetic children and was the recipient of the award for Outstanding Contribution to Diabetes and Camping of the American Diabetes Association in 1998.
