Dr. Baum

Frank R. Baum, MD 

obtained his undergraduate degree from Northwestern University in 1977 with departmental honors in Biological Science and his MD from the Chicago Medical School in 1981. He completed his pediatric residency at the Children's Hospital of Los Angeles in 1984 and was the recipient of the Della M. Mudd Award for the effective application of scientific knowledge, perceptiveness in the care of children and distinguished qualities of character.

From 1984 to 1985 Dr. Baum was a pediatric emergency room doctor at Children's Hospital of Los Angeles prior to moving to Maui. Dr. Baum wanted to be a pediatrician since he was 8 years old and feels that he has been living the dream ever since. His goal in practicing pediatrics has always been to make an impact on the health care of children in a small community.

When Dr. Baum is not in the office he can be found teaching Bricks 4 Kidz Maui (https://www.bricks4kidz.com/hawaii-maui/ )STEM enrichment classes in many of Maui's elementary schools.
