The practice was started by Dr. John
Wilcox in the late 1940's and Dr. Richard Mabie joined him in 1961. Dr.
Wilcox retired in the mid-1970's. Dr. Mabie retired in 2000 after 40
years of service to children in the Pomona Valley. Dr. Frederick A. Lauppe
joined the practice in 1973 and retired in 2010 after years of service to many
children. Dr. Bette-Lee Jablow was part of the practice from 1976 to 1993 before she and
her husband relocated to Virginia. Dr. Jablow is now back in the Pomona area
and practicing pediatrics with Kaiser.
Pomona Pediatrics has a long affiliation
with Pomona Valley Hospital Medical Center and maintains that association because of the high
quality of the facility's inpatient pediatric care supported by inpatient
pediatric specialists and its excellent neonatology unit staffed by specialists
in neonatal care.
Over the years, our practice has grown and
currently includes seven pediatricians.
