About Pediatric Services of Springfield
The History Of Our Practice
This practice began in the 1950s when it was known as Dr. Ellsworth A. Twible, Inc. Dr. Twible was a wonderful pediatrician
who practiced with caring, understanding, and a genuine love for children and their families while bringing knowledge and new pediatric ideas and insights into this area.
Dr. Leif Nordstrom joined Dr. Twible in 1981, and the practice name changed to Pediatric Services of Springfield
in 1984. Since then, our physicians have cared for four generations of families with our first patients now bringing their children, grandchildren, and great-grandchildren to our practice.
