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.
Pediatric Services of Springfield is a modern pediatric practice with two convenient locations. We strive to provide compassionate, quality, evidence-based care of newborns, infants, children, and adolescents in a professional, respectful and friendly environment. The principles of our practice, established in the 1950's, is to continue to provide comprehensive, accessible, personalized, and proficient pediatric healthcare while maintaining high ethical standards and professionalism in all we do. It is our intent to partner with our families to promote prevention and a healthy lifestyle and support families in the challenges that they may face in raising their child.

We are committed to help make a difference in your child's overall health and well-being as we also strive to make a difference in the diverse communities we serve. We understand that choosing a pediatrician is a very important decision for you and your family. We are always happy to meet with parents prior to delivery so that you may get to know us and our office. We have a unique opportunity to provide guidance and education for families. We specialize in general pediatric healthcare and focus our practice on preventative medicine.

Who are Pediatric Nurse Practitioners (PNPs)?

Pediatric Nurse Practitioners (PNPs) are very special health care providers who are dedicated to improving children's health. PNPs have advanced education in pediatric nursing and health care and they serve children and families in an extensive range of practice settings. Working with pediatricians and other health care providers, PNPs have been enhancing the health care of children for over forty years.

PNPs are pediatric (registered) nurses with a master's degree in pediatric nursing. They meet state licensing, competency standards and continuing education requirements. Most PNPs are certified by a national certifying agency, guaranteeing expertise and competency maintenance.

What do PNPs do?

Since 1965, PNPs have provided comprehensive care to children and families by focusing on health maintenance and education, illness prevention and minor and chronic illness management. They are in demand due to consumer recognition, acceptance and satisfaction. PNPs have the knowledge and experience to work closely with community agencies.

PNPs serve as pediatric health care providers for well and ill children of all ages. Many parents choose a PNP as their child's health care provider knowing they will receive individualized quality health care. PNPs offer a variety of services including:
  • Provide health maintenance care for children (physical exams), including well child examinations
  • Perform routine developmental screenings
  • Diagnose and treat common childhood illnesses
  • Provide anticipatory guidance regarding common child health concerns
  • Provide childhood immunizations

PNPs are qualified to perform complete physical exams, take health histories, diagnose and treat common acute minor illnesses or injuries, order and interpret lab results and x-rays, manage stable chronic illness, counsel clients, provide health education and prescribe medications, according to state law.

Pediatric Services employs four PNPs to provide medical care to our patients. These providers practice with a state issued license and are supervised by the attending physician.
