Among the Top 5% of St. Louis Pediatricians

Drs. Arter, Eaton, Finn and Wurzel have all been recognized as being “Best Doctors” in America, an honor achieved by only 5% of St Louis Pediatricians. We share the same diagnostic and treatment philosophy and actively review the newest scientific findings in pediatrics. We also are proud to be instructors at St. Louis Children’s Hospital and Washington University School of Medicine.
