Welcome to Step By Step Pediatrics!

We are a private medical office offering preventive and sick care to children from birth to adolescence and through college age. Each patient has his/her own Pediatrician for health maintenance and children with long-term medical conditions coordinate their care with one of the nurses. We emphasize preventive health care including nutrition, bike & helmet safety, car seats & seat belts, sports safety, growth & development, and vaccinations. We enjoy watching our patients grow “Step by Step” from childhood through adolescence!

Anne J. Stump, MD, FAAP and Chrissa Collings, MD, FAAP have practiced pediatric medicine together for nearly 20 years. Krista Santos, MD, FAAP joined our office more recently. All 3 Pediatricians have completed 4 years of college education, 4 years of medical school, 3 years of pediatric residency and passed specialty board exams to become Fellows of the American Academy of Pediatrics. We also participate in continuing medical education to enhance our pediatric skills.

We are each members of the American Academy of Pediatrics, the IN Chapter of the AAP, the IN State Medical Association, the Indianapolis Medical Society, and Indiana Pediatrics. We are medical staff members at Clarian Health, Methodist Hospital, Riley Children’s Hospital, St Vincents Children’s and Women’s Hospitals, and Clarian West Hospital. We have pediatric coverage for our patients at local Hospitals (Clairan North, Hendricks County Hospital, and St. Francis).
