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 Board-Certified Pediatrician for health maintenance and children with long-term medical conditions. We emphasize preventive healthcare and vaccinations. We enjoy watching our patients grow up!

We are each members of the American Academy of Pediatrics, the Indiana Chapter of the AAP, the Indiana State Medical Association, the Indianapolis Medical Society, and Indiana Pediatrics. We are medical staff members at Riley Children's Hospital, Peyton Manning Children's Hospital, IU West, and IU North. We have pediatric coverage for our patients at other local hospitals.


Biographies

Anne J. Stump

The oldest of 5 kids, I borrowed my brother's doctor's kit and proclaimed, "I'll be the doctor, you be the patient!" 

I graduated from Indiana University and Medical School, Pediatric Residency, and passed the American Academy of Pediatrics Board exam.

I am blessed to have one husband, one son, one daughter-in-law, one adorable grandson, and three kitties. In addition to loving all my patients, I enjoy Butler basketball, Disney, and sleeping in on my day off! 


Chrissa L. Collings
I was raised in Hendricks County and have continued to live in the same area for most of my life. I attended Danville Schools, Miami University, IU School of Medicine, then Vanderbilt University Hospital for my Pediatric Specialty Training.

My husband and I have two sons and now three grandchildren that we love to entertain, go to sporting events, and celebrate life with.

Practicing pediatrics has been a fulfilling joy to me. To care for kids and watch them grow in health and security is my goal. I also enjoy travel, swimming, reading, scrapbooking, and continued learning. I volunteer at a clinic in Avon, teach Bible studies, and serve on mission trips frequently. 

Krista I. Santos

I grew up in Crawfordsville, Indiana, and attended Indiana University for both college and medical school. I completed my residency in pediatrics at Ohio State before coming home to Indiana to join Doctors Stump and Collings at Step By Step.

In my free time, I can often be found reading, walking my poorly behaved dog, or meeting friends to eat or exercise (or both!). I am happiest when I am spending time talking and laughing with my husband and daughters. As my children grow up, I continue to be amazed by them every day. I feel very fortunate to also be able to share in my patients' stories and achievements as they learn and grow.
