At a time when many people are at the prime of their career, Deborah Horenstein is just beginning hers. After raising three children, she will become a doctor at this stage of life – mainly because of her youngest daughter, Ariella, who died at the age of 8 1/2 following a bone marrow transplant in 2007.

according to Rutgers News, Horenstein said, “I chose to embark on this path to become a pediatrician because I felt I could offer a unique perspective to patients and their families, having been on the receiving end of medical care,” said Horenstein, who graduates from Rutgers’ New Jersey Medical School this month. “Throughout Ariella’s illness, I saw what truly exceptional physicians can do for a family with an ill child. I strive to be that kind of physician myself.”

Medicine was not on Horenstein’s early trajectory. She was an economics major at Barnard College and worked in finance during her early 20s. After having children, she stayed at home with two young daughters, Shoshanna, now 21, and Talya, 19.

But then Ariella was born. She had complicated medical problems from the start – low muscle tone and immune problems and, later, Crohn’s disease and epilepsy.  By the time she was 4, Ariella had seen more than 50 doctors in 12 areas of specialty.

“She had an immune dysfunction and a constellation of symptoms that doctors had never seen,” Horenstein said.  “Because of the intricacies of her case, I became an integral part of the medical team. The doctors relied heavily upon my input as I knew Ariella so well.”

“Ariella had an amazing spirit – happy, laughing, singing – despite enormous pain,” said her mother.

Over the next year and a half, Ariella struggled with complications from the transplant.

Initially, there was hope, but ultimately graft versus host disease and severe infections overcame her and Ariella died in November 2007.

Horenstein’s grief not only encompassed the loss of her beloved child, it also included the loss of her constant occupation.

A year after Ariella’s death, Horenstein enrolled in Columbia University’s post-baccalaureate premedical program, and four years later was accepted as a first-year student at New Jersey Medical School.

“I decided to go to NJMS, in part, because of its emphasis on humanism,” Horenstein said. “The school places a great deal of importance on compassion, respect and empathy, values to which I am deeply committed.”

She will stay at NJMS for pediatric residency and hopes to do a pediatric neurology fellowship beyond that.
