The Children’s Hospital of San Antonio Welcomes New OB-in-Chief November 02, 2015

Dr. Peter Nielsen joins The Children’s Hospital of San Antonio medical leadership team as Obstetrician-in-Chief. The appointment of Dr. Nielsen aligns with the Hospital’s goal to establish a world-class children’s hospital with a strong maternal-fetal medicine program. Dr. Nielsen was selected after an extensive, national search and chosen based on his impressive work with high-risk and complex pregnancies.

“Dr. Nielsen’s leadership in the area of maternal-fetal medicine demonstrates our commitment to our Hospital’s long legacy of welcoming babies to this community,” said Elias Neujahr, President of the Children’s Hospital of San Antonio. “The Center for Maternity and Motherhood at the Children’s Hospital will undergo an extensive transformation that will be led by Dr. Nielsen to better meet the needs of expectant moms. The Hospital will soon be adding additional physicians to the maternal-fetal medicine team.”

Dr. Nielsen also assumes the role of Vice Chair of the Department of Obstetrics and Gynecology with Baylor College of Medicine and reports to both, Neujahr and Dr. Michael Belfort, Chair of the Department of Obstetrics and Gynecology at Baylor. “We are delighted to welcome Dr. Nielsen to our Department, and are excited to work together with such an accomplished clinician and academician,” said Dr. Belfort.

Dr. Nielsen joins the Children’s Hospital of San Antonio on a part-time basis while completing his assignment as U.S. Army Commander at General Leonard Wood Army Community Hospital in Missouri. He joined the Army in 1987, completing his residency in obstetrics and gynecology at William Beaumont Army Medical Center in El Paso, Texas, in 1991. In addition, he completed a fellowship in maternal-fetal medicine at the University of Texas Medical School at Houston in 1995.

While serving in the Army, Dr. Nielsen rose to the rank of Colonel and received numerous military awards including five Army Commendation Medals, the Army Achievement Medal, three Meritorious Service Medals, and the Bronze Star Medal. In 2005 and again in 2011, Dr. Nielsen served as Deputy Commander for Clinical Services of the 86th Combat Support Hospital and supervised the clinical care of all combat casualties from Baghdad, and the area bordered by Syria, Iran, Saudi Arabia, and Kuwait. The 86th was the busiest military trauma hospital in Iraq, but had the highest rate of survival which led to the production of the HBO documentary, “Baghdad ER.”

Upon completion of his Army obligation, Dr. Nielsen will join the Children’s Hospital full time in July 2016. He is excited to return to his family’s roots in Texas. He was raised in Houston and attended Texas A&M University and the University of Texas Health Science Center – San Antonio. While in medical school, he met his wife Cheryl who was working as a nurse in the pediatric hematology/oncology unit at the former CHRISTUS Santa Rosa Children’s Hospital, which is now the Children’s Hospital of San Antonio. Two of the Nielsen’s three children attend colleges in Texas.
