Two pediatric gastroenterologists bring life-saving care to kids and make Renown their new home

The Renown Children’s Hospital team and our community is celebrating the addition of a new life-saving pediatric specialty to its practice serving children and families in northern Nevada.

Parents and guardians will now be able to seek professional pediatric gastroenterologist care with the addition of Drs. Juan Gregory and Kathleen Holland to Renown Medical Group.

“Recognizing the importance of diagnosing and caring for children who have conditions that affect the organs in the digestive system, including the stomach, liver and bowel, while also helping children who have issues feeding and eating, is critically important to us at Renown,” said Kristina Deeter, MD, MBA, FAAP, Chair of Pediatrics, University of Nevada Reno School of Medicine (UNR Med) and Physician-in-Chief, Renown Children’s Hospital. “Both Drs. Gregory and Holland are superb clinicians, we are excited to have them join Renown Children’s Hospital to offer pediatric gastroenterology services, including a wide range of complex and vital procedures and screenings, endoscopies and colonoscopies.”

Juan Carlos Gregory, MD, has 18 years of experience caring for children in northern Nevada. He is a clinical associate professor of pediatrics at UNR Med with a special interest in celiac disease, abdominal pain, and gastroesophageal reflux in children. Gregory earned his undergraduate degree at Texas Christian University in Fort Worth, TX before completing his medical training, including a residency in pediatrics at the University of San Diego in Pediatrics and fellowships in Pediatric Gastroenterology and Nutrition at both Children’s National Medical Center in Washington, DC, and at the National Institutes of Health, Digestive Disease Section in Bethesda, MD. He is board-certified in Pediatric Gastroenterology and speaks Spanish.

Kathleen Holland, MD, MPH brings a global health perspective to her work caring for children. A graduate of the University of Nevada Reno School of Medicine (UNR Med) with her medical doctorate and her master’s in public health with a social and behavioral health emphasis, she has donated her skills to providing international medical relief for children in Uganda and Nicaragua. Holland earned her undergraduate degree at University of Nevada Reno in Biology, Health Ecology and Healthcare Ethics before completing her medical training and residency in Pediatrics and a fellowship in Pediatric Gastroenterology at Indiana University School of Medicine in Indianapolis, IN. Her research and scientific interests include vaccination rates and family barriers among children with inflammatory bowel disease, Crohn’s and colitis, pediatric autoimmune pancreatitis, and cystic fibrosis.

Now Being Constructed: Expanded Inpatient Care at Renown Children’s Hospital

New construction of an expanded Neonatal Intensive Care Unit (NICU) with increased capacity to 49 bassinets, an expanded Pediatric Intensive Care Unit (PICU) with increased capacity to 16 private patient and family rooms, and a new Renown Children's Hospital inpatient floor with increased capacity for 38 private patient and family rooms for a total capacity of 58 pediatric beds are currently being constructed on Tahoe Tower, Level 5 of Renown Regional Medical Center. It is expected that the new units will open to patients and families in April 2023.

In the most recent US News & World Report Best Hospital rankings, Renown Regional Medical Center was named as the number one hospital in Nevada. No other hospitals in the state met their stringent standards for the 2021 rankings. Renown Health is High Performing, its highest rating possible, in eight procedures and conditions including Heart Failure, Colon Cancer Surgery and Chronic Obstructive Pulmonary Disease, Hip Replacement and Knee Replacement. A hospital's score is based on multiple data categories, including patient outcomes, safety, and volumes. Hospitals earning a High Performing rating were significantly better than the national average.

Gregory and Holland are pleased to see new patients at their location at the Renown Children’s Subspecialty Clinic inside Renown Regional Medical Center at 75 Pringle Way, Suite 505, Reno, Nev.
