Pediatric Surgery


Katrina Weaver, MD, joined the Logan Health medical staff in October, 2023 as a pediatric surgeon. She is specialized in all aspects of pediatric surgery including minimally invasive surgery (laparoscopy and thoracoscopy), robotic surgeries, pediatric surgical oncology, pediatric colorectal surgery, and surgery on premature babies and newborns with congenital defects. Because of her previous surgical critical care experience, Dr. Weaver has a special interest in treating pediatric burns and trauma. She also has training and experience in adolescent weight loss surgery.

After earning her medical degree from the University of Utah School of Medicine, Dr. Weaver completed her general surgery residency at USA Health, University of South Alabama. She followed this training by completing a surgical critical care fellowship and a pediatric surgery fellowship at Children’s Mercy Hospital in Kansas City, Missouri. In addition to her extensive medical experience, Dr. Weaver has also held multiple faculty positions. From July of 2017 to January of 2018, she served as Assistant Professor in the Division of Trauma, Critical Care and Burns at USA Health, University of South Alabama. From January of 2020 to August of 2023, she served as Assistant Professor of Surgery and Pediatrics at the University of South Alabama Children’s & Women’s Hospital, while fulfilling the roles of Director of Pediatric Trauma and Burns as well as Co-Director of the USA Health Adolescent Bariatric & Metabolic Surgery Center. Dr. Weaver has also been recognized in Mobile Bay’s 2020 Class of 40 under 40 and was inducted into the Alpha Omega Alpha Honor Medical Society in 2017.

Originally from Riverton, Utah, Dr. Weaver and her family are excited to get back to the snow and enjoy all of the winter activities the Flathead Valley can offer. She, her husband and her twin boys have their own animal farm with horses, miniature donkeys, and longhorn cattle. When they are not tending the farm, her family looks forward to trail riding and getting involved in the local FFA and 4H Clubs. Dr. Weaver and her husband also operate a nonprofit called “Operation Every Child” that collects expired or unused hospital supplies and equipment from many different locations and ships them to third world hospitals. Once there, families in need receive these items so they can afford surgeries for their children. In addition to this, Dr. Weaver and her husband, a trained OR nurse, also routinely participate in medical missions, usually to Africa, through the Medical Mission Foundation based out of Kansas City, Missouri.
