About Dr. Berchelmann

Dr. Berchelmann is a pediatrician, wife and a mother of seven children. She sees patients from birth through young adulthood. Her practice includes all general pediatric and adolescent medical needs, as well as pediatric mental health. She is commonly consulted by families desiring a faith-based approach to depression, anxiety, obsessive-compulsive disorder, ADHD, ADD, and autistic spectrum disorder. She speaks nationally on vaccines derived from aborted fetal tissue, also known as human diploid cell line vaccines.

Dr. Berchelmann is board certified in Pediatrics.

After graduating from Amherst college in 1998, she completed a fellowship in medical ethics at Weston Jesuit School of Theology. Kathleen graduated from the University of Connecticut School of Medicine in 2003, and completed her internship and residency in pediatrics at Washington University in St. Louis and St. Louis Children’s Hospital. She stayed on as clinical faculty at Washington University School of Medicine for another ten years. She also served as Spokesperson for St. Louis Children’s Hospital and learned health marketing through the media. In 2016 she accepted a faculty position at The University of Missouri School of Medicine with a clinical appointment in Pediatric Emergency Medicine at Mercy Hospital in St. Louis.

In 2018, Dr. Berchelmann founded MyCatholicDoctor, using telehealth to bridge the geographic distance between the patients and families that want Catholic healthcare and the providers that desire to practice their healing arts with the full voice of their faith. She also holds a part-time position as a pediatric hospitalist at Stamford Hospital in Stamford, Connecticut, an affiliate of Columbia University School of Medicine.
