Biography

Dr. Tippi MacKenzie, a pediatric surgeon at UCSF Benioff Children's Hospital and its Fetal Treatment Center, has special interests in fetal surgery, advanced laparoscopy, and endocrine and biliary surgery. She is a member of the Biomedical Sciences Program and Institute for Regeneration Medicine, with a research focus on stem cell transplantation in utero to treat genetic disease.

MacKenzie earned a medical degree at Stanford University and completed a general surgery residency at Brigham and Women's Hospital in Boston. She completed a pediatric surgery fellowship at the Children's Hospital of Philadelphia, where she held a clinical appointment in general, thoracic and fetal surgery.
