Dr. Tis earned his medical degree from the Georgetown University School of Medicine. He completed an orthopaedic surgery residency at Walter Reed Army Medical Center, a research fellowship at Johns Hopkins and a pediatric orthopaedics surgery fellowship at UCSD Rady Children's Hospital.

Prior to joining the Johns Hopkins faculty, Dr. Tis served for four years as the Director of Pediatric Orthopaedics at Walter Reed Army Medical Center.

While in the military, he developed an orthopaedic sports medicine practice and became an expert in arthroscopically treating orthopaedic injuries and disorders. He also treated complex pediatric deformities.

Experienced in treating high-energy war wounds and limb defects, Dr. Tis served as the Chief of Orthopaedics at Ibn Sina Hospital (“Baghdad ER”) during Operation Iraqi Freedom. In 2011, he returned to Afghanistan and served for six months.
