  • Optional Personal Statement: I specialize in hip disorders from infancy to adulthood with specific attention to hip dysplasia, femoroacetabular impingement (FAI), and the sequelae of childhood hip disease. I utilize a combination of both arthroscopic and open hip preservation procedures to address the unique problems for each patient, including periacetabular osteotomy (PAO), hip arthroscopy, surgical hip dislocations, and pelvic and femoral osteotomies. My goal is to help patients to develop healthy hips and to prevent the development of hip osteoarthritis.
