Board of Directors

Arnold S. Leonard, M.D., Ph.D., Chairman






Dr. Leonard attended the University of Minnesota, graduating from the Medical School in 1955 and receiving his Ph.D. in 1963. While in medical school, he worked in the operating room during the first open-heart surgery. After completing residency in General Surgery, he was specifically chosen by Dr. Wangensteen to seek specialty training in Pediatric Surgery.

He conducted the first thorascopic surgical procedure at the University of Minnesota, breaking into the minimally invasive surgery arena and leading the way to the development of advanced laparoscopic and thoracoscopic techniques. Dr. Leonard has developed several medical devices including a novel long-term central venous access catheter that is the most popular long term central catheter used today in the United States for the delivery of chemotherapeutic agents in cancer patients. He has contributed to the understanding of metastatic Wilm’s tumor and its role of neoadjuvant chemotherapy; a move by the Children’s Cancer Research Committee that has literally saved thousands of lives throughout the world. He also developed a method to expose the spine from an anterior approach; a technique that has revolutionized the treatment of scoliosis. Dr. Leonard also developed a novel method to correct chest deformities; Pectus Excavatum and Pectus Carinatum. To date, he has performed over 1500 of such repairs and is considered to be one of the world’s experts in the treatment of such deformities. Surgical protocols that he developed concerning the treatment of children with cystic fibrosis are now employed nationwide.

He has given over 60 national and international talks and authored over 260 peer-reviewed publications. Dr. Leonard’s research laboratory has received two American College of Surgeons awards and the Watson Award from the University of Minnesota for innovative approaches in boosting the immune system. He holds an Endowed Chair in Pediatric Surgery in the Department of Surgery at the University of Minnesota and continues to research Genetic Engineering.
