A father himself, Dr. Sandberg understands deeply how every one of his patients is an entire world, and his devotion to his patients and his work shines through on every page. We follow him as he finds his way to neurosurgery as a young doctor through to his most heartbreaking cases and greatest triumphs. We also travel with him to underserved countries, where lifesaving surgeries that are common here are almost nonexistent, and Dr. Sandberg shares the stories of the dedicated doctors and surgeons trying to enact change.
