In 1992, he became a Fulbright Scholar at Aga Khan University Medical School in Karachi, Pakistan, where he set up postgraduate training programs for the university.

Dr. Johnson holds multiple certifications in advanced life support for both adults and pediatric patients. He has spoken at national and international conferences in the United States, Canada and Pakistan and is a published author of clinical literature.

His desire to provide the best care for his patients was the motive behind the founding of EMDTransfer in 2007, a cloud-based service that provides distant specialists with critical patients medical images. This speeds up the decision-making process as to whether a patient needs to be transferred to a hospital that provides a higher level of care or remain at the original facility. Unnecessary patient transfers add more layers of cost to the healthcare system, deprive community hospitals of needed revenue, and are an inconvenient burden to patients and their families. In late 2011, GlobalMed purchased EMDTransfer and added Dr. Johnson to its medical Advisory Board.
