Harry, a medical doctor, and Echo, a physician assistant, are founders and executive directors of The Luke Commission, registered as a non-government organization in the Kingdom of Eswatini and a non-profit charity in the United States.

While visiting Eswatini in 2004, the VanderWals saw the devastation of HIV/AIDS throughout rural Eswatini. In 2005, the couple founded The Luke Commission, named after the doctor who authored the Gospel of Luke in the Bible.

The VanderWals and their six children call Eswatini their full-time home.
