From his mid-teens Ronald Klaus was personally mentored intensely by a pastor in his home church in New York City. That began a life-long interest and study of the Bible. Later, he spent 20 years in pastoral ministry in 4 churches in 3 cities. He also taught in 2 seminaries and a Bible school. Since 2004 his main teaching venue has been in Ethiopia where he also mentors leaders. Helping people understand the riches of the Bible has always been a high priority issue for him. Ron’s experience in pastoral ministry and mentoring of other leaders has motivated him to communicate an understanding of the Bible as well as the practical applications to life today.
Before his time in ministry he practiced engineering in the US Space Program and he taught chemical engineering and computer science. He still maintains an interest in science and applied mathematics to this day.
