Jan Markell was saved under Jewish evangelist Hyman Appleman when she was a child. In Jan’s early ministry years she was a part of the Messianic movement, worked for pro-Israel agencies, and for Jewish evangelism ministries.

In 1982, Jan incorporated Olive Tree Ministries and the goals of the ministry can be read at “Our Purpose.” Jan has written eight major books with prominent Christian publishing houses. She has produced a dozen DVDs, some featured on Sky Angel. At one time she traveled full time across America as a speaker.

In the year 2000, Jan launched a radio branch of the ministry starting first on AM980 KKMS, Minneapolis/St. Paul. In 2004, the program was syndicated nationally and is heard internationally on the Internet. “Understanding the Times” radio has been received well as a source of news and information hard to find. “Understanding the Times” is interview and commentary-driven.
