Daniah Greenberg

Founder & CEO

Daniah, a wayward catholic with Jewish ancestry, came to faith after a single visit to a Baptist Church while in college. She graduated with a degree in Communications and married a “nice Jewish boy” named Mark Greenberg in 1989.

After 14 years in congregational ministry, the need for a “Messianic Family Bible” for the next generation of Jewish believers was made incredibly apparent. She took up the charge and effectively gathered leaders from throughout the national Messianic Jewish and Christian community to birth a brand new translation of the Bible: the Tree of Life Version (TLV).

She now leads a diverse team of 70 professionals representing Messianic ministries nationwide and affiliates in Israel to maintain the text. She is also the spokesperson and chief fundraiser for the Tree of Life Bible Society, whose mission is to see God’s Kingdom grow through the unique Hebraic perspective God has given them. Daniah is a spark plug for community activism and energizes catalytic change wherever she goes. She and her husband, Rabbi Mark lead Congregation Shalom Rome in Rome, GA and have been married for 28 years.

Dr. Jeffrey Seif

Jeffrey L. Seif was born into a German-Jewish family on November 9th 1955. He was raised in a typical American Jewish household, save the fact that he was sent off to go to school in a Yeshiva—an Orthodox Jewish training school. Though raised with a “traditional” Jewish upbringing, Jeff eventually came to a saving faith in Jesus, subsequent to which he experienced a “call” into vocational ministry. Jeff went to school to prepare for the ministerial vocation, taking studies at the Moody Bible Institute, Trinity College, and then the theological Seminary at Southern Methodist University, where he took both a master’s degree and doctorate.

Seif is one of the Messianic Jewish movement's best-known personalities. He is best known to the general public through his high visibility work with the nationally-syndicated TV concern called Zola Levitt Presents, where he sat at the teaching helm and shot programs in Israel which, in turn, were broadcast in the States through a variety of major networks. Dr. Seif has held the title “University Distinguished Professor of Bible and Jewish Studies” at Kings University-Houston, and also taught in the university's Dallas and LA campuses. In addition, Professor Seif served as a Bible professor at Christ for the Nations Institute, a position he held for 26 years.

Dr. Seif is the author of many books and has done over 100 programs in/from the Middle East.

Rabbi Mark Greenberg

Chairman

Messianic Rabbi Mark Greenberg is resolute in his conviction that the Good News of Messiah Yeshua holds the resurrection power to transforms lives today. That conviction in Yeshua’s resurrection power comes from his own faith journey.

Rabbi Mark invited Yeshua to be his Savior after reading Isaiah 53. Born the son of Conservative Jewish parents in Rochester, New York, secular education was their highest goal for him. Wrongly diagnosed as dyslexic and learning disabled as a child, Mark credits God with helping him earn a degree in Electrical Engineering from Rochester Institute of Technology. He has worked in the nuclear industry for over 17 years of faithful service.

Growing up amidst severe financial distress and other challenges in his family, Mark credits God with teaching him how to build and cultivate a healthy loving family of his own. Together with his wife, Daniah, Mark is committed to passionate service to the Lord, beginning with his family. He delights to see his three beautiful children grow in their faith and reverence of Yeshua. His family loves to worship and serve God together.

Mandie Cook

Executive Administrator

Mandie Cook is the Donor Relations Manager and Post-Production Text Manager for the Tree of Life Bible Society. After a childhood of congregational ministry by association with her parents, Mandie showed a pension for music and was added to her congregation's worship team at the tender age of 14. By the time she was 17, she was a senior worship leader. After graduating high school in 2007, Mandie took time off of schooling to discover her life's true calling. 

It was in 2010 that she was given the opportunity to serve with Jews for Jesus as a Mobile Musical Evangelist with their experimental band - Blue Mosaic. After a year of touring and evangelism, she came off the road and returned to congregational ministry alongside her family. During her time on tour, God had been at work with her mother, Daniah Greenberg, bringing about the Tree of Life Version of the Holy Scriptures. Heeding the call to her family’s unique calling, Mandie joined the staff of the Tree of Life Bible Society in late 2011 and has felt a distinct calling to theology ever since. She is now working on her degree in practical theology with a Messianic Jewish concentration at the King’s University.

Lauri Pack

Administrative Assistant

Lauri Pack describes herself as “a believer, wife and mother in that order”. She delights in reaching out to others blessed by the Tree of Life Version (TLV) to support, pray for, and present opportunities to see the Kingdom of God grow through the ministry of the Tree of Life Bible Society.

Lauri was raised as a Christian, and doesn’t remember a time that she didn’t believe in the God of Abraham, Isaac, and Jacob. But her faith was tested through many years of hardship before she was set free by ADONAI. Her personal experience of God’s faithfulness then cultivated a deep desire to reach out and share His love, shalom, and joy with others.

Lauri began studying the Jewish roots of her faith with her (then) boyfriend in 2001. Together, she and her (now) husband are raising four beautiful children with Messianic Jewish beliefs and traditions. She believes, “There’s such a depth of understanding to be gained when you study the entire bible understanding that you are reading the story of the relationship between ADONAI and His chosen people and the love He shares through them for all mankind.”
