This Rabbi has also asked for anonymity and we will honor his request.  But here is some information about him.

He is one of the world’s foremost authorities on missionaries and cults.  He was educated at Northwestern University and Yeshiva University and has been involved in Jewish education and outreach work since 1975.

He has specialized in this work for going on 50 years. 

He has lectured extensively throughout the world on missionaries, cults, and issues of Jewish continuity and spirituality. His entertaining, inspiring and informative lectures have been enthusiastically received by all denominations of Judaism.

As a highly respected authority on Jewish continuity, he has acted as a consultant to many Jewish communities worldwide in developing responses to missionary and cult activity and advising on issues of Jewish survival.

He has developed and taught numerous courses on Jewish-Christian polemics and has produced a highly acclaimed counter-missionary audio series. 

He has authored many educational booklets for both Jews and non-Jews.

In addition, he has appeared internationally on many radio and television programs to discuss his vital work fighting the missionary problem and assimilation.

Additionally, he has had extensive experience working with and helping numerous affected families and in counselling hundreds of Jews who have embraced Christianity and other faiths. He is personally responsible for rescuing countless Jewish souls and helping to bring them back from the clutches of missionaries to the Jewish fold and reuniting them with their families.

He is an excellent resource for providing non-Jews with answers, practical advice and counseling for those who are leaving or have left the Christian or Messianic movement and those dealing with family issues for leaving a previous religious system.
