Through coursework at the Messianic Jewish Theological Institute (MJTI), Ken began pursuing Smikhah (rabbinical ordination) from the Union of Messianic Jewish Congregations (UMJC) and the Messianic Jewish Rabbinical Council (MJRC) in the Summer of 2014. In the meantime, he joined the Board of Congregation Zera Avraham and was officially named Assistant Congregational Leader in 2018.
Ken and his wife, Eva, are the proud parents of six children, ages 4 years through 25 years, two more children for whom they have been guardians, and one more sweet girl who they fostered for 2 1/2 years. They are also blessed to now have their first grandchild. Ken and his family, enjoy the charm and challenges of their 145-year-old home in small-town Milan. Ken grew up attending services at Temple Israel, a Reform Jewish congregation in Metro Detroit and was extremely active as a Jewish youth and teen spending summers at Camp Tamarack and serving as President and Treasurer of his chapter, Rose A.Z.A., of the B'nai Brith Youth Organization (BBYO). These early Jewish cultural experiences imbued Ken with a heart for issues of social and environmental justice.
In his late thirties, Ken came to faith in Messiah Yeshua and began a journey of following our great and eternal Kohen Gadol. That journey has led him to become more Torah-observant than he ever imagined.
Ken has a Bachelor of Arts in Political Science degree from the University of Michigan, Ann Arbor, and a Master of Science in Information Systems from Lawrence Technological University. After working for Hewlett Packard, Compuware, and Ford Motor Company, he settled in at a real estate multiple listing service (MLS) where he has spent the last 24 years and is currently serving as their Chief Technology Officer.
Ken is available to lead Passover seders and to speak to synagogues, churches, small groups and chavurot with the goal of building bridges, growing interfaith relationships, and helping others to understand the continuing role of the Jewish people and their eternal covenant with HaShem and His Messiah Yeshua.
