My name is Greg Vollmar and I serve as President on the Deaf Jewish Believers Board.
I hail from southern California where I grew up in a Deaf missionary family, well-cultivated in four Deaf generations with multicultural influences.
The Lord called me to work with the Bible translator’s organization after spending many years in the field of Deaf education, teaching American Sign Language (ASL) and Deaf studies.
I have four grown children. As a current Texan, I enjoy hiking, backpacking, and camping.
