Zena Delling
Founder and CEO

Zena Delling, founder and CEO of J & Z Dental Rentals and J & Z
Dental Clinical Seminars, has been in the dental field for 26
years. She has served the dental community as a Registered
Dental Assistant and an Instructor. She has a passion to help her
colleagues be the best they be can in this field. During the course
of her career she heard feedback about RDA Prep Courses that
were offered to our dental community, some positive and some
negative. So she took some time to think about how she would
like a RDA Prep Course to be taught.

Ms. Delling developed a great plan and so far 98% of her
students have passed both the RDA Written and Practical
California State Board. It is her goal to have a 100% pass rate,
so she keeps in touch with her students before and after her
seminars.

Ms. Delling is a member of the ADAA, CDA (ADHP), and the
Better Business Bureau.
