Who We Are

Meet the CEO and Founder

Zena Delling, founder and CEO of J & Z Dental Rentals and J & Z Dental Clinical Seminars, has been in the dental field for 32 years. She has served the dental community as a Registered Dental Assistant and an Instructor.  She has a passion to help her colleagues be as successful as possible. During the course of her career she heard feedback about RDA Prep Courses that were offered to our dental community, which entailed both positive and negative commentary.  It was at that point she identified the need for an RDA program that offered quality education to the RDA community in a positive setting.  In 2006 J and Z was developed and her students have had a 98 % success rate with both the RDA written and Practical California exams.  It is her goal to have a 100% pass rate, and to keep in touch with her students before and after her seminars.  She graduated from San Diego Mesa College Dental Assisting Program in 1984. Ms. Delling is a member of the ADAA, CDA,DAERS, CADAT, and the Better Business Bureau.  


Zena is happily married with 3 beautiful children. Loves God. Loves to camp, fish, garden, race cars at K-1, travel & spend time with family and friends.
