Vickie A. Vaclavik, Ph. D., R.D., Retired. 

Dr. Vickie Vaclavik taught for over 25 years at the college level in Dallas, Texas. Included among her students were nutrition students at the Dallas County Community College District; Food Science, and Food Service Management students at The University of Texas Southwestern Medical Center at Dallas, Nutrition Department Graduate School; and culinary students at the International Culinary School at the Art Institute of Dallas.

Personally, she really likes passing on what she knows and enjoys.

Two of her three sons are married with children of their own!
