She received her Bachelor of Science degree in Biology from the University of Texas at Arlington and then went to Texas A&M Baylor College of Dentistry in Dallas where she received her Doctor of Dental Surgery degree. 

Dr. Padua enjoys dentistry because it is a field that allows her to bring together her love for science and art.
