The Founder & CEO


Sabine Charles

Continuous learning is the key to continuous growth and success.”

Ms. Sabine Charles has been advising senior executives in Internal Controls, Business Risk, Fraud Investigations, and Operational Auditing for over 15 years. 

Sabine Charles has taken the Certified Internal Auditor (CIA) exam several times and is familiar with the stress and pressure that accompany preparing for certification exams. By attending many review classes, self-help seminars, and learning several alternative learning techniques she was able to develop anxiety management techniques that helped her not only pass the CIA exam but also achieve eight other certifications in the fields of information technology, auditing, and risk management.

Her preparation for her own exams and experience working for several tutoring firms and teaching undergraduate and graduate classes further honed her skills in accounting, auditing, and information technology. Sabine created TAPA Institute because she recognized that she had accumulated the necessary tools to help individuals pass accounting related exams – specifically the CIA and CPA exams – and become accounting and audit professionals through TAPA's virtual apprenticeships.
