Founder & CEO

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.


Could not have done it without her - Sabine helped me study for the Audit section of the CPA exam. I had taken it twice and failed by several points both times. I started becoming stressed because I had begun working at my firm and no longer had the free time I had while going to school to study for the exam. Sabine had a lot of experience with people in my predicament and helped me develop a plan to study the material in an effective and efficient manner. She's excellent at staying on top of her students, so I had no trouble keeping pace with my study schedule. She also helped me calm me down when I became more nervous about my exam. Thanks to Sabine, I got through all the material well before my exam date, and I passed! Overall, Sabine is an excellent tutor, and I'm so happy to finally be finished with the CPA. Thanks Sabine!       — Stephen

Great teacher  Sabine knows the material inside and out and can break each concept down to the common person. The best audit tutor out there. She really knows the concepts. I would recommend her for anyone.      — Jamel

Great Tutor  - I used Sabine for the Audit part of the CPA. Without Sabine's guidance I don't think I would have passed the part on my first try. She was great with assisting me in developing an approach for the exam. We drew out a schedule together, executed that schedule, and I'm proud to say the hard work paid off. Thanks Sabine!     — Brad
