Chapter Beginnings
It’s hard to imagine, but it has been 70 years since the Oklahoma City Chapter of the Institute of Internal Auditors, Inc. was established. On September 1, 1949 an initial group of 18 internal audit professionals founded the local chapter, passed the by-laws and elected the original officers and one governor. They also determined that chapter meetings would be held on the first Thursday evening of each month.
The original 1949 members were:- W. Leo Austin
- J. R. Larimore
- Paul C. Barnhart
- A. W. Levan
- Orbin J. Casey
- S. A. McAdams
- Marlin S. Crossley
- S. W. McNeely
- Vernon Dillingham
- S. B. Robinson
- W. K. Garrett
- Richard N. Tuggle
- Dub B. Geizentanner
- Jesse P. White
- J. N. Keating
- Horace F. Windham
- Rolland E. Kerns
- Roy Winters
During the last 70 years, we’ve grown to an all-time high of 355 members, representing 102 organizations. We provide a wide range of opportunities for professional development and communication, such as Chapter sponsored lunch meetings and seminars, monthly newsletters, and a directory of Chapter members and events. We are committed to adding value to our members, member organizations, Chief Audit Executives (CAEs) and profession. As such, we are currently attempting to expand the scope of our outreach and communication efforts (e.g., website development, CAE Roundtables, etc.). Please bear with us during these ongoing efforts.
Our principal mission is to:- Provide continuing professional education (CPE) activities and standards for the practice of internal auditing and
- Research, disseminate and promote knowledge and information concerning internal auditing, including internal control and related subjects.
The Chapter supports this mission by:
Offering 9 monthly one-hour CPE luncheon each month (September through May).
Offering 2 seminars (Fall and Spring ) worth 16 to 24 CPE hours each. -
