Porter, Muirhead, Cornia & Howard was established on January 1, 1991 by the merger of Porter, Muirhead & Co., CPA's, Cornia, Howard and Company and James B. Dodson formerly of Harris, Huber and Company.  The predecessor firms were established to deliver services to clients at the highest level of competence. Prior to merging, each firm had grown to become medium sized local practices. The merging of these three practices resulted in the development of the largest local firm in the state of Wyoming. While growth alone is no measure of competence, we believe it is an indication of client satisfaction with the quality of our services.

The firm and/or its staff are members of the American Institute of Certified Public Accountants, Wyoming Society of CPA's, Casper Chapter of CPA's, Government Finance Officers' Association and the Wyoming Association of Municipalities. The firm is also a member of the Private Companies Practice Division of the American Institute of Certified Public Accountants. In addition, we strive to improve our community through involvement in various civic organizations and to upgrade our profession by becoming involved in the community and in professional organizations.
