About Our Firm


Colby & Powell, PLC is located in Gilbert, Arizona under the ownership of Scott T. Powell, James S. Usevitch, and Scott J. Graff, with Mr. Powell as the managing partner.

Colby & Powell was established in 1982 and since that time has continued to provide its clients with audits, exceeding the standards set by all funding sources and regulatory agencies. Colby & Powell, PLC has helped audit clients improve their accounting systems and internal controls through helpful suggestions made through observations during the course of the audit.

Our professional staff includes three partners, one audit manager, two senior auditors, three staff auditors, three para-professional accountants, and one secretary-receptionist. All audit staff members have accounting degrees, and all key staff members are certified public accountants.

Commitment to Quality

The single most important factor in our firm’s success over the past 30 years has been our commitment to high standards of quality and professionalism. Providing quality service to our clients is our primary objective, and we have developed review procedures and communications that ensure the highest standards of performance.

Colby & Powell, PLC’s goal as an audit firm is not only to provide our audit clients with an audit that will be accepted by all funding sources and regulatory agencies, but to help our clients improve their accounting system and internal control by offering suggestions during the course of the audit and reporting these suggestions to management and the governing body.

Colby & Powell has undergone its fifth tri-annual peer review required by the American Institute of Certified Public Accountants. The peer review program is dedicated to ensuring that participating firms have quality control systems in place over their accounting and auditing practices. This program includes a review of our government and nonprofit clients. We are pleased to have excelled in this review and all of our previous reviews.c
