Cotton & Company has 11 partners with diverse backgrounds, interests, and talents. Several of the nine partners joined Cotton & Company at the entry-level right after college graduation and worked their way up through the firm. All partners have extensive technical experience in one or more specialized areas, but also possess an overall understanding of Cotton & Company's diverse practice.

Professional Experience and Development

Cotton & Company partners stay ahead of the competition: they are active in professional organizations (many serve as committee officers or chairs), and they keep ahead of industry trends and practices. Continuing experience on the assignment "firing line" fosters not only a closer understanding of changing client needs but also the in-depth development of mutually supporting practice specialties among the partners.

Professional Memberships

Several Cotton & Company partners have experience working with standard setting boards either in the capacity of a board member, an expert witness, or as a member. Our partners are members of professional organizations, including AICPA, AGA, VSCPA, IAA, ISACA, and ACFE. Several partners have been board members for some of these organizations, as well.

Engagement Involvement

A key to Cotton & Company’s long-term and consistent success is partner involvement in daily engagement management. Partners are able to provide their unique, specialized perspectives to each engagement, foster continuing relationships with our clients, and enable professional growth for all personnel. We emphasize the importance of quality on all engagements, and direct partner involvement is our commitment.
