What Makes Us Different

At Cook & Company, we focus exclusively on working with nonprofit organizations. We provide friendly, exceptional service at reasonable rates.

We understand that many small and medium-sized nonprofit organizations do not always have professional accountants on staff, and we take pride in our ability to work effectively with managers, staff and board members with varying levels of financial expertise. In addition, we have a penchant for explaining technical accounting and tax concepts in “plain English”. We also make useful suggestions throughout our engagements, thereby helping clients enhance the effectiveness and/or efficiency of their activities.

We follow a rigorous system of quality control standards, which is required by membership in the American Institute of Certified Public Accountants and subject to a periodic peer review.  We also stay current on the latest accounting, audit, and tax pronouncements through extensive continuing education activities. This allows us to provide clients with the most current and relevant expertise.

Sustainable Accounting & Use of Technology

We are proud to be one of the few Green Certified CPA firms under the California Green Business Program.  Since opening our doors a few years ago, we have adopted various cutting edge technologies to enhance our services and reduce our carbon footprint. We have migrated from traditional paper-based auditing to a computer-based audit management system. To safeguard our client data, our file server is hosted within an SSAE16-compliant data center in California. In addition, we use the Internet and email to exchange correspondence with clients and vendors whenever possible. We have a secure online portal for our clients and encourage them to submit materials to us electronically in order to conserve paper and reduce greenhouse gasses associated with traditional shipping and mailing methods. For us, being green is socially responsible and makes good business sense, too. The money we save by following environmentally friendly practices allows us to offer our nonprofit clients exceptional service at reasonable rates.

  • Sunburst Projects is a small non-profit agency that has worked with Douglas Cook for the past ten years. As our independent accountant, Douglas and his staff have provided Sunburst with professional, knowledgeable, friendly and reliable service through some very complicated and trying times for the agency. He and his staff are responsible for Sunburst’s annual audit and 990 returns. We are delighted with the quality of Cook & Company’s service, integrity, competence and reliability. They are extremely knowledgeable about nonprofits and fiscal management and we would highly recommend their services.

  • The San Francisco Bicycle Coalition has had quite a positive experience working with Cook & Company for our audits and 990s. Douglas Cook and his staff are straightforward and meticulous. We would recommend Cook & Company to other nonprofit organizations.

  • Our finance team highly values the working relationship we have with Douglas and his staff. They are incredibly well organized, quick to respond to our various (and sometimes many) inquiries and attentive to our particular concerns. Douglas knows our organization well and it shows in the thoroughness of his questions and his ultimate work product. He doesn’t just understand nonprofit accounting and tax issues; he is also very skilled at explaining them. Our board’s audit committee – which can be a “tough crowd” – has consistently found his presentations to be both rigorous and helpful. On top of all of this, Douglas and his team are just wonderfully pleasant to work with, which I can’t say has been a common experience when working with audit and tax professionals!

  • Cook & Company has been our auditor for the past two years and they operate in a very thorough and professional manner. They work to meet our very tight year-end schedule and perform a comprehensive audit within the required time frame. It is important to us that we have an auditor that works exclusively with nonprofits and one who has a deep understanding of the complex nature of our organization. Cook & Company has proven to be the perfect choice.
