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 at varying levels of financial expertise.


Accounting & Nonprofits

Our experienced team of professionals understands the unique and increasingly complex accounting requirements facing nonprofits today.

We build lasting client relationships by providing auditing and accounting services that are relevant, innovative and timely. We value professionalism, excellence and integrity in everything we do.


Sustainable Accounting

We are proud to be one of the few Green Certified CPA firms under the California Green Business Program.

Since opening our doors in 2011, we have adopted various cutting edge technologies to enhance our services and reduce our carbon footprint.

  • 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.
