Firm Profile

We are Wendell T. Walker & Associates, P.C., a Boulder, Colorado CPA firm which offers tax services to individual clients. corporte, partnerships, trusts, and estates.  We also provide business consulting on a case by case basis.  We are the certified public accountants for many Boulder County based clients and several clients in the Denver area. Additionally, we represent individuals and business entities on a case-by-case or project-by-project basis in a wide variety of matters.

Since our formation in 1970, we have grown to be a medium sized Boulder CPA firm, meeting the needs of growing clients and an expanding clientele. Our ability to provide comprehensive accounting services includes advice and representation in the following specialized areas: professional service organizations, construction accounting,  tax and financial planning, and computer systems. We are members of the American Institute of Certified Public Accountants, Colorado Society of Certified Public Accountants, and Division for CPA Firms PCPS. We have completed nine peer reviews with unqualified opinions.

We view ourselves as problem-solvers for our clients. Our goals are to establish effective working relationships with our clients, to be knowledgeable about their business and financial affairs, and to accomplish financial planning in light of their circumstances and objectives. We emphasize the importance of excellent record keeping and transaction planning in both business and personal transactions.

Although clients may generally establish a primary relationship with one or two CPAs in our firm, the resources of the entire firm are available to address new and varying needs of our clients. When a specific project demands it, the accountants work together as a team. For example, in the audit or review of a client, frequently the accountant in charge of the audit or review will call upon a tax specialist to assist in planning and reviewing the client's overall future long-term plans. By teaming up when the situation requires it, we efficiently combine the different expertise of accountants to provide our clients with high quality accounting services in a timely manner and at a reasonable cost.

The CPA-client relationship requires complete trust and confidence. We keep our clients' affairs confidential and are committed to meeting all our ethical responsibilities. Our clients are regularly informed of the progress on their accounting work by e mail, telephone, correspondence, memoranda and copies of the work produced, as appropriate. Clients are encouraged to discuss questions about work being done for them or the relationship with their accountants. Sound business practices help us to be cost efficient, punctual and productive in providing accounting services. We employ and hire the best available personnel, and use state-of-the-art technological support systems. Our staff works together to deliver prompt, economical accounting services to our clients. Our accountants participate in an ambitious continuing accounting education program through internal, local and national educational programs to remain at the forefront of accounting and tax developments affecting our clients. We provide and maintain an up-to-date tax library which we supplement with various specialized materials we purchase directly. We have a computerized on-line tax library which gives us computerized access to all tax updates immediately.

We supply our clients with complimentary summaries and comments regarding major changes. We also prepare, on an as needed basis, special newsletters which discuss topical tax law changes and highlight current tax developments for our clients.


Our fees are based upon the nature of the work, the time required and the responsibility and ability of the accountant involved. Most fees are determined on an hourly basis, as adjusted for factors such as expertise and value of the relevant work being performed.

Our hourly billing rates reflect our estimate of the value of the experience and skill of the individuals performing the work. Hourly rates do not include such items as travel expenses incurred on behalf of a client, computer service charges, postage and other miscellaneous charges in excess of ordinary and necessary office expenses. These expenses are itemized and billed monthly. We routinely discuss the matter of fees and expenses at a client's first meeting in order to ensure a clear understanding regarding a client's entire financial obligation and our obligation for services. At that time, each client is provided and requested to sign an engagement letter setting forth the understanding regarding fees, requirements and responsibilities of the client, and requirements and responsibilities of the accountant.
