Founding owner of C. Brown and Associates, Mr. Brown, possesses a wealth of knowledge and experience in financial consulting; commercial and government accounting; and government auditing experience. Mr. Brown incorporated his firm after spending 8 ½ years working with the Internal Revenue Service (IRS) as an agent where he progressed rapidly.

He left the IRS after becoming a subject matter expert in International Tax having resolved double taxation cases under U.S. Income Tax Treaties with foreign governments; analyzing issues, preparing U.S. position documents; communicating disposition to foreign competent authority; and negotiating cases. Mastering these tax complexities buoyed him to open his own firm to practice accounting; income tax preparation; financial management and advisory service; financial oversight and audits for individuals, corporations and governments.

Mr. Brown has also contributed to the financial stability of nonprofits, banks, and community groups by serving on various boards of directors. Notably, he served five years as Chairman of the Board of Directors, of Dimensions Health System, after having served as Chairman of the Finance Committee.


As Finance Chairman, Mr. Brown set yearly budgets for operation and capital improvements. As Chairman of the System, he provided direction and advice to the CEO and management on corporate-wide priorities including financial, brand, and partnering risk management.

Mr. Brown is also proud to have assisted the small business community. He was engaged to provide services to the District of Columbia Government, and Department of Public Works’ small business minority contractors. His scope included evaluating, advising, and installing financial accounting systems and payroll services to assist the contractors in the successful financial management and administration of capital improvement projects for the District. Mr. Brown currently serves as Chairman of the Board of Directors of Prince Georges County’s Revenue Authority.

As a home and business owner in Prince George’s County, Maryland, Mr. Brown is proud to serve in community-based organizations, business boards, religious ministry, and educating the youth. On a state and national level, he maintains membership in professional accounting organizations and accreditation from respected entities.

Mr. Brown has earned the distinction of completing the requirements for nationally recognized accreditation in taxation from the Council for Accountancy as an enrolled agent eligible to represent clients before the IRS.
