Who we Are

Brian Forensics LLP is a specialist forensic accounting and investigations firm providing evidence-led solutions for fraud, financial misconduct, and dispute matters. We combine forensic analytics, strong documentation discipline, and litigation-ready reporting to help boards, management teams, donors, and regulators make confident decisions in high-risk situations. With seven integrated practice areas, including fraud examination, lost profits and damages calculation, litigated business valuation, forensic technology, audit and assurance, tax advisory, and accounting malpractice claims investigation, we serve businesses and organizations across numerous sectors, including law firms and legal entities, insurance companies, banks, accounting firms, government agencies, and corporate stakeholders.

The firm was founded by Brian Onyango, CPA, CFE, who has over ten years’ experience in accounting, investigations, and dispute support. Formerly known as Brian Forensics, the firm was rebranded to Brian Forensics LLP in 2023. Our core aim is to deliver independent and defensible work that establishes facts from source records, quantifies financial impact, identifies control weaknesses, and provides practical recommendations to strengthen governance and prevent recurrence.

Brian Forensics utilizes technology to effectuate well-organized, solid cases from start to finish. The firm utilizes custom evidence tracking system and storage facility to establish and maintain a chain of custody over evidence. Most accounting firms offer the “traditional” menu of services. While experienced accountants well versed in accounting and/or taxes can address many accounting and tax-related matters, when issues arise either very specific in nature or outside the traditional accounting services, specialists with the appropriate background and experience should be considered to best address the matter.

Core forensic service areas include: litigated business valuation; forensic technology and data analytics; lost profits and damages assessment; and accounting malpractice and professional standards reviews
