I have 31 years of experience in the field of economic damages with specific knowledge of lost profits, reasonable royalties, fair market value, diminution of value, personal injury damages, causation and professional standards. I have published on such topics as the appropriate business valuation discount for lack of marketability, the appropriate view of levels of business value, and explanation and reconciliation of the various types of business valuation empirical studies. I have testified 70 times on topics such as damages, causation, money tracing, professional standards, accounting misrepresentation and business valuation.
