I am a valuation economist who brings clarity to valuation disputes by ensuring valuation economic opinions are proper, relevant, understandable, and defendable. In this capacity I serve as an expert witness, arbitrator, mediator, and litigation support advisor. I have been involved in hundreds of litigated matters with claims totaling over $1-trillion, was an FBI Academy instructor on forensic investigations of appraisal fraud, a real property tax appeals commissioner for the District of Columbia, and is an author on valuation theory and methodology. Through my nation-wide and international experience of working on some of the largest and most heavily contested valuation disputes – the litigated property value diminution claims related to the Exxon Valdez oil spill is an example – to much smaller litigation, my active involvement and leadership in national and international professional matters related to the valuation profession, my management of the largest litigation support team in the US specializing in real estate valuation issues, I bring substantial experience to the cases I become involved in.
