WWL says

Garrett Rush stands out among peers in the US market for his impressive work providing financial analysis and valuation in high-value arbitral disputes.


Garrett is a founding partner of Versant Partners, a specialised dispute consulting firm. He has been appointed as an expert in US court, ICC, UNCITRAL, AAA/ICDR, and ICSID matters. He has advised an equal balance of claimant and respondent clients facing critical and time-sensitive challenges for over 20 years and across six continents.

Over the course of his career, Garrett's work has spanned industries including: telecom, mining, real estate, insurance, transportation, consumer goods, infrastructure, technology, and all aspects of energy. Clients value Garrett's methodical, transparent, and practical views on damages claims. This approach has resulted in a track record of successful quantum outcomes with multiple awards exceeding $1 billion, and other influential precedents for claimants and respondents.

Garrett's success as an expert witness comes from the intellectual rigour and focus he brings to every engagement. He is hands-on from the start to the finish of every project. Garrett’s approach to valuation analysis in the context of disputes is informed by practical valuation and financial analysis experience gained when: developing revenue enhancement strategies for private equity-backed companies, guiding investors through potential regulatory impediments to pending mergers, providing investors and corporations analyses and strategies related to special situation events, and developing business plans for early-stage projects and their intellectual property.

Garrett regularly speaks and writes about damages and valuation issues. He holds the internationally recognised designation of chartered financial analyst (CFA). He received an MBA from INSEAD (France) and a BS in economics from The College of William & Mary.
