Issues I Analyze and Opine On

My expert-witness work helps counsel analyze the business, insurance, client-relationship, causation,
and damages issues underlying complex disputes. Depending on the matter, my analysis may address:

Non-Compete / Non-Solicitation Disputes:  What does the client history indicate about causation, expected retention, and resulting economic impact?

Breach of Fiduciary Duty: What client, relationship, and business consequences followed from the alleged conduct?

Defamation & Reputational Harm: Is there evidence connecting the alleged conduct to client loss or other measurable business damage?

Business Interruption / Loss of Value: What would the business reasonably have produced but for the alleged event?

Bad Faith & Insurance Practices: What industry customs, practices, and standards are relevant to the challenged conduct?

Client Retention & Causation: Would the clients have remained but for the alleged conduct? What does the historical retention and relationship evidence indicate?

Tortious Interference / Client Solicitation: What role did the alleged conduct play in client departures, and what would likely have occurred absent that conduct?

Lost Revenue & Business Value: What revenue, profit, or enterprise value was reasonably likely to continue absent the alleged event?

Insurance Industry Customs & Practices: Did the conduct at issue align with generally accepted insurance-industry practices?

Producer or Employee Departures: What portion of subsequent client movement can reasonably be attributed to the departure versus other factors?

I do not offer legal advice.
My opinions address industry practices and the business impact of alleged actions on
client retention, revenue, and enterprise value.
