Brian M. Flaherty

Brian Flaherty is an experienced trial lawyer who believes in the ethical yet aggressive representation of his clients.

He focuses his practice on construction and insurance coverage matters and commonly represents general contractors in disputes with both private owners and the government. He has successfully represented contractors in disputes over prompt payment, change orders, delay damages and termination. He also represents contractors and construction professionals in licensing matters and administrative hearings involving the Arizona Registrar of Contractors and other government agencies.

In addition to being a capable trial lawyer, Brian is often able to successfully resolve disputes without resorting to litigation. But when necessary, he has obtained positive results for clients in arbitrations and trials.

Brian’s insurance coverage practice involves counseling and litigation on behalf of corporate policy holders with respect to designing insurance coverage strategies, advising on policy implications resulting from lawsuits, and breach of contract and bad faith litigation. Additionally, Brian handles litigation for transportation companies, real estate developers, health care providers and other businesses.
