How we help

We help clients assess, manage, and avoid risk. When litigation is unavoidable, we provide sound, strategic counsel to prepare clients for arbitration proceedings or trials in federal and state courts. Our substantive areas of practice include complex matters involving:


We have substantial experience pursuing and defending civil, criminal, and administrative agency appeals in Arizona and New Mexico courts, other state courts, and federal courts of appeal including the U.S. Supreme Court, the U.S. Court of Appeals for the Federal Circuit, District of Columbia Circuit, and Third, Fourth, Fifth, Sixth, Seventh, Eighth, Ninth, and Tenth Circuits.

Our team handles appeals not only when we have assisted in the trial of a case, but also on referral from outside clients or attorneys seeking new counsel on appeal for a fresh perspective. We provide intelligent and persistent advocacy for businesses and individuals involved in complex serious and high-stakes disputes.

Representing creditors and debtors alike, we are experienced advocates in state, appellate, federal, and bankruptcy courts. We guide corporate and individual debtors through restructurings, negotiate workouts with creditors, and handle bankruptcy proceedings, including Chapter 7 liquidation and Chapter 11 reorganization cases. We help debtors prepare for bankruptcy and develop strategic planning if creditors initiate litigation or an involuntary bankruptcy proceeding.

For creditors, such as local and out-of-state financial institutions, landlords, vendors, prospective asset purchasers, and creditors’ committees, we protect their rights both in advance of a debtor’s insolvency and after a bankruptcy filing. We help them assert their rights in bankruptcy court proceedings.


Successful results in class action suits often turn on a mix of the complex class action procedures and the intricacies of the substantive area of law at issue. We have extensive experience defending companies facing class action and mass action suits in both state and federal courts in Arizona and across the country. Our approach is to emphasize early strategic planning and work efficiently to obtain the best outcome for our clients.

We have litigated matters in state and nationwide class action proceedings for claims involving:

  • Antitrust
  • Unfair competition
  • Breach of warranty or contract
  • Violation of consumer protection and consumer fraud laws
  • Insurance
  • Racketeering

Our substantive experience in class and mass actions in various contexts and claims enables us to advise our clients in both litigation and business strategies to minimize exposure and maximize the likelihood of success for a given dispute.


Whether defending, prosecuting, or arbitrating complex multiparty construction matters, we successfully represent clients before administrative hearing officers, governmental agencies, private arbitrators, and state and federal courts. Areas of expertise include:

We defend employers facing lawsuits in state and federal courts alleging wrongful discharge, whistleblower/retaliation, employee discipline, breach of employment contract, breach of covenant of good faith and fair dealing, wrongful discharge in violation of public policy, and intentional and negligent infliction of emotional distress.

We also counsel employers on federal and state workplace regulatory compliance with such matters as Fair Labor Standards Act (overtime and minimum wage law), Family and Medical Leave Act, and Worker Adjustment Retraining and Notification Act (plant closing statute). We also represent and defend employers in administrative claims and civil litigation before federal and state regulatory agencies, and in private civil actions by current and former employees.

Many of our environmental and natural resources attorneys have formal training and substantive work history in engineering and the sciences, particularly the science associated with regulated substances such as heavy metals, mold, asbestos, benzene, pesticides, TCE, and PCBs.

Government entities spend billions of dollars annually purchasing commodities and services from private businesses. These lucrative government contracts are secured through a public purchasing process known as “public bidding” or “procurement.” Once the government makes its award, disappointed bidders or proposers can challenge, or “protest,” its decision.

We have represented both the government and successful bidders in defending against such protests and have represented disappointed bidders in protesting the government’s award. Having the right counsel on your side is critical. Protest timelines move quickly, arguments can be waived if not raised in a timely manner, and bidders or proposers must actively defend their own bids or proposals.

Even after a procurement contract has been awarded, a dispute may arise between the government and the contract awardee, or between the awardee and a subcontractor. Given the unique nature of government contracting, it is critical to meet the government’s contract obligations and establish a positive performance relationship.

Our team advises clients of their rights and responsibilities to help protect their interests and has a successful track record in resolving and litigating contract disputes.
