Mike has led a number of ground-breaking cases, locally and nationally. He was recognized by the National Law Journal in its triennial selection of the “100 Most Influential Lawyers in America.”
For over 25 years, Mike has been considered one of our country’s leading lawyers. In the mid-1980’s, the FDIC selected him to head its litigation against New York, mob-related money broker, Mario Renda. In 1989, he was lead counsel in MDL-834 – the Lincoln Savings/Charles Keating case. At the time, MDL-834 was the largest commercial litigation in U.S. history. In 2000, Mike obtained an $8.25 million settlement against Joe Arpaio and the Maricopa County Sheriff’s Office, one of the largest wrongful death and civil rights settlements in Arizona history. In early 2006, he obtained a $9 million verdict against the MCSO and Maricopa County in another historic wrongful death case. In 2015, Mike had another "Top 10 Verdict." He was lead counsel for the 10K Partnership and obtained $288 million in compensatory damages. That verdict was the largest in Arizona in 2015 according to Arizona Attorney magazine. In 2017 Super Lawyers and SuperLawyers.com named Mike as one of the Top 50 lawyers in Arizona.
In addition to his regional and national litigation successes, Mike has significant international experience in connection with construction contracts, technology exchange contracts, royalty agreements, distributor agreements and sales agreements in Norway, Great Britain, France, the Philippines, Taiwan, South Korea, Hong Kong, Malaysia, Indonesia and Singapore.
In 1995, Mike was retained to pursue Arizona’s then current Governor, J. Fife Symington, III, for fraud in connection with a real estate loan. A few months after his fraud complaint was filed, the governor was indicted on 23 counts of fraud which paralleled Mike’s allegations. He successfully tried that fraud/bankruptcy case.
In 2001, Mike achieved the second largest commercial case punitive damages verdicts in Arizona history. The jury awarded his client a defense verdict on claims made against his clients and then awarded over $26 million in punitive damages.
In the summer of 2004, Mike tried back-to-back three-week jury trials. He won both trials with unanimous jury verdicts. His clients in these commercial fraud and breach of contract trials were awarded more than $20 million in damages.
In 2009, Mike successfully concluded a large case against an international union that had threatened to destroy one of Arizona’s legacy businesses if that business did not allow unionization of its employees.
