Never, never, never give up.
-Winston Churchill


Marc focuses his practice on plaintiffs’ catastrophic injury and wrongful death litigation. He formed the plaintiff personal injury practice at Fennemore and has built it into the strong and innovative practice it is today.

Marc chose personal injury law after spending several years as a defense attorney. He wanted the opportunity to work on a more personal level with clients, and saw personal injury law as the best outlet. Marc has represented thousands of accident victims and their families, resulting in hundreds of successful jury trials, arbitrations, mediations and settlements. He has not only recovered tens of millions of dollars for his clients, he also has proudly forged bonds with them and their families that he expects to endure a lifetime.

Marc is frequently featured on national, regional and local media for comment on legal issues and other current affairs.  Marc has been featured on the cover of  AZ Business Magazine as one of The Top 100 Lawyers in Arizona and highlighted by Newsweek as one of the “20 Leaders Plaintiffs’ Trial Lawyers.” Marc has appeared on CNN, Good Morning America, Today, Fox News, CBS News,, USA Today, and Above the Law. Marc belongs to several Chamber of Commerce organizations.

When not working, Marc spends his time with his wife and sons.
