Defeat appears to me preferable to total inaction.
-John Adams



Mario Vasta works in our business litigation practice group focusing primarily on civil litigation, including resolving real estate, contract and business disputes. He also represents clients in domestic and international intellectual property (IP) litigation matters, including dealing with trademark applications, opposition, and counterfeiting issues. He’s also the go-to attorney for companies battling scam artists trying to divert their customers to fraudulent websites. Mario utilizes the process under the Uniform Domain-Name Dispute-Resolution Policy – or UDRP – to take down these imposters, while protecting his clients’ vital brand domains.  In keeping with our proud history in water law, Mario’s practice also includes natural resources matters, and his work on behalf of farmers in eastern Arizona has legal precedents dating back to the 1920s.

At the early age of 12, Mario knew he wanted to be an attorney. Encouraged by his mother, who worked as a paralegal, he consistently honed his reading, writing and public speaking skills in his youth. Raised in Upstate New York, he always knew he wanted to head out West, so he drove his Pontiac to Phoenix, Arizona, where he graduated first in his class at Arizona State University’s Sandra Day O’Connor College of Law. Feeling like he found his true calling as a business litigation attorney, Mario takes great satisfaction in working with clients to creatively solve problems and resolve disputes favorably.

When he is not busy at work as a commercial litigation attorney, Mario is usually spending family time with his two-year-old son, his wife, and Australian cattle dog. He recharges his batteries in the great outdoors with activities like hiking and kayaking. An avid reader, Mario has an extensive library in his home where you will find copious amounts of scientific and historical nonfiction titles.
