The question isn't who is going to let me; it's who is going to stop me.
-Ayn Rand


Andrea Marconi is an experienced litigator and serves as Chair of the firm’s business litigation practice group. Her broad spectrum of work encompasses many areas, including complex commercial litigation, franchise litigation and banking issues such as payment processing, credit card processing and ACH transactions. In addition, Andrea has experience with entities throughout the healthcare industry, including representing health insurers and medical billing companies in numerous matters such as coverage issues, regulatory and compliance matters, and defense of bad faith claims. Routinely arbitrating and contesting cases in state and federal courts around the country, she also has extensive experience litigating a wide array of real estate contract disputes, insurance coverage and indemnity matters, restrictive covenants, and trade secret litigation.

Although she did not come from a family of attorneys, Andrea knew early on her calling was to be an attorney. She has always loved analyzing problems, persuading others as to her opinion on the facts and arguing with her father — and often winning — at the kitchen table. As a business litigation attorney, she now advises a diverse group of clients, including individuals, small and mid-sized businesses, and Fortune 500 companies.

She litigates disputes from start to finish — and often resolves these cases before they need to be addressed in the courthouse. She continues to study the art and science of disagreements, and how to best solve them, which is often conducive to long-term relationships with her clients. She frequently takes the role of outside general counsel, looking at ways of avoiding ambiguity that could lead to costly disputes in the future. While not afraid to fight when necessary, Andrea’s approach throughout her career as a business litigation attorney has been to learn her clients’ business inside and out, understanding critical issues and proactively handling any problems in an efficient and cost-effective manner.

When not litigating, Andrea is probably volunteering in the community. Her passion for animal welfare is showcased in her efforts as the chair of the Arizona Humane Society’s board of directors, and her enthusiasm for hoops is evidenced by her seat on the Phoenix Suns Charities 88 Big Gorilla board of directors. Her two sons are her pride and joy, and her weekends are spent at their numerous basketball and soccer events.
