Attorney Profile

Attorney Michael A. Gross focuses his practice in large part on appellate work at both the state and federal levels. As the founder of the Michael Gross Law Office, located in Clayton, Missouri, he represents clients in the greater St. Louis metropolitan area and throughout the state.

In addition to his appellate practice, Mr. Gross regularly consults with trial attorneys, giving them assistance in identifying weaknesses in their adversaries’ cases and helping them write briefs in response to summary judgment and other types of motions.

Mr. Gross has argued federal appellate cases before the U.S. Courts of Appeals for the 2nd, 6th, 7th, 8th, 9th, and 10th Circuits and the Supreme Court of the United States. On the state level, he is admitted to practice in Missouri as well as Arizona, and he has appeared pro hac vice in state trial and appeals courts throughout the country.

The cases that Mr. Gross has handled at the appellate level have included such complex civil matters as mass torts, mergers and acquisitions, legal and medical malpractice, family law, business disputes and product liability, and he has worked on criminal appeals of homicide and other convictions as well. Most of this work has come through referrals from the trial-level attorneys who appreciate and recognize his appellate skills. This is evident from the honors that they have bestowed upon Mr. Gross.
