Kathi Sandweiss, a former award-winning journalist and past chair of the Arizona State Bar Appellate Practice Section, is the lead appellate lawyer in Jaburg Wilk’s appellate department. She loves the appellate process – reconstructing convoluted trial records and complicated fact patterns, discussing and distinguishing difficult cases, writing persuasive, winning briefs, and presenting argument to the appellate courts.

Kathi has written over a hundred appellate briefs in the Arizona Court of Appeals, Ninth Circuit Bankruptcy Appellate Panel, U.S. District Court, Ninth Circuit Court of Appeals, Arizona Supreme Court, and United States Supreme Court. She is also a former Judge Pro Tem for Maricopa County Superior Court and former Judge Pro Tem for Scottsdale City Court.

With nearly 30 years of experience writing briefs, Kathi understands the unique challenges of an appeal. Her appellate practice spans the gamut of substantive law including commercial lending, business disputes, large-scale fraud, professional liability, contested probate matters, family law, bankruptcy, and trustee’s sales.  Kathi wrote the amicus brief in the landmark Mid Kansas case and the winning Petition for Review to the Arizona Supreme Court in BT Capital v. TD Service. 

In addition to her successful practice, Kathi is also a commercial arbitrator on the roster of the American Arbitration Association.  Her training in alternative dispute resolution, coupled with her extensive litigation and appeals experience, makes her an efficient and effective neutral.  She can be retained privately or through the American Arbitration Association.

Kathi is co-author of the book “Inside the Minds: Strategies for Consumer Bankruptcy Appeals” and is author and co-author of numerous appellate materials. She regularly presents seminars on Bankruptcy Appeals and Civil Appeals and is a regular faculty member at the Arizona Appellate Practice Institute.  She is also has a blog, That's Appealing and is a blog contributor to the Arizona Attorney Blog network.

Prior to beginning her legal career, Kathi worked for a number of years as an on-air radio and television news reporter. In 1982, she won a Rocky Mountain Emmy for the series "The Phoenix Epidemic."
