Kathi M. Sandweiss

Kathi Sandweiss, a former award-winning television journalist, now enjoys a combined arbitration and appellate practice. She is a partner at Jaburg & Wilk, P.C., where she has practiced law over 30 years. Since 2016, Kathi has been an active commercial arbitrator on the roster of the American Arbitration Association. Her AAA cases have included complex asbestos trust claims, franchise agreements, service agreements, landlord/tenant disputes, emergency injunctive relief in a cannabis dispute and multiple consumer claims. She served as sole arbiter on a complex commercial case, with over $1.4 million in dispute, involving issues of breach of contract, UCC and agriculture law. She is currently chair of a three-arbitrator panel in a complex multi-state arbitration. In her capacity as an AAA neutral, she has addressed various procedural issues, including arbitrability, attorney disqualification, jurisdiction and discovery disputes.

She is on the Alternative Dispute Resolution Executive Council, State Bar of Arizona. She presented a seminar on arbitrability at the 2021 State Bar Convention and has written on the issue of delegation clauses in arbitration agreements – “Putting the Shine on Schein.”

Her arbitration practice is enhanced and enlightened by years of appellate experience – she has filed more than 150 appellate briefs and petitions for review in the Arizona Court of Appeals, the Arizona Supreme Court, the Bankruptcy Appellate Panel, the Ninth Circuit Court of Appeals and the U.S. Supreme Court, and has 23 published opinions.

Kathi is a 1977 graduate of UCLA, a 1986 graduate of ASU College of Law, a long-time (albeit slower) long-distance runner and proud Savta to Felix and Fiona.
