Kate’s practice is solely focused on defending health care providers.  She was selected as the 2023 “Lawyer of the Year” in Medical Malpractice Law – Defendants in Phoenix with Best Lawyers.  She is also a Fellow of the American College of Trial Lawyers (,  which is extended only by invitation, after careful investigation, to those experienced trial lawyers who have mastered the art of advocacy and whose professional careers have been marked by the highest standards of ethical conduct, professionalism, civility and collegiality. Membership can never be more than 1% of the total lawyer population of any state or province. Kate was Chair of the Arizona State Committee of the ACTL for the 2021-2023 term after serving as Vice Chair from 2019-2021.  She was lead trial counsel in a 2019 multi-million dollar medical malpractice/wrongful death case that was recognized as a Significant Defense Verdict in Arizona Attorney Magazine, a publication of the State Bar of Arizona.  She has been recognized by The Best Lawyers in America in the practice area of Medical Malpractice Law- Defendants since 2020. 

To date, Kate has first-chaired dozens of trials, including trials in Maricopa, Yavapai, Pinal and Pima Counties, and continues to sustain a heavy trial calendar. Her jury trials have involved the defense of physicians of many different specialties, dentists, hospitals and assisted living facilities.

Kate grew up in the suburban D.C. area, moving to Arizona to attend the University of Arizona in Tucson. She graduated with a B.A. in English and Political Science in 1996 and then went on to earn her J.D. from the University of Arizona in May 1999. Immediately after law school, Kate clerked for the Hon. Michael Cruikshank in Pima County. She then moved to Phoenix to join the Maricopa County Attorney’s Office as a Deputy County Attorney. Kate prosecuted hundreds of felonies, including numerous jury trials, in the three years she spent working for the County Attorney’s Office.

Kate left the County to begin her civil litigation practice and found her niche defending health care providers when she joined the firm in 2005. She became a partner in 2011 and was then elected to shareholder in 2015.
