Kathleen has more than 25 years of litigation experience. She assists people in navigating some of the most challenging experiences in life – the failure of a business arrangement, the end of a marriage or the challenge of resolving a difficult relationship with a key employee. She has a unique understanding of how human dynamics affect the resolution of disputes. Kathleen employs both her legal and interpersonal skills to provide incisive and creative legal solutions for her clients.

With a broad-based background in representing technology companies, start-ups and multi-generational businesses, Kathleen has expertise in matters involving copyright, trademark, trade secrets, employment disputes, executive compensation and non-competition agreements. She also counsels executives and entrepreneurs who are changing employment on their legal obligations and rights.
Kathleen was born on Staten Island, New York, to an Irish immigrant and a fourth-generation New Yorker. She attended New York’s prestigious Stuyvesant High School and also received classical ballet training at American Ballet Theatre School. She moved to California to attend Stanford University, where she obtained her A.B. degree in English in 1982. After working as a marketing writer in the computer industry in Silicon Valley, she attended law school at U.C.L.A. and obtained her J.D. in 1986. She spent the first ten years of her career as a litigation attorney in Los Angeles, primarily with Loeb and Loeb and Preston Gates & Ellis LLP. In 1997 she opened the Orange County office of Preston Gates & Ellis and served as that office’s managing partner for five years. She also served on the firm’s compensation committee and the transition committee when the firm merged with another large national firm to become K&L Gates LLP. She left K&L Gates in 2009 to focus on family law and the business litigation issues that arise in those disputes. She received her family law training at Minyard Morris LLP in Newport Beach and opened her own practice in 2011. She joined Cates Peterson LLP as a partner in February 2015 to continue to grow her litigation and family law practice. Kathleen is experienced at using discovery and court procedures to design a litigation plan that will provide the best possible results at the best possible time. Kathleen also has experience in appellate work.
