Christopher G. Mackaronis principal

Christopher Mackaronis combines a passion for problem solving with a tenacious approach to trial work, and a hands-on, collaborative style. For over 30 years, Chris has defended clients in commercial and employment disputes of varying complexities in both state and federal courts, and often in front of juries. Chris begins each client relationship by establishing partnership, before specific problems arise. In this way, he can add considerable value to clients’ business activities and help them avoid disputes. When disputes occur, Chris rolls up his sleeves to strategize on the best course of action and to develop creative solutions. And, should litigation proceed, he works vigorously to pursue his clients’ goals and maximize their likelihood of success at trial.

Chris has extensive experience in employment counseling and litigation, including  federal and state anti-discrimination laws and all forms of workplace harassment, representation in EEO proceedings, issues related to employee benefits and pension plans, and non-compete agreements. He has also litigated cases involving theft of trade secrets, claims of misappropriation and breach of fiduciary duty. In addition to chairing numerous jury trials, Chris has represented clients before numerous federal Courts of Appeals and moves comfortably from trial to appellate advocacy. His clients, which include multi-national corporations, national and regional commercial businesses, and professional and trade associations in industries as diverse as publishing, healthcare, nutrition, construction, and energy, appreciate his strategic vision and his ability to guide them through every step of the litigation process.

Much of the foundation for Chris’ extensive practical knowledge in the workplace arena was developed during his work for the Equal Employment Opportunity Commission and then the five years he spent as head of advocacy at the American Association of Retired Persons (AARP). In that role, he represented AARP and its employed members working with external counsel to pursue actions and submit amicus curiae briefs  (friend of the court). This experience was invaluable in equipping Chris with first-hand knowledge of the employment challenges faced by his clients on a daily basis.

PRESENTATIONS & PUBLICATIONS

Chris has been a frequent speaker to organizations such as the Equal Employment Advisory Council, the ERISA Industry Committee and the national Chamber of Commerce.

He has appeared frequently as a guest on local and national television to speak on employment matters, and has been interviewed and quoted extensively in the national news by the New York Times, the Wall Street Journal, the Washington Post and the Los Angeles Times.
