Theresa Mak brings nearly 20 years of experience working with employers to navigate the alarmingly complex web of laws and regulations in California.  She has extensive experience litigating wage and hour class, collective and representative actions under the California Private Attorneys General Act (PAGA).


Theresa is dedicated to ensuring that clients receive focused and practical representation in litigation and beyond.  She has been successful in obtaining positive results for clients, including defeating class certification, obtaining summary judgment and resolving matters with high stakes exposure.  She regularly consults with clients regarding the valuation of complex litigation.  She also defends employers against claims of discrimination, harassment, retaliation and wrongful termination, and investigates and responds to claims and charges before the California Labor Commissioner, the California Department of Fair Employment Housing, and the Equal Employment Opportunity Commission.


Prior to joining GBG, Theresa was a partner at Jackson Lewis P.C.  Before Jackson Lewis, Theresa was a senior attorney at Morgan Lewis & Bockius LLP’s employment law practice.  Theresa served as an extern with Judge D. Lowell Jensen of the United States District Court for the Northern District of California.




Theresa, her husband and their two young children live in the East Bay just outside of San Francisco.  They spend a lot of their free time exploring the San Francisco Bay Area.  Theresa loves to travel and is looking forward to a time when traveling with her kids will be actually relaxing.


Theresa has defended numerous class, collective and/or representative actions involving claims related to misclassification, overtime, meal/rest breaks, regular rate, minimum wage, wage statements, waiting time penalties, security screening/bag checks, unreimbursed business expenses and others.  Because complex wage and hour litigation often has far-reaching implications for an employer, Theresa’s defense strategy takes into account the employer’s business goals and other pragmatic considerations.


Theresa works with clients to minimize risk in a state where compliance is challenging.  In most instances, the most comprehensive strategy is to resolve pending litigation and proactively make changes to reduce future risk in a way that meets the company’s business needs.



Theresa will be a panelist at the Alameda County Bar Association Annual Labor & Employment Symposium on the topic of "What is This Case Worth?" on October 26, 2018.
