About Me

Berntson Law specializes in employment and labor matters. For nearly 15 years, I have advised working professionals on the decisions that matter most—like negotiating salary, employee benefits, and severance agreements/packages.


Working either behind-the-scenes or at the negotiating table, I have built a reputation for finding creative solutions that help working professionals to make smart decisions about their futures. My goal is to resolve matters informally through negotiation, mediation or, if necessary, to help clients decide whether litigation is necessary to protect their rights and professional reputations.


I also provide advice and counsel to small business clients on human resource and compliance issues, and handle business transaction matters.
