About Marta

Learn Marta’s areas of practice.

Marta’s main areas of practice are labor and employment law, business law, civil rights law, and general civil litigation. She is a zealous and compassionate advocate for her clients, unafraid to go the extra mile for a successful resolution of their situations. Marta approaches each case with a keen sense of justice and with her immense knowledge of California’s exacting labor and employment statutes.

Marta believes the law is a highly effective conflict-resolution tool and analytical framework. For her, the most rewarding part of practicing law is empowering her clients to move on from the dispute and refocus their lives. Marta takes her role as an advocate seriously by providing innovative, practical approaches to often intractable problems. As the chief strategist of Vanegas Law Group, she oversees the firm’s talented team of attorneys and paralegals to provide excellent and courageous service to their clients.

A native of Budapest, Hungary, Marta calls California home for the past two decades. Prior to private practice, Marta served as Deputy Legislative Counsel in Sacramento, California, drafting legislative proposals and providing counsel to legislators on labor, employment, and business law issues. She also builds on her experience of eight years as a Patent Paralegal at two large San Francisco law firms’ intellectual property practices.

Marta holds a Juris Doctor degree from the UC Davis School of Law (J.D., 2011) and from the ELTE University of Budapest, Hungary (J.D. summa cum laude 1998). She also earned an LL.M. degree in International Business Law from Central European University, Budapest, Hungary (LL.M. with distinction 1999) where she studied, among other things, Comparative European Labor Law and International Commercial Arbitration. While at UC Davis Law School, Marta served as Senior Symposium Editor of the UC Davis Law Review, and as Senior Articles Editor of the UC Davis Business Law Journal and served as the Chair of the Feminist Forum.

Marta is fluent in Hungarian and proficient in Spanish. She is admitted to practice in all courts of the state of California, in the U.S. Northern and Eastern District Courts of California, and in the U.S. Ninth Circuit Court of Appeals. Each year since 2017, Marta has been recognized as a “Rising Star” by Northern California Super Lawyers, an honor reserved for the top 2.5% of attorneys who in the first 10 years of their practice have attained a high degree of peer recognition and professional achievement. Marta frequently presents continuing legal education programs on cutting-edge legal issues.

When not in the office, Marta serves as a Director on the Governing Board of the Contra Costa County Bar Association (CCCBA). Marta is a Past President of the Board of the CCCBA’s Employment Law Section and serves as President of the Business Law Section. Marta is also an Editor of the Contra Costa Lawyer magazine. Marta volunteers on the Parent-Faculty Club of Clayton Valley Charter High School as Parliamentarian and Auditor and serves as a Judge at the UC Davis School of Law Annual Intraschool Negotiations Competition. An avid reader and occasional yogi, Marta keeps herself (somewhat) fit through dancing, gardening, and never-ending home renovations.

Great Attorney
In my first meeting with Marta, she gave me the facts regarding my rights and the strength of the case, and areas that would not benefit the case. I like her knowledge and knowledge of the law in regards to the Department of Fair Housing and Equal Opportunity that protects employees’ rights. My favorite thing about working with Martin & Vanegas, APC was all the staff. They were great at responding to phone calls and emails in a timely manner. They communicate all my questions to Marta and Marta made herself available to respond to emails or set up calls that might need deeper explanations regarding my case. In the end, we were able to go through mediation and Marta was able to request the best mediator. I received a fair settlement in a shorter period of time without needing to go through more emotional distress through a deposition. Marta is a fighter and we were willing to go all the way to court if needed. Her hard work put a value on all the evidence she presented in my case.

Dependable, Brave, and Honest!
A few of my coworkers and I had been mistreated by a former employer. We were scared and uninformed of our rights and what steps to take. Marta's consultation was not only informative, she was exceptionally comforting and kind. Taking the next steps felt terrifying, but Marta made sure to make the process as smooth and comfortable for us as possible. We were VERY happy with the results. THANK YOU, MARTA!

Incompetent and deceptive
Disciplinary complaints by clients, ex clients or opposing counsel for poor representation by Marta Vanegas on her past and present cases are encouraged. Small time non ambitious passive failed attorney Marta Vanegas with minimal understandings is plain lazy who along with not being able to manage her firm or litigation cases can't deliver on accepted cases that require real work from her to do multiple filings, argue with opposing counsel or negotiating reasonable awards on behalf of her client. Without talking to opposition witnesses or discussing with her own clients she assumes a lot and has made up excuses to discontinue her cases for which has earlier agreed to go to trial for. She has been in hiding for two months since last year ignoring client's needs without any communication on their cases, has till today not updated courts on existing cases that she is now part of Jon Webster Law group. Meanwhile Marta Vanegas is seeking excuses to close all her existing cases or offering low negotiation rewards to shut them down all which is announced in her quick 5 minute rushed call talking aggressively with clients to force her final decision on them. She is not telling clients her new and sudden plan of action on cases until she has trapped the client into accepting her as continued attorney of representation via email as she avoids all her client phone calls for ongoing weeks using Jon Webster Law Group answering service as a filter. (Beware of false reviews as shown below that are written herself or paid to be five star reviews)
