When you’re dealing with a workplace injury, you need someone who understands exactly how to navigate the system and move your case forward. Marc S. Wiesner represents injured workers across California with responsive, client-first communication and advocacy.
Background & Experience
Marc has been practicing law for over a decade, with 12 years dedicated specifically to workers’ compensation. Early in his career, he worked in medical malpractice, where strict limitations on claims often meant turning away individuals who needed help. That experience pushed him to identify a practice area where he could make a broader impact.
After running his own firm handling personal injury, employment, and criminal defense cases, Marc was introduced to workers’ compensation by a mentor. That single case confirmed he had found the right fit: an area of law where he could advocate directly for the people who keep our nation running and help them secure the benefits and care they need and deserve.
Education & Credentials
Marc earned his law degree from Santa Clara University School of Law in 2013 and is licensed to practice in California. He is currently awaiting results for designation as a Certified Specialist in Workers’ Compensation Law through the State Bar of California. He is also an active member of both the California Applicants’ Attorneys Association and the California Lawyers Association, through which he stays connected to developments in the field.
Leadership in the Legal Community
Professional Involvement
Marc regularly contributes to the legal community through mentorship. He has presented at the California Applicants’ Attorneys Association statewide convention and participates in the Santa Clara University School of Law Public Interest JD Program. Marc also volunteers as a mock trial scorer for high school students through the Santa Clara County Bar Association. His work has earned him recognition as an Avvo Top Contributor, reflecting his commitment to supporting both clients and peers.
Approach & Philosophy
When you work with Marc, you can expect clear communication, thoughtful strategy, and a focus on moving your case forward efficiently. He prioritizes responsiveness and accessibility, typically communicating by email or phone to ensure you stay informed at every stage. Marc is supported by our firm’s proprietary systems that streamline administrative work and allow more focus on your case. He believes in breaking through the red tape that often delays medical treatment and benefits, while helping you understand what to expect throughout.
Personal Motivation
Marc is driven by a commitment to protecting hardworking individuals and holding insurance companies accountable. He understands that behind every claim is a person trying to simply recover, support their family, and move forward. That perspective is personal. Growing up, Marc was close to a family friend who worked as a mechanic, a physically demanding job where injuries were common. He regularly saw his hands cut, crushed, and worn down from years of labor, yet like many workers, he kept going back to work as quickly as possible. Marc understands that not everyone has that option. When a serious injury prevents you from returning to work, the system becomes much harder to navigate, and that’s where he focuses his efforts.
Community Involvement
Outside of his legal work, Marc remains involved in his community. He previously served on the board of Hillel Silicon Valley and currently serves on the board of Jewish Silicon Valley. His commitment to service extends well beyond the courtroom.
