Vivien B. Williamson brings impressive and extensive experience in mediation to Signature Resolution, having mediated cases since 1987. ​Her background spans an array of practice areas, including employment, civil rights, real estate, insurance coverage, and commercial contracts. Ms. Williamson’s deep understanding of high-intensity cases makes her an ideal candidate to guide litigants to fair, successful resolutions.  ​

Known in the industry as a coveted independent mediator, Ms. Williamson has built a reputation for having close relationships with attorneys in her network, relentlessly pursuing appropriate outcomes, and showing the utmost care and respect for clients. This service-focused mindset is an invaluable asset in the neutral setting.  ​

In addition, Ms. Williamson has experience teaching mediation and negotiation at Hastings College of the Law as well as other law schools and universities. She has conducted mediator and mediation advocacy training seminars for bar associations, law firms, and other organizations across the country.

These accomplishments, along with mediating thousands of cases throughout her industry tenure, have allowed Ms. Williamson to hone her craft as a neutral over nearly four decades. Her expertise, compassion, and empathy help clients feel comfortable, safe, and heard throughout the mediation process.​

As Ms. Williamson describes it, she is motivated by her belief that education is key to helping people and parties make better decisions, and she sees the law—specifically, mediation—as a means to this end. Ms. Williamson is devoted to being of service to the attorneys and litigants she works with, constantly aiming to facilitate outcomes that result in substantive, procedural, and psychological satisfaction for all parties. ​

In joining Signature Resolution, Ms. Williamson hopes to expand her community of fellow neutrals, supporters, and constructive critics so ​that she can continue to learn and grow in her practice.
