Triunity Law Group

TriUnity Law is a law firm serving startups, growth-stage companies, and their investors, with a strong focus on life sciences and other innovation-driven industries. Founded nearly 10 years ago, our firm brings together a team of 10 attorneys with deep experience across law, science, and business—including backgrounds in clinical operations, biology, chemistry, and finance. Our founders, Michael Rivard and Wendy Rieder, each have over 30 years of combined experience in Big Law and in-house roles at life sciences companies. That perspective shapes the way we practice: practical, strategic, and grounded in how businesses actually operate. We’re best known for our work on routine biotech contracts and transactional agreements—partnering closely with clients on commercial, SaaS, and IP contracts, financings, M&A, equity matters, and corporate formation. With a lean structure and low overhead, we deliver responsive, partner-level service—often at well below half the hourly rates of traditional Boston firms, without compromising on quality. Our clients range from first-time founders to publicly traded companies, and we’re proud to serve as long-term advisors across every stage of growth.
