Dispute Resolution

   

 Alto Litigation is a San Francisco boutique representing industry titans throughout the Bay Area. It is known for its trial-tested ability to dynamically punch well above its weight class against the nation’s largest top firms in several litigation niches, representing prominent companies and entrepreneurs, as well as other individual clients, in both defense and plaintiff roles. Principal among the firm’s specialized areas of representation is its securities practice, which is regularly called upon to represent high-profile clients in a variety of matters, including securities class actions and trade secrets disputes. “We regularly consult with Alto Litigation when we have securities and corporate-governance issues,” testifies a client. “Alto has a team of exceptionally knowledgeable and responsive litigators. They are unusually skilled at seeing every angle to maximize opportunities for a successful outcome.” The firm draws its vitality from founder and visionary securities trial attorney Bahram Seyedin-Noor, who has assembled an elite and talented team of litigators and guided them to prominence in the Golden State. A client calls Seyedin-Noor “astute, experienced, and able to generate creative options and navigate through them.” A peer notes, “Bahram has really cultivated this winning combination of being aggressive and tough while totally maintaining dignity and composure, never a hothead, never a barking dog.” Seyedin-Noor and Bryan Ketroser represented an angel investor in the health technology space, who served as a director of All.Health as a result of an investment by his fund.  When the client voiced concerns about the company’s technology to the other directors, they shut him out of the company. The Alto pair  served inspection demands and, after each was refused, filed suit in the Delaware Court of Chancery to enforce the client’s rights as a director to certain books and records of the company under Delaware law. The Alto team won a decisive trial victory in 2024, All.Health appealed the ruling, and the matter was ultimately settled. Ketroser has also developed a client following. One extols, “Bryan is easy to talk to and personable, and he provides extremely smart and thoughtful advice. He is good at seeing through complex situations and distilling them. Any client would be lucky to have him in their corner.” Another calls Ketroser “extremely organized and very sharp – [he] easily comprehended our very complex case and was able to recall specific details with ease. [He is] Very responsive and easy to talk to, made us feel reassured even when the case became difficult.”
