A trio of Ropes & Gray litigators have quietly launched a new litigation boutique catering to the investment management industry.

John Ertman, a longtime partner at Ropes in New York, and Caleb Dulis and Julian Helisek, who were associates, formed Ertman Dulis & Helisek in early February to offer conflict-free counsel to investment managers, their portfolio companies and other entities that are defending against or initiating litigation.
