The antitrust team let by Robin Adelstein is uniquely pragmatic. She attracts top talent to the group and is able to bring in interesting cases and achieve optimal results. Moreover, the team, through Adelstein has a clear focus on antitrust in the life sciences space, giving them an advantage over some peers who focus purely on antitrust, without the very specific focus on life sciences. The team also appropriately staffs cases, but there is always significant oversight by partners‘.

Robin Adelstein is at the top of her game. She brings the pragmatism of an in-house lawyer, spending a large amount of her career working for large companies, including as the United States GC for a large pharmaceutical business. She is tireless in her efforts and understands the needs from an in-house perspective. Antitrust is not always pragmatic, but she brings this practicality to the practice, because she understands how a business needs to operate to be successful. She is always available if necessary‘.
