Von Wobeser y Sierra SC takes its total partner count to 15 with the promotion of two lawyers to partner. The firm has one of the best disputes offerings in Mexico. It is especially well-known for international arbitration, and has opted to fortify its strongest practice area. Arbitration lawyer Montserrat Manzano’s promotion will address the rising number of arbitration cases the firm is handling, according to managing partner Claus von Wobeser. Manzano, 37, has experience advising on public works contracts in the construction and energy sectors, and is the first female partner at the firm.
