Changes are taking place in the management of Lissac, the French optical retail chain acquired by Optic 2000 in 2006. While the group is in the process of selecting a successor for Alain Brugerolle, the brand manager who left in October, it has appointed another former executive of GrandVision, Patrick Liebert, as manager of Lissac's 29 fully-owned stores. Lissac wants to expand its network of 88 franchises.
