He divested his interest in the firm to take up the CEO position at LADWP. Following his departure form LADWP, Nahai joined the national law firm of Lewis Brisbois Bisgaard & Smith where he co-chaired the firm’s real estate, energy, water, and environmental practice areas. He left Lewis Brisbois to launch David Nahai Associates in 2021.
