Wendel, Rosen, Black & Dean is a midsize law firm doing the green thing — inside and out.

Not only does the 60-attorney firm take extraordinary measures — including the installation of waterless toilets — to conserve and sustain resources at its Oakland, Calif., office, but it also has steadily built a practice that advises clients on doing the same. The law firm’s progressive position has brought recognition from its community and business for its attorneys.
