Cosmo Mastanduno

Puppy-At-Law

Cosmo Mastanduno, Mastanduno Law Group, Portland, Oregon

Filling out our legal team is Cosmo, Steven’s dog and our firm’s youngest member. Cosmo was born in 2025 and has been with the firm since then, quickly rising through the ranks and establishing himself as our firm’s greatest morale booster. Cosmo brings equal parts charm, curiosity, and playfulness, and takes his responsibilities very seriously. When not supervising our firm, Cosmo can be found jumping up on visitors, offering his emotional support, and conducting important patrols for head rubs and treats. With bright eyes, perky ears, and a knack for stealing hearts in record time, Cosmo has quickly become one of our favorite colleagues. Outside of the office, Cosmo enjoys long neighborhood walks, cozy naps, and skittering on hard wood floors.

In the courtroom, as in life, I speak not in arguments, but in inevitabilities.
