Katherine Cooper has been a top-producing agent in Piedmont, Oakland, and Berkeley for over 33 years. She is a long-time resident of Piedmont, graduate of Santa Catalina School for Girls and UC Berkeley, proud mother of three (including a developmentally disabled daughter), matriarch, and feminist. Few realtors achieve the level of success that Katherine has enjoyed. An authentic, personable, ethical realtor, her career has been sustained by building lasting, positive relationships with her clients from every walk of life, and years of contributions to her community.

He has a reputation in the industry among clients and agents alike for his hard work, local knowledge, passion for advocacy, analytical ability, and eye for design. His talent for helping clients sell and buy real estate is matched only by his enthusiasm. Jack’s positivity and eternal optimism are at the core of everything he does.
