Marin Janitorial - Commercial Cleaning - Cathleen and Robin

Marin Janitorial - Local, Insured, trustworthy


On New Year’s Day 1980, a native Californian man began cleaning Smitty’s Bar in Sausalito. Today, 40+ years later, Robin Clark and his wife Cathleen, owners of Marin Janitorial,, and Pacific Window Cleaning & Janitorial, Inc. are still on the scene and heads up a loyal, tenured group of employees with a long list of happy clients, including his first client – Smitty’s Bar. Cathleen joined her husband in the office after leaving a post with S.O.S. Transportation, and prior key roles with H.K. Ferguson Engineering and with Estate Planning Attorney, Wayne H. Gilbert.

The janitorial and window cleaning services provided have gone from that guy with a floor machine in the back of his van, to owning an established, fully insured and reputable business cleaning service in Southern and Central Marin. Today, Marin Janitorial has achieved a good balance of being large enough to offer professional and fully insured cleaning and janitorial services, yet remaining manageable to offer one-on-one care with all of its clients.


To provide and to maintain a high level of confidence and satisfaction among business owners, managers and residents who trust Marin Janitorial with their cleaning needs. Rather than transactional cleaning services, Marin Janitorial believes in the establishment and nurturing of long-lasting business relationships with its clients.

Robin and Cathleen firmly believe their core values lead Marin Janitorial on the right path to honor its mission.
