Our History

CPi Developers founder and San Francisco native Martin Bramante was the son of Italian immigrants. Martin was an enterprising first generation American who had a mind for business and a savvy sense of land value. One of his first acquisitions was San Quentin Disposal, Marin County’s primary landfill, which he operated for 20 years. Martin was well known to generations of Marin children for the lollipops he handed out at the landfill entry. He closed the operation in 1987 and prepared the site for future development.

Martin’s daughter, Susan Bramante Kirby, took the lead in transforming the landfill site into today’s Shoreline Center, adjacent to the San Francisco Bay. She weathered the political challenges of developing in Marin County and over the years won approval for Home Depot, followed by BMW of San Rafael. Susan’s career was cut short in 1999 when she passed away following an illness. Her daughter Stephanie continued the site development efforts and was named company president in 2005.

The business was a true family affair, with Martin’s wife Val and daughters Susan and Kathy working in the operation that grew to include additional commercial and residential real estate projects. His grandchildren Gregory and Gianna Hansen and Stephanie Kirby Plante grew up in the business and became partners in the 1990s.

With Stephanie’s leadership, the family developed Marin Honda at Shoreline Center, then tackled development of the largest Shoreline Center site, proposed for a Target store. After a protracted and grueling political battle, the development plan received city approval. Target San Rafael opened in 2013 and continues to be one of Target’s strongest performing properties.

Martin remained active in day-to-day operations for Cal-Pox, Inc. well into his 90’s. He died in 2014 at the age of 94. Stephanie purchased the company from her family members in 2015 and today is sole owner and continues as president and CEO. In 2016, CPi was recognized for its 45-year membership in the San Rafael Chamber of Commerce and Stephanie was elected to serve as 2017 Chamber Board Chair.
