Our story

Sunstar Supply Company was founded in 1994 by the Park family with a simple goal: to provide reliable, affordable janitorial supplies while building lasting relationships within the community. Located in the heart of Fremont, California, the company was created to serve local businesses, schools, hospitals, and households with dependable products and personalized service.

Founded by Mr. William Park, Sunstar Supply Company began as a small family-owned operation offering a limited range of cleaning supplies and janitorial equipment. Through dedication, hands-on service, and a strong focus on quality, Mr. Park earned the trust of customers and suppliers alike. As word spread, the business grew steadily through referrals and long-term partnerships.

Expanding to Serve the Bay Area
As demand increased, Sunstar Supply recognized the need to serve its growing customer base better. This led to a move to San Jose, California, providing the company with the space and resources to continue delivering fast, reliable service across the region—including same-day, next-day, and emergency deliveries.

Growing With Our Community
Over the years, Sunstar Supply Company has continued to expand its product offerings and services to meet the evolving needs of the Bay Area. While the business has grown, its commitment to customer care and community support has remained unchanged.

Today, more than 30 years later, Sunstar Supply Company continues to thrive as a second-generation, family-run business. The Park family remains actively involved in daily operations, ensuring every customer receives the same level of care and attention that defined the company from the beginning.
