Heat Illness

On-Site was founded in 1996 by Virginia Siegel, CEO and Zulema Garcia, CFO. They started their mission in the San Francisco Bay Area, California, providing only drug testing services to the local refineries during shutdowns.

One foreign body in the eye later… and their idea for a 24-hour mobile first-aid response was born. Like most ground-breaking businesses, the path held many challenges along the way, but by keeping their core values of respect, responsibility, and honesty in the forefront, On-Site has continued to provide the finest mobile health and safety services available to employers.

Over the years, the list of services has grown to include: 24-hour first-aid response, respiratory services, drug testing, audiometric services, training classes, and much more! On-Site has expanded into numerous states across the country and continues to strive towards a nationwide reach.

On-Site's diverse list of services include: 24-hour first-aid response, respiratory services, drug testing, audiometric services, and a host of others that encompass a broad spectrum of health and safety services to meet the needs of any company...large or small.
