Who We Are

In 1947, a young veterinarian purchased thousands of rat cages from a Virginia farm and set up a one-man laboratory in Boston, overlooking the Charles River. In an effort to fulfill the regional need for laboratory animal models, he bred, fed and cared for the animals and personally delivered them to local researchers. Today, Charles River looks like a very different company, but in realizing Dr. Henry Foster’s vision, we remain committed to collaboration, responsibility and leadership within the global research community.

In the last six decades, we have seen technologies advance and new diseases emerge. Our one-man laboratory has evolved into a worldwide support network, allowing us to act as a steadfast partner to our sponsors, from discovery to lot release testing. By carefully cultivating our portfolio, our growth has become a continuous strategic effort in anticipating tomorrow’s drug development needs. We can’t predict what the future holds, but at Charles River we continue to kindle the spark that inspired our founding: an urgency to advance human health by supporting our clients’ research every step of the way.


Charles River is committed to providing employee benefit programs and services that promote employee health and wellness. We offer a variety of competitive programs designed to empower our employees with choices and resources to best fit their lifestyle and individual / family needs. Although our benefit programs vary greatly by country, we aim to provide our employees with a comprehensive benefits package that is industry-competitive in the nations where we operate.

    I applied through an employee referral. I interviewed at Charles River Laboratories.


    Primarily had a 30 minute phone interview then was asked to come for an in-person interview. The in-person interview took the whole day where I met with various people in the company and gave a 30 minute presentation on my previous research experiences.
