Clinical Science Laboratory (CSL), a Massachusetts corporation, was founded in 1974 and has been servicing the needs of communities, hospitals, criminal justice systems, counseling centers, private laboratories, halfway houses, private physicians and

substance abuse programs for over a quarter of a century.

We got our start in Sharon, Massachusetts where Dr. Stanley Elfbaum and Dr. Lou Amoruso converted an old farm house and barn into a laboratory. With much hard work, not long after, we relocated to our new state of the art facility. Today, we employ more than 60 staff members and operate three shifts per day, seven days a week.

That's progress…
