List of Registered Medical Supervisors

California’s Medical Supervision Program is a biomonitoring program that measures cholinesterase activity in blood samples collected from agricultural workers who regularly handle category I and II organophosphate and carbamate pesticides.  A new law that took effect January 1, 2017 requires employers to contract only with physicians registered with the Office of Environmental Health Hazard Assessment (OEHHA) for this Program. 

Listed below are the names of physicians who have registered with OEHHA.  The list will be updated as new registration forms are received.

The list is presented in alphabetical order by city in which the clinic is located.  You may also view the list via a map.
