    We offer drug testing services for various needs, including hair, saliva, and urine tests for both DOT-mandated and non-DOT drug screenings. To maintain a drug-free workplace, call (909) 795-4259 to schedule pre-employment screenings for new hires or random drug tests for employees!
  • Remote I-9 verification

    As part of the PSI Test Center Network or through direct employer approval, we offer remote I-9 employee verification services. The employee must complete the first section of the I-9 form, and we will fill out the second section in their presence. During the appointment, the employee is required to present original, non-expired documents that verify their eligibility to work in the U.S. If the I-9 verification is ordered by the employer, we can transmit the completed document via fax or secure email. Otherwise, the information will be reported to the employer through the PSI system.
