Our Approach

Providing exceptional Occupational Medical Services and Employer Communication result in cost-effective care. With direct access to medical providers and certified staff, you receive information that can return your employees to their work responsibilities.

Facility and Worksite Visits benefit employers from pre-placement services and regulatory compliance, to risk and injury management by professionals that know your business operations! Physicians and educated professionals in occupational medicine perform this no-charge service to our clients.

On-Site Services performed at your facility positively impact your productivity and bottom-line. Whether meeting corporate or mandated compliancy, the On-Site Service Team delivers the same comprehensive results you have come to expect from the clinical environment.

In addition to services inside your facility, the Mobile Audiogram Trailer provides Audiogram / Hearing Testing, as well as Respirator Fit Tests and Specialty Services at your location with 24 hour scheduled service to meet your production needs.
