Before returning to a safety-sensitive position, the employee must:

  1. Complete a SAP evaluation.

  3. Receive SAP authorization.
  4. Pass a return-to-duty test.

I came here for a life scan fingerprint for my real estate application. I was out within 10 minutes. Owner is super nice and welcoming. Didn’t get any weird vibes. I highly would recommend this place for anyone who loves the convenience of fast service.

Came here for my live-scan fingerprinting for an engineering application. A very fast and very personable experience! A bit cheaper than other locations offering the service as well. Would highly recommend.

Great clinic! Very professional, worked diligently and got my blood draws done fast and efficiently. I didn’t even feel anything and I am usually a pretty sensitive guy when I get my blood drawn. Would recommend 10/10
