    Juan Maldonado
  • “I’ve been working with Clean Harbors for some time now and we send all our equipment to Technical Associates for Calibration. In the past 6 months, since we’ve started to directly deal with Sahil, the turnaround for getting our equipment back (after calibration has been done) has significantly improved. Sahil is quick to respond back to my inquiries and he takes care of any concerns we may have in a timely manner.”
