“I wanted to personally thank you and all the personnel at MQC Labs for their assistance over the years.  I’ve lost count but, I think 20 plus years would be close.

MQC has assisted [us] with multiple inspection activities over the years, both at our facility and at yours.  The transition of personnel or work between our groups always remained seamless.  I feel this was due in part, to the excellent working relationship we developed over the years but mostly, your groups experience with and understanding of our scheduling needs and NDI requirements.

With your groups assistance, [we] have been successful through multiple customer audits, including those with PRI (NADCAP).  Additionally, your group always found a way to support, even on those short notice calls.  Your support with Level III and II services in penetrant, ultrasonic, radiography and radiation safety made my job a lot easier.”

LeRoy E. Perouty, Responsible Level III

MRA Systems

"I wanted to take a moment to thank MQC Labs for the recent radiographic NDE you performed on our telescope bipods.  It was a difficult job and there were a few very long days wrapped in there, but your crew really did an excellent job.  Please thank [your inspectors] for all the hard work they put in.  All three of them were extremely professional and they represented MQC Labs quite well."

Michael Mulloney

Mechanical Engineer

“MQC does 99% of our NDT inspection.  They are extremely thorough and very responsive.  I would not use anyone else.”
