To Whom It May Concern:
Mr. David Wolfe has worked for Quality Testing, LLC (QT) since April, 2008 as an intern in our
materials testing laboratory in Gilbert, AZ. As Mr. Wolfe’s manager, I have worked closely with him
and over the past 2 years and am familiar with his work ethic and quality. I know Mr. Wolfe to be an
outstanding young man, exhibiting characteristics of honesty, intelligence and competency that are
well appreciated in the work place.
During the time that Mr. Wolfe has worked for our company, he has been working in the laboratory
performing materials testing on soil and concrete construction materials. In this capacity, he has
proved himself to be a valuable asset to our operation. Mr. Wolfe was able to work independently with
minimal supervision in an often fast paced and highly erratic working environment. As an intern in our
lab, Mr. Wolfe was tasked with learning and being able to perform many tests that require a
substantial level of precision. In addition to simply learning and performing these tests, Mr. Wolfe
often identified ways to improve our laboratory operation.
While our specific field of work is in the civil engineering industry, I would personally recommend Mr.
Wolfe for employment in any field. If you have any questions, please don’t hesitate to contact met at
(480) 496-2000.
Sincerely,
Jeffery M. Schaper, PE (AZ #49950)
