POWER OF ATTORNEY

The undersigned, being a person required to file reports pursuant to
Section 16 of the Securities Exchange Act of 1934 ("Section 16")
regarding the undersigned's beneficial ownership of equity securities in
Mistras Group, Inc. (the "Company"), hereby constitute and appoint each
of Michael Keefe, Edward Prajzner and Michael Kozole, signing singly,
as my true and lawful attorney-in-fact to:

(1)	prepare, execute in my name and on my behalf, and submit to the
U.S. Securities and Exchange Commission (the "SEC") a Form ID, including
amendments thereto, and any other documents necessary or appropriate to
obtain codes and passwords enabling me to make electronic filings with
the SEC of reports required by Section 16 or any rule or regulation
of the SEC;

(2)	execute for and on my behalf, as a Section 16 reporting person of
the Company, Forms 3, 4, and 5 in accordance with Section 16 and the rules
thereunder, and any other forms or reports I may be required to file in
connection with my ownership, acquisition, or disposition of securities of
the Company;

(3)	do and perform any and all acts for and on my behalf which may be
necessary or desirable to complete and execute any such Form 3, 4, or 5,
or other form or report, and file such form or report with the SEC and
any stock exchange or similar authority; and

(4)	take any other action of any type whatsoever in connection with the
foregoing which, in the opinion of such attorney-in-fact, may be to my
benefit, in my interest, or legally required by me, it being understood
that the documents executed by such attorney-in-fact on my behalf pursuant
to this Power of Attorney shall be in such form and shall contain such
terms and conditions as such attorney-in-fact may approve in such
attorney-in-fact's discretion.

	I hereby grants to each such attorney-in-fact full
power and authority to do and perform any and every act and thing whatsoever
requisite, necessary, or proper to be done in the exercise of any of the
rights and powers herein granted, as fully to all intents and purposes as
I might or could do if personally present, with full power
of substitution or revocation, hereby ratifying and confirming all that
such attorney-in-fact, or such attorney-in-fact's substitute or substitutes,
shall lawfully do or cause to be done by virtue of this Power of Attorney
and the rights and powers herein granted. I acknowledge that the foregoing
attorneys-in-fact, in serving in such capacity at my request, are not
assuming, nor is the Company assuming, any of my responsibilities to comply
with Section 16.

	This Power of Attorney shall remain in full force and effect until the
undersigned is no longer required to file Forms 3, 4, and 5 with respect to my
holdings of and transactions in securities of the Company, unless earlier
revoked by me.  By executing this Power of Attorney, I revoke all powers of
attorney previously executed by me regarding the powers and authority granted
in this Power of Attorney.
