      (1)   execute for and on behalf of the undersigned, in the undersigned's
            capacity as a director and/or officer of Triumph Bancorp, Inc. (the
            "Company"), Forms 3, 4 and 5 in accordance with Section 16(a) of the
            Securities Exchange Act of 1934, as amended, and the rules
            thereunder (the "Exchange Act"). and Form ID, if necessary, to
            obtain EDGAR codes and related documentation for use in filing Forms
            3, 4 and 5;

      (2)   do and perform any and all acts for and on behalf of the undersigned
            which may be necessary or desirable to complete and execute any such
            Form 3, 4 or 5 or Form ID, complete and execute any amendment or
            amendments thereto, and file such forms with the U.S. Securities and
            Exchange Commission and any stock exchange or similar authority;

      (3)   take any other action of any type whatsoever in connection with the
            foregoing which, in the opinion of such attorney-in-fact, may be of
            benefit to, in the best interest of, or legally required by, the
            undersigned, it being understood that the documents executed by such
            attorney-in-fact on behalf of the undersigned 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; and

      (4)   seek or obtain, as the undersigned's attorney-in-fact and on the
            undersigned's behalf, information regarding transactions in the
            Company's securities from any third party, including brokers,
            employee benefit plan administrators and trustees, and the
            undersigned hereby authorizes any such person to release any such
            information to such attorney-in-fact and approves and ratifies any
            such release of information.

            The undersigned 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 connection with the exercise of
any of the rights and powers herein granted, as fully to all intents and
purposes as the undersigned 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.  The undersigned acknowledges that the
foregoing attorneys-in-fact, in serving in such capacity at the request of the
undersigned, are not assuming, nor is the Company assuming, any of the
undersigned's responsibilities to comply with Section 16 of the Exchange Act.

            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
the undersigned's holdings of and transactions in securities issued by the
Company, unless earlier revoked by the undersigned in a signed writing delivered
to the foregoing attorneys-in-fact.

            This Power of Attorney does not relieve the undersigned from
responsibility for compliance with the undersigned's obligations under the
Exchange Act, including, without limitation, the reporting requirements under
Section 16 of the Exchange Act.  Additionally, although pursuant to this Power
of Attorney the Company will use commercially reasonable best efforts to timely
and accurately file Section 16 reports on behalf of the undersigned, the Company
does not represent or warrant that it will be able to in all cases timely and
accurately file Section 16 reports on behalf of the undersigned due to various
factors and the undersigned's and the Company's need to rely on others for
information, including the undersigned and brokers of the undersigned.

                            [Signature Page Follows]




            IN WITNESS WHEREOF, the undersigned had caused this Power of
Attorney to be executed as of this 9th day of May, 2016.
