Re:  Registration Statement on Form S-8 Under the
     Securities Act of 1933

Ladies and Gentlemen:

     We have examined the Registration Statement on Form S-8
to be filed by you with the Securities and Exchange
Commission on or about the date hereof (the "Registration
Statement") in connection with the registration under the
Securities Act of 1933, as amended, of the Employee Stock
Purchase Plan (as to 88,000 shares) (the "Plan" and
"Shares").  As legal counsel for CTC Communications Group,
Inc., we have examined the proceedings taken and are familiar
with the proceedings proposed to be taken by you in
connection with the issuance and sale of the Shares pursuant
to the Plan.

     It is our opinion that the Shares, when issued and sold
in the manner described in and required by the Plan, will be
legally and validly issued, fully-paid and non-assessable.

     We hereby consent to the use of our opinion as herein
set forth as an exhibit to the Registration Statement and to
the use of our name under Item 5, Interest of Named Experts
and Counsel, in the Registration Statement.  Leonard R.
Glass, Esq., a member of this firm, is a stockholder of CTC
Communications Group, Inc.


               Very truly yours,
