Ladies and Gentlemen:

At your request, I have examined the registration statement on Form S-3 to be
filed by Moore Medical Corp., a Delaware corporation (the "Company"), with the
Securities and Exchange Commission on or about April 26, 2001 (the "registration
statement") relating to the registration under the Securities Act of 1933, as
amended, of 182,258 shares of the Company's common stock, $.01 par value (the
"Shares"), being offered by certain selling shareholders specified therein (the
"Selling Shareholders").

As counsel to the Company, I have examined the proceedings taken by the Company
in connection with the offering by the Selling Shareholders of up to 182,258
Shares.

In my opinion the 182,258 Shares are legally and validly issued, fully paid and
nonassessable.

I consent to the use of this opinion as an exhibit to the registration statement
and further consent to all references to me in the registration statement, the
prospectus constituting a part thereof, and any amendments thereto.

                              Very truly yours,


                              /s/ Joseph Greenberger

                                     EX-1
