                  (File No. 333-94521)

Ladies and Gentlemen:

         We have acted as special Utah counsel to IASIS Healthcare MSO Sub of
Salt Lake City, LLC (the "Company"), a limited liability company organized and
existing under the laws of the State of Utah and a wholly owned subsidiary of
IASIS Healthcare Corporation, a Delaware corporation ("IASIS"), in connection
with the public offering of up to $230,000,000 aggregate principal amount of 13%
Senior Subordinated Notes Due 2009 of IASIS (the "New Notes") which are to be
guaranteed on an unsecured senior subordinated basis pursuant to guarantees (the
"Guarantees") by each of the wholly owned subsidiaries of IASIS (the Guarantee
of the Company is referred to herein as the "Utah Guarantee"), as set forth on
Schedule I attached hereto (the subsidiary guarantors set forth on Schedule I
attached hereto being collectively referred to herein as the "Guarantors"). We
are informed that the New Notes are to be issued pursuant to an exchange offer
(the "Exchange Offer") in exchange for a like principal amount and denomination
of the issued and outstanding 13% Senior Subordinated Notes due 2009 of IASIS
(the "Old Notes"), as contemplated by the Registration Rights Agreement, dated
as of October 15, 1999 (the "Registration Rights Agreement"), by and among
IASIS, the Guarantors and J.P. Morgan Securities Inc. We are informed that the
Old Notes were issued, and the New Notes will be issued, under an Indenture,
dated as of October 15, 1999, by and among IASIS, the Guarantors and The Bank of
New York, as Trustee (the "Trustee"), as supplemented by a Supplemental
Indenture, dated as of October 25, 1999, and a Supplemental Indenture, dated as
of November 4, 1999 (such Indenture, as supplemented to date, being hereinafter
referred to as the

"Indenture"). We have not taken any action to independently verify the above
information, and are acting solely in reliance upon the information contained in
the documents provided to us and the Officers' and Manager's Certificate
described below as to the accuracy of the forgoing information.

         This opinion is being furnished in accordance with the requirements of
Item 601(b)(5) of Regulation S-K under the Securities Act of 1933, as amended
(the "Securities Act").

         In connection with this opinion, we have examined copies, certified or
otherwise identified to our satisfaction, of (i) an executed copy of the
Indenture; (ii) an executed copy of the Guarantee to which the Company is a
party (the "Utah Guarantee"); (iii) the Articles of Organization of the Company,
as filed with the State of Utah Department of Commerce, Division of Corporations
and Commercial Code; (iv) the Operating Agreement of the Company, as currently
in effect; and (v) certain resolutions adopted by the Manager and Sole Member of
the Company relating to, among other things, the Indenture and related matters.
We have also examined copies, certified or otherwise identified to our
satisfaction, of such records of the Company and such agreements, certificates
of public officials, certificates of officers or other representatives of the
Company and others, and such other documents, certificates and records as we
have deemed necessary or appropriate as a basis for the opinions set forth
herein.

         In our examination, we have assumed the genuineness and authenticity of
all signatures on original documents, the legal capacity of natural persons, the
authenticity of all documents submitted to us as originals, the conformity to
original documents of all documents submitted to us as certified, facsimile or
photostatic copies, and the authenticity of the originals of such copies, and
the due authorization, execution and delivery of all documents, where
authorization, execution and delivery are prerequisites to the effectiveness of
such documents, and the truthfulness of the assertions made in the Officers' and
Manager's Certificate executed on behalf of the Company and IASIS which is
attached to this opinion. As to any fact material to this opinion which we did
not independently establish or verify, we have relied upon statements and
representations of IASIS and the Company and their respective officers and other
representatives and of public officials.

         In rendering the opinion expressed below, we have assumed, without any
independent investigation or verification of any kind, that:

                  (a) except as provided in paragraph 4, below, each of the
Indenture, the Notes, the Utah Guarantee and the Registration Rights Agreement
has been duly authorized, executed and delivered by each party thereto; and
   3

                  (b) each of the Indenture, the Notes, the Utah Guarantee and
the Registration Rights Agreement constitutes the valid and binding obligation
of each party thereto, enforceable against such party in accordance with its
terms.

         Members of this firm are admitted to the Bar of the State of Utah and
we express no opinion as to the laws of the United States or any other
jurisdiction other than the laws of the State of Utah. We express no opinion as
to whether the laws of any particular jurisdiction apply, and no opinion to the
extent that the laws of any jurisdiction other than those identified above are
applicable to the subject matter hereof. We also express no opinion regarding
any securities laws.

         Based upon and subject to the foregoing and the limitations,
qualifications, exceptions and assumptions set forth therein, we are of the
opinion that:

         1.       The Company has been duly organized and is validly existing
                  and in good standing under the laws of the State of Utah.

         2.       The Company has the power and authority to execute, deliver
                  and perform all of its obligations under the Indenture and the
                  Utah Guarantee.

         3.       The execution and delivery of each of the Indenture and the
                  Utah Guarantee and the consummation by the Company of the
                  transactions contemplated thereby have been duly authorized by
                  all requisite action on the part of the Company.

         4.       The execution and delivery by the Company of the Indenture and
                  the Utah Guarantee and the performance by the Company of its
                  obligations thereunder do not and will not violate, conflict
                  with or constitute a breach or default under the Articles of
                  Organization or Operating Agreement of the Company.

         We hereby consent to the filing of this opinion with the Commission as
an exhibit to the Registration Statement. We also consent to the reference to
this firm under the caption "Legal Matters" in the Registration Statement. In
giving this consent, we do not thereby admit that we are included in the
category of persons whose consent is required under Section 7 of the Securities
Act or the rules and regulations of the Commission.

                                   Very truly yours,

                                   SNOW, CHRISTENSEN & MARTINEAU
