-------------------                                           ------------------

Item 1.  Security and issuer.

         The class of equity securities to which this statement relates is the
Common Stock, $.01 par value ("Shares"), of SafeGuard Health Enterprises, Inc.,
a Delaware corporation ("SafeGuard"), with principal executive offices at 95
Enterprise, Aliso Viejo, California 92656.

Item 2.  Identify and background.

         This amendment to Schedule 13D ("Amendment No. 1") amends and
supplements the Statement on Schedule 13D, filed on February 16, 2001, by John
Hancock Financial Services, Inc. and John Hancock Life Insurance Company, by
reason of a merger effected on April 28, 2004. Except as herein supplemented or
amended, all other information in the Schedule 13D is as set forth therein.

         The persons filing this statement are Manulife Financial Services,
Inc., a Canadian corporation ("MFC"), its direct, wholly-owned subsidiary, John
Hancock Financial Services, Inc., a Delaware corporation ("JHF"), and JHF's
direct, wholly-owned subsidiary, John Hancock Life Insurance Company, a
Massachusetts corporation ("JHLICO"), and together with JHF and MFC, the
"Reporting Persons").

         On April 28, 2004, MFC became the sole shareholder of JHF.

     MFC's principal business is financial services; JHF's principal business is
financial  services  and  JHLICO's  principal  business is life  insurance.  The
principal  office and  business  address for MFC is located at 200 Bloor  Street
East,  NT-10,  Toronto,  Ontario  M4W 1E5;  JHF and JHLICO  are  located at John
Hancock Place, P.O. Box 111, Boston, MA 02117.

         The name, residence or business address and principal occupation or
employment of each of the executive officers and directors of MFC, JHF and
JHLICO are set forth in Attachment A, B and C, respectively. Neither the
Reporting Persons nor any such person has, during the last five years, been
convicted in a criminal proceeding (excluding traffic violations or similar
misdemeanors), or been party to any civil proceeding which resulted in a
judgment, decree or final order enjoining future violations of, or prohibiting
or mandating activities subject to, federal or state securities laws or finding
any violation with respect to such laws.

Item 3.  Source and amount of funds or other consideration.

     In connection with a restructuring of SafeGuard's  debt in 2000,  SafeGuard
issued  shares  of its  Series B  Preferred  Stock and  shares  of its  Series D
Preferred  Stock  (collectively,  the  "Preferred  Stock")  to  JHLICO  and  its
subsidiaries.  Each share of  Preferred  Stock is  convertible  at any time into
Common Stock and,  accordingly,  the  acquisition of the Preferred  Stock may be
deemed to be the acquisition of beneficial ownership of the Shares into which it
may be converted.  The conversion  rate is currently one Share for each share of
Preferred Stock.


-------------------                                           ------------------
CUSIP No. 786444109                  13D                      Page 6 of 19 Pages
-------------------                                           ------------------


     In October  2003,  JHLICO and its  subsidiaries  acquired  $5,000,000 of 6%
Convertible Notes from SafeGuard (the "Notes"). The Notes are convertible at the
election of the holder  into one Share for each $1.75 in  principal  amount,  an
aggregate of 2,857,143 Shares.

         On April 28, 2004, JHFS became a wholly-owned subsidiary of Manulife,
as a result of which Manulife became the ultimate beneficial owner of the
SafeGuard securities held by JHLICO and its subsidiaries.

 Item 4.  Purpose of transaction.

         The transactions requiring the filing of this statement are described
in Item 3 above. The transactions were entered into principally for investment
purposes. In connection with such transactions, Stephen J. Blewitt, a Managing
Director of the Bond and Corporate Finance Group of JHLICO, was elected to
SafeGuard's Board of Directors as the director elected by SafeGuard's Series B,
C and D Preferred Stock. Pursuant to the Agreement Among Shareholders described
in Item 6, JHLICO has agreed to vote to amend SafeGuard's Certificate of
Incorporation to increase the authorized Shares in order to have sufficient
Shares authorized and unissued reserved for issuance upon conversion of various
convertible securities of SafeGuard.

         The Reporting Persons may make purchases of Shares, in the open market
or in private transactions, depending on their analysis of SafeGuard's business,
prospects and financial condition, the market for such stock, other investment
and business opportunities available to the Reporting Persons, general economic
and stock market conditions, proposals from time to time sought by or presented
to them and other factors. The Reporting Persons intend to closely monitor their
investment and may from time take advantage of opportunities presented to them.
They may in the future also formulate plans or proposals regarding SafeGuard,
including possible future plans or proposals concerning events or transactions
of the kind described in paragraphs (a) through (j) below.

         Depending upon the Reporting Persons' continuing review of their
investments and various other factors, including those mentioned above, the
Reporting Persons may (subject to any applicable securities laws and subject to
the Agreement Among Stockholders dated January 31, 2001, described in Item 6)
decide to convert all or any part of the Preferred Stock and/or Notes and/or
sell all or any part of the Preferred Stock or Notes or the Shares received
upon conversion, although they have no current plans to do so.

     SafeGuard has filed  documents  with the SEC in connection  with a proposed
going-private  transaction  that would use a reverse  stock  split to reduce the
number of shareholders  of SafeGuard,  result in the delisting of the Shares and
would permit  SafeGuard to  discontinue  its SEC  reporting  obligations.  It is
expected  that  the  going-private  transaction  would  slightly increase  the
percentage ownership of the Reporting Persons.

         Except as set forth in this Item 4, the Reporting Persons do not have
any plans or proposals which would be related to or result in:

         (a) The acquisition by any person of additional securities of
SafeGuard, or the disposition of securities of SafeGuard;

-------------------                                           ------------------


         (b) An extraordinary corporate transaction, such as a merger,
reorganization or liquidation, involving SafeGuard or any of its subsidiaries;

         (c) A sale or transfer of a material amount of assets of SafeGuard or
any of its subsidiaries;

         (d) Any change in the present board of directors or management of
SafeGuard, including any plans or proposals to change the number or terms of
directors or to fill any existing vacancies on the board;

         (e) Any material change in the present capitalization or dividend
policy of SafeGuard;

         (f) Any other material change in SafeGuard's business or corporate
structure;

         (g) Changes in SafeGuard's charter, bylaws or instruments corresponding
thereto or other actions which may impede the acquisition of control of
SafeGuard by any person;

         (h) Causing a class of securities of SafeGuard to be delisted from a

         (c) No other person is known to have the right to receive or the power
to direct the receipt of dividends from, or the proceeds from the sale of
securities covered by this statement.

Item 6. Contracts, arrangements, understandings or relationships with respect to
        securities of the issuer.

         In connection with the transactions described in Item 3, JHLICO,
JHVLICO and Partners entered into a Registration Rights Agreement with SafeGuard
and certain other stockholders and an Agreement Among Stockholders with certain
other stockholders of SafeGuard. The descriptions below of these agreements are
qualified in their entirety by reference to the agreements, which are filed as
Exhibits 2 and 3 to this Schedule.


         Pursuant to the Registration Rights Agreement, SafeGuard has granted
certain "piggyback" registration rights to the shareholders which are party to
the agreement. The shareholders participating in any such registration statement
have agreed not to effect any other public sale or distribution of the
securities being registered or a similar SafeGuard security or any security
exchangeable or exercisable for such securities during the ten days prior to,
and during the 90-day period beginning on, the effective date of such
registration statement, if and to the extent requested by SafeGuard or the
underwriters of the offering. The parties to the agreement also have agreed to
agree on the same terms applicable to officers and directors of SafeGuard not to
effect any other public sale or distribution of the securities offered in an
underwritten public offering or an offering pursuant to Rule 144A or a similar
SafeGuard security or any security exchangeable or exercisable for such
securities during the ten days prior to, and during the 90-day period beginning
on, the date of the final prospectus included in the registration statement or
of the offering memorandum used in connection with such offering.


         Pursuant to the Agreement Among Shareholders, the parties thereto
agreed that they would not transfer, assign, convey, pledge or otherwise
encumber any shares except subject to and bound by the provisions of the
agreement. The parties agreed to vote to amend SafeGuard's Certificate of
Incorporation to increase the number of authorized Shares to 40 million or more
in order to have sufficient authorized and unissued Shares reserved for issuance
upon the conversion of preferred stock issued by SafeGuard. The parties also
agreed to vote as necessary to maintain the size of the SafeGuard Board of
Directors at seven and to cause Stephen J. Blewitt to be elected to the Board of
Directors as the director elected by the Series B, C and D Preferred Stock. The
agreement also grants certain "drag-along" rights to CAI Partners and Company
II, L.P., CAI Capital Partners and Company II, L.P. and Jack R. Anderson in the
event of a proposed sale of all of SafeGuard's outstanding capital stock.
