                         THE SARBANES-OXLEY ACT OF 2002

I, Donald J. Puglisi, Managing Trustee of Equity Securities Trust I, certify
that:

1.    I have reviewed this report on Form N-CSR of Equity Securities Trust I;

2.    Based on my knowledge, this report does not contain any untrue statement
      of a material fact or omit to state a material fact necessary to make the
      statements made, in light of the circumstances under which such statements
      were made, not misleading with respect to the period covered by this
      report;

3.    Based on my knowledge, the financial statements, and other financial
      information included in this report, fairly present in all material
      respects the financial condition, results of operations, changes in net
      assets, and cash flows (if the financial statements are required to
      include a statement of cash flows) of the registrant as of and for, the
      periods presented in this report;

4.    As the registrant's certifying officer, I am responsible for establishing
      and maintaining disclosure controls and procedures (as defined in Rule
      30a-2(c) under the Investment Company Act of 1940) and internal control
      over financial reporting (as defined in Rule 30a-3(d) under the Investment
      Company Act of 1940) for the registrant and have:

      (a)   Designed such disclosure controls and procedures, or caused such
            disclosure controls and procedures to be designed under my
            supervision, to ensure that material information relating to the
            registrant, including its consolidated subsidiaries, is made known
            to me by others within those entities, particularly during the
            period in which this report is being prepared;

      (b)   Designed such internal control over financial reporting, or caused
            such internal control over financial reporting to be designed under
            my supervision, to provide reasonable assurance regarding the
            reliability of financial reporting and the preparation of financial
            statements for external purposes in accordance with generally
            accepted accounting principles;

      (c)   Evaluated the effectiveness of the registrant's disclosure controls
            and procedures and presented in this report my conclusions about the
            effectiveness of the disclosure controls and procedures, as of a
            date within 90 days prior to the filing date of this report based on
            such evaluation; and

      (d)   Disclosed in this report any change in the registrant's internal
            control over financial reporting that occurred during the
            registrant's most recent fiscal half-year that has materially
            affected, or is reasonably likely to materially affect the
            registrant's internal control over financial reporting; and



5.    As the registrant's certifying officer, I have disclosed to the
      registrant's auditors and the audit committee of the registrant's board of
      directors (or persons performing the equivalent functions):

      (a)   All significant deficiencies and material weaknesses in the design
            or operation of internal controls which could adversely affect the
            registrant's ability to record, process, summarize and report
            financial information; and

      (b)   Any fraud, whether or not material, that involves management or
            other employees who have a significant role in the registrant's
            internal control over financial reporting..
