    1. I have reviewed this annual report on Form 10-KSB of Crdentia Corp.;

    2. Based on my knowledge, this report does not contain any untrue

statements were made, not misleading with respect to the period covered by
this report;

    4. The registrant's other certifying officer and I are responsible for
establishing and maintaining disclosure controls and procedures (as defined
in Exchange Act Rules 13a-15(e) and 15d-15(e)) for the registrant and have:

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

    (b) evaluated the effectiveness of the registrant's disclosure controls
        and procedures and presented in this report our conclusions about

        evaluation; and

    (c) disclosed in this report any change in the registrant's internal
        control over financial reporting that occurred during the
        registrant's most recent fiscal quarter (the registrant's fourth
        fiscal quarter in the case of an annual report) that has materially
        affected, or is reasonably likely to materially affect, the
        registrant's internal control over financial reporting; and;

    5. The registrant's other certifying officer and I have disclosed,
based on our most recent evaluation of internal control over financial
reporting, to the registrant's auditors and the audit committee of the
registrant's board of directors (or persons performing the equivalent
function):

    (a) all significant deficiencies and material weaknesses in the design
        or operation of internal control over financial reporting which
        are reasonably likely to 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 controls over financial reporting.
