              2009 on Form 10-K of Dynatronics Corporation;

         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 and cash flows of the registrant as of, and for, the
              periods presented in this report;

         4.   The registrant's other certifying officer(s) 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)) and internal control over financial reporting (as
              defined in Exchange Act Rules 13a-15(f) and 15d-15(f)) for the
              registrant and have:

                     (a) Designed such disclosure controls and procedures, or
              caused such disclosure controls and procedures 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 report is being
              prepared;

                     (b) Designed such internal control over financial
              reporting, or caused such internal control over financial
              reporting to be designed under our 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
              our conclusions about the effectiveness of the disclosure controls
              and procedures, as of the end of the period covered by 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 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(s) 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 functions):

                     (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 control over financial reporting.
