Item 4.01.  Changes in Registrant's Certifying Accountant
On July 8, 2016, Dynatronics Corporation ("Registrant") filed its original Current Report on Form 8-K to report certain events relating to the pending resignation of Mantyla McReynolds LLC ("Mantyla"), as the independent registered public accounting firm of the Registrant.  Mantyla had previously announced that it would be merging with BDO USA, LLP ("BDO"), effective as of July 1, 2016.
(a)            The purpose of this Amendment No. 1 is to report that Mantyla merged with BDO on July 1, 2016 (the "Merger").  On July 21, 2016, Registrant received written notice that as a result of the Merger, Mantyla would not complete the audit of the Registrant's financial statements for the fiscal year ended June 30, 2016, and would not stand for reappointment as the Registrant's independent registered public accountants for the fiscal year ending June 30, 2017.  Effective July 21, 2016, the Registrant, after review and approval of the Registrant's Audit Committee, appointed BDO as the Registrant's new independent registered public accounting firm for and with respect to the fiscal year ended June 30, 2016.
Mantyla's reports on the Registrant's financial statements as of and for the fiscal years ended June 30, 2015 and 2014 did not contain any other adverse opinion or disclaimer of opinion and were not qualified or modified as to uncertainty, audit scope or accounting principles.
During the Registrant's fiscal years ended June 30, 2015 and 2014, and through July 21, 2016, there were no disagreements between the Registrant and Mantyla on any matter of accounting principles or practices, financial statement disclosure, or auditing scope or procedure, which disagreements, if not resolved to the satisfaction of Mantyla, would have caused Mantyla to make reference to the subject matter of the disagreements in connection with its audit reports on the Registrant's financial statements.  During the Registrant's past fiscal years ended June 30, 2015 and 2014 and the interim period through July 21, 2016, Mantyla did not advise the Registrant of any of the matters specified in Item 304(a)(1)(v) of Regulation S-K.
The Registrant provided Mantyla with a copy of this report on Form 8-K in accordance with Item 304(a) of Regulation S-K prior to its filing with the Securities and Exchange Commission and requested that Mantyla furnish the Registrant with a letter addressed to the Securities and Exchange Commission stating whether it agrees with the above statements and, if it does not agree, the respects in which it does not agree.  A copy of the letter from Mantyla is filed as Exhibit 16.1 hereto.
(b)          During the Registrant's two most recently completed fiscal years and through the date of engagement of BDO, neither the Registrant nor anyone on behalf of the Registrant  consulted with BDO regarding (a) the application of accounting principles to a specified transaction, either completed or proposed, or the type of audit opinion that might be rendered on the Registrant's financial statements as to which the Registrant received a written report or oral advice that was an important factor in reaching a decision on any accounting, auditing or financial reporting issue; or (b) any matter that was the subject of a disagreement or a reportable event as defined in Items 304(a)(1)(iv) and (v), respectively, of Regulation S-K.
