ITEM 4. CHANGE IN THE REGISTRANT'S CERTIFYING ACCOUNTANT.

Effective as of September  10, 2002,  Fonar  Corporation  (the  "Company")  as a
result of the recent  merger of several of the  Partners of Grassi & Co.,  CPA's
P.C.  into Marcum & Kliegman,  LLP,  dismissed  Grassi & Co.,  CPA's,  P.C.  and
engaged Marcum & Kliegman,  LLP as its independent  accountant.  The decision to
change accountants was approved by the Board of Directors of the Company.

The Grassi & Co., CPA's, P.C. report on the Company's  financial  statements for
the past two fiscal  years  ended June 30,  2001 and 2000  contained  no adverse
opinion or  disclaimer  of opinion  and were not  qualified  or  modified  as to
uncertainty, audit scope or accounting principles.

During the two most recent  fiscal  years ended June 30, 2001 and 2000,  and the
subsequent   interim   period  through   September  10,  2002,   there  were  no
disagreements  with  Grassi & Co.,  CPA's,  P.C.  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 Grassi &
Co., CPA's,  P.C., would have caused Grassi & Co., CPA's, P.C. to make reference
thereto in their report on the financial statements for such years.

During  the two most  recent  fiscal  years and the  subsequent  interim  period
through  September  10,  2002 there  were no  reportable  events (as  defined in
Regulation S-K Item 304(a)(1)(v)).

During  the two most  recent  fiscal  years and the  subsequent  interim  period
through  September 10, 2002,  neither the Company nor anyone on its behalf,  has
consulted  with Marcum & Kliegman,  LLP regarding (i) either 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  Company's  financial
statements: or (ii) any matter that was either the subject of a disagreement, as
that term is defined in Item  304(a)(1)(iv)  of  regulation  S-K and the related
instructions to Item 304 of Regulation S-K, or a reportable  event, as that term
is defined in Item 304(a)(1) (v) of Regulation S-K.

The Company  provided  Grassi & Co.,  CPA's,  P.C. with a copy of the disclosure
made under this Item 4 of Form 8-K and has requested  that Grassi & Co.,  CPA's,
P.C.  furnish  it  with a  letter  addressed  to  the  Securities  and  Exchange
Commission stating whether or not it agrees with the above statements. A copy of
such  letter,  when  received,  will be filed by amendment as Exhibit 16 to this
Form 8-K.


ITEM 7. FINANCIAL STATEMENTS AND EXHIBITS.

Exhibit 16. - Letter from Grassi & Co. CPA's, P.C.: See Exhibits.
