CONSENT OF INDEPENDENT REGISTERED PUBLIC ACCOUNTING FIRM


         We consent to the incorporation of our report dated March 18, 2004, on
the financial statements of Centrex, Inc. (the "Company") at December 31, 2003,
for the period from inception (October 6, 1998) to December 31, 2003, and for
the years ended December 31, 2003 and 2002, included in this Registration
Statement of Centrex, Inc. on Form S-8.

         Our report, dated March 18, 2004, contains an explanatory paragraph
that states that Centrex, Inc. is a development stage company with insufficient
revenues to fund development and operating expenses, which raises substantial
doubt about its ability to continue as a going concern. The financial statements
do not include any adjustments that might result from the outcome of that
uncertainty.
