Diversified Management Services Inc. wishes to convey our sincerest gratitude to our clients for their unwavering support as we celebrate our twenty-fifth year in business.

On October 1, 2018 we began our 25th year of establishment.  We would like to thank all of our loyal clients for being an earnest part of DMS, Inc.’s growth.


DMS started business on October 1, 1993 as a part-time sole proprietorship owned by Theresa Schwager. On January 1, 1999 it became a full-time sole proprietorship.  On Oct. 1, 2003 it became a Corporation.  Theresa Schwager still owns the venture and is President of the Corporation.
