Based in Winthrop, a suburb of Perth in Western Australia, Winthrop Dexterity Consultants was formed in September 1999 by David & Jennifer Musgrave to provide Dexterity consulting, development and training resources to the Microsoft Business Solutions Great Plains partners around the world.

David came from Sequel Technology where he developed Named Printers which won the 1997 Great Plains Technical Innovation Award, helped Sequel Technology achieve President's Club status in 1999, and was purchased by Great Plains for version 5.50 onwards.

Winthrop Dexterity Consultants soon became well known in the Great Plains community for Omni Tools, a "must have" collection of tools to improve the usability of Great Plains, and Omni Price, the most powerful and flexible customer pricing module available. Sales of these products drove Winthrop Dexterity Consultants to achieve Microsoft Business Solutions President's Club membership in 2001, 2002 and 2004.

Winthrop Dexterity Consultants has provided custom development and consulting to a number of companies worldwide, including development of the Australian Goods and Services Tax (GST) Business Activity Statement (BAS) reporting add-on for Great Plains Australia, and assisting in the development of the GST compliant versions of Great Plains.

David has presented at a number of conferences including the 1998 Great Plains World Wide Developers Conference (WWDC) in Fargo, ND, USA, where he presented a session on Cross Dictionary Development Techniques. These materials were used for a second session at the 1999 Great Plains Developers Conference (GPDC). David presented a third session at the July Great Plains Tech 2000 Conference. At the July Great Plains Tech 2001 Conference, he co-authored the materials for the Pushing the Limits with Dexterity session presented by Mark Rockwell of Rockton Software.

David left the company in May 2001, when he was appointed as the Senior Development Consultant for the Asia Pacific Region by Microsoft Business Solutions. He now works as the Escalation Engineer for the Microsoft Dynamics GP Support Team for the Asia Pacific region. For more information on what David is doing please see the Developing for Dynamics GP MSDN blog.

In December 2001 Microsoft Business Solutions purchased the Omni Security and Omni Field Security modules of Omni Tools and released them for version 7.00 onwards as Advanced Security and Field Level Security.

Jennifer continued to operate Winthrop Dexterity Consultants, selling and supporting Omni Tools and Omni Price, until Rockton Software acquired the products in August 2006.

Moving forward to October 2014 and David left Microsoft and re-launched Winthrop Dexterity Consultants trading as Winthrop Development Consultants.

We look forward to working with you.
