Listing Contract Work on Resume

Question
I have done IT contract work directly for an IT company (Company A) and have been hired by staffing companies (Company B and Company C) to do contract work for Company A. Because all my work was performed at and for Company A, can I list the work history one after the other in a chronological resume and then place achievements after to save resume space, or must I place achievements under each company? I am trying to keep my resume within two pages.

For example:

Company C, (Company A contract, ABCD account), McLean, VA
Desktop Support Specialist (2007 - 2008)

Company A, (Contract, ABCD account), Boston, MA
Desktop Support Technician (2006 - 2007)

Company B, (Company A contract, ABCDI account), Norwell, MA
Desktop Support Technician (2005 - 2006)

Company A, (Contract, ABCD account), Boston, MA
Desktop Support Technician (2004 - 2005)

• Wrote clear, detailed work and resolution information in the Remedy Ticketing System, which provided Help Desk and DSS Department technicians with invaluable solutions to problems and enabled management to easily track asset inventory type, brand, model, serial number, and location.
• Authored several technical documents including checklists, which improved consistency between technicians and reduced hardware and software configuration and installation errors.
• Trained and mentored less experienced technicians and interns by providing on the spot training, tips and troubleshooting strategies.

Answer
On your resume, there's no need to explain exactly how you came to work for Company A each time you took a contractual position there. Your job application is a different animal; on it you'll need to list each "employer" separately as you have done above.

Keep your resume free of unnecessary complication. Try something like this:

2004 - 2008, Desktop Support Specialist/Technician (contractual), Company A, Boston, MA

• Wrote clear, detailed work and resolution information in the Remedy Ticketing System, which provided Help Desk and DSS Department technicians with invaluable solutions to problems and enabled management to easily track asset inventory type, brand, model, serial number, and location.
• Authored several technical documents including checklists, which improved consistency between technicians and reduced hardware and software configuration and installation errors.
• Trained and mentored less experienced technicians and interns by providing on the spot training, tips and troubleshooting strategies.
  

This presentation looks quick and easy to read, is perfectly truthful, and is very impressive. Good luck with your job search!
