Dear Staalsen,

I would like to thank your organization for the way in which our construction project at 2000 York Road, Oakbrook, Illinois was handled.

A special thanks to Randy Olsen; his friendly manner and technical knowledge are an asset to your company and to anyone who comes in contact with him. Rick St. Marie as foreman, did an outstanding job coordinating all the sub-contractors and bringing the project in on schedule.

The materials and workmanship by your company and your sub-contractors was of the highest quality.

Please do not hesitate to add our Corporations’s name to your list of satisfied clients.

Thanking you again, I remain,

Sincerely,

Robert W. Geitz
