Dear Sir/Madam:

I am writing to express my appreciation of the excellent services provided by two of your staffs, Mr. Joshua Craig and Mr. Ryan Swanson. Both Joshua and Ryan are skilled technicians with pleasant personality: friendly and polite. Although this is a routine home alarm system installation, the thoroughness of explaining the process and completeness of checking the work done speak for their dedication toward full customer satisfaction.
