To Whom It May Concern:
I have completed two jobs with Sierra Security and in both instances found their work professional and performed in a timely manner. Their operations are clean and professional. The staff is helpful and their performance is of an excellent standard.
I can wholeheartedly recommend them for any job that you may want to hire them for.
I am available to speak with personally should you have any questions.
Sincerely,
CEO William H
