Dear Gary,

Christina and I would like to take this moment to convey our satisfaction with Tri-State Window Factory
and the Tri-State Window Factory staff. Carlos B., in particular, we found to be very skillful and
professional. In addition to Carlos\' mastery of his craft, we found him to be a good listener and willing
to work with us on some important technical issues. Moreover, he and his crew were respectful,
efficient and clean. Carlos\' skills as a fine craftsman and supervisor are clearly a major asset for a
company such as yours. We hope Tri-State Window Factory appreciates that.

Because we found you, your service staff and mechanics to be top-flight in every way, we would
recommend Tri-State Window Factory, without hesitation to our friends, neighbors and all who inquire
about you products.

Thank you very much for a job well done!

Best regards,
Gene D.
