Pam was wonderful to work with during the entire kitchen remodel. She communicated clearly and often, and she was very efficient. I really appreciated that she listened to what I wanted and offered her ideas also. It was clear that she had respect of the sub-contractors too; they responded to her promptly. The project flowed smoothly with Pam's work and her choreography of the sub contractors. She transformed my old 1958 kitchen to a beautiful new one. It's better than I imagined. I would definitely recommend her for any remodel project.
