And based on his creativity and his experience, he was giving us additional ideas how to improve the apartment. He is very organized and always cleaned after each task. On top of that he made sure that all the work is documented and billed properly. We were lucky to get an amazing deal with Derek, and still the quality of the work was perfect and deserved twice of the total project cost. **★★★★★ — Maci Mascall, June 2016** > These shelves are incredible! Derek custom built these two shelves exactly how I described and they came out better than I could have anticipated. He was great to work with and very communicative during the project. The quality of his work is amazing and he exceeded all standards.
