To whom it may concern,

I have worked with Geordie Steilen of Design Master Building Systems the past 3 years and have been very pleased. I would highly recommend Geordie to someone wanting a high level of commitment and professionalism to any project. Geordie takes a high degree of ownership in a project. He cares about the project as if it were his own. Geordie is very considerate of the owners needs; he worked under considerable pressure to keep things clean, quiet and orderly as we worked in a business that was still open during construction; both the Clock Tower Inn and Stella's Kitchen and Bakery. I have seen Geordie go above and beyond the call of duty to accommodate our business hours and operations.

Due the fact that my project is a remodel on an old building, numerous issues arose and Geordie is a natural problem solver and not afraid to make and stand by a decision. He accommodated me as I experienced issue after issue with the city and was very productive and got things done in accordance to their requirements and was always considerate of my costs and expenses. He has an amazing willingness to learn and a flexibility to new ideas and processes.

One of the most important things I would like to point out about Geordie is that he is exceptionally neat and clean. He is always aware of the messes that are made under construction and maintains a clean site throughout the day and sees that his crews clean up at the end of each work day. He believes like I, that a clean site is a productive site. I cannot express enough how much I appreciate his cleanliness, how he holds his crew accountable and how he cares about my property.

I am extremely pleased with his concern in regard to my expenses. We have developed an excellent relationship as Geordie is always accountable to me about the progress of the project and the expenses that incur. He is good about discussing the best possible scenarios and finding the most cost effective solutions. I appreciate his accountability and honesty.

We not only work together, but I also consider him a good friend and enjoy his company from time to time outside of work.
