Dear Randy,

We just wanted to tell you how pleased we've been with your referral of Geordie Steilen of Design Master Building Systems. He's done a fantastic job with our remodel. He first added a playroom to our basement, and framed out a new bathroom and work-out room. We then moved up to the master bath, and he's successfully managed a slew of subcontractors to complete the entire project on time and within budget.

We've become good friends of Geordie's and enjoy his presence in our home as we continue working on the basement remodel since completing the master bath. We appreciate his approach to the work and handling of the various small problems which inevitably occur. He brings a welcomed experience and an enviable energy for the job.

So thank you so much for the referral. We'd happily refer him for further work for any of your clients.


Julie & Leif Linderman
