Our Facility

In January of 2001, we purchased our own building and began extensive reconstruction.

Constructed in the 1950’s, this 11,000 square foot retail/office building was reduced to 30% of its original structure and was rebuilt it as it appears today. We designed the interior to have an open office work environment that would foster teamwork, which is essential to how we operate.

Of course, we did all of our own space planning, design, construction documents and project management. As luck would have it, that just happens to be our area of expertise!
