Tom Broderick

Scott is well organized and can recognize an issue and solve it. Scott also can manage a team of people to the same, only on a larger scale. I would recommend Scott as he has proven he can get the job done and achieve desired results.


Colin Yoshiyama

I worked closely with Scott Ruppel on the Cathedral Basilica of Our Lady of Peace Renewal Project. Over the course of 5 years, Scott headed the Parish Planning and Building Committee. Scott’s leadership and expertise in construction guided a diverse group of church members, architects, engineers, specialty mainland consultants, and contractors thru the complex process of planning the $15 million historical renovation. The results of his efforts were a permitted set of plans, a 2-year phasing schedule allowing the church to operate during construction, and the completion of critical structural repair work. It has been a pleasure working with Scott on this challenging project.


Steve Langham

Consummate professional. Exceptionally knowledgeable from both a technical and commercial perspective. As a seasoned construction executive, Scott kept our project well managed, on schedule and within budget directing significant staff and a host of specialty sub-contractors.


Mary Browne, CSP

Scott is organized, methodical in everything he does and a great resource. His knowledge, people skills and experience make him a great asset and a pleasure to work with.

Successful projects start long before design. Our core belief is the early definition of scope, timeline, and project budget drive success, so much so these key elements are represented in the first circle of our logo. Most projects fail when one or more of these key elements are poorly defined. To avoid this problem, connect with us today so we can help.
