Letter from the President

My goal creating Ascent in 1997 was to create the preeminent process design firm serving the refining and chemical industries filling a niche not met by competing firms.

Our motto is simple, “Do what is best for the client”. We honestly believe doing our best for you, helps us both be successful in the long term. The vast majority of our business is repeat business and referrals. You have my commitment we will do our best to meet and exceed your needs as we have for our other clients.

Our core competency is the right project for our clients, and not the project with the most engineering man-hours to keep the detailed engineering firm billable. Our corporate niche is up front project identification, development, and process engineering through detailed Process Design Packages. We believe project development is best handled by small, highly skilled teams independent of the rigid management structure required by large engineering firms. We identify, develop, and process engineer with small groups to a level of detail so the project can be turned over to a larger contractor and executed without engineering recycle and waste. This is our focus, and we think we are one of the few, the largest, and the best at maximizing client value at the crucial process development and design project phases which have the largest impact on project costs and success.
