What Clients are Saying

“From the very first meeting, S2o Design and Engineering (now Calibre-S2o) and Scott Shipley’s design and leadership were instrumental in not only providing a world class recreation and competitive venue, but also providing the City of Montgomery with a new destination identity. Scott’s excellence in engineering and passion for paddling and outdoor sports have truly made Montgomery Whitewater a unique destination.”

Jeffrey Gustin, Montgomery Whitewater

“Calibre is great to work with! Scott Shipley and Riley Adams have been instrumental in helping our firm develop a new and exciting design for the riverfront in Columbus, Indiana. They are true team players and very dependable in responding to questions and meeting project deadlines. I highly recommend them!”

Randy Royer, Hitchcock Design Group

“Without the Calibre-S2o team, we wouldn’t have successfully completed our project in Cunovo, due to all the specifics and unique characteristics of the venue. We appreciated the team’s friendly and kind attitude. We look forward to working with them again on any whitewater project in Slovakia”
