Here’s What People Are Saying

“I have had the privilege working with the Rock Supremacy team since their beginning over 9 years ago. Rowan Anderegg has done a superb job building and leading the company. RS is very professional and responsive to the clients needs. RS has an excellent safety program and continually trains their personnel in rope access safety issues. RS is also innovative and thinks outside of the box, it has been my experience that if there is a problem, they consider it a challenge to figure it out and solve it.  Can’t is not in their dictionary. Clients like the timely and professional services that RS provides. I would not hesitate to hire RS again for a project or recommend them to one of my clients.”

Thank you for assisting us with the tunnel inspections for Idaho Transportation Department. Dave Wilks Sr. and Grady Serrao were wonderful – assisted with every aspect of the inspection and provided valuable insight on tunnel conditions for both the concrete lined and unlined tunnel segments. Both were actively engaged, helped the team provide a thorough tunnel inspection, and were a joy to work with.

I thanked Dave and Grady for having the Covid vaccine and I appreciate you all for being sensitive to and accommodating my health concerns. It was not expected and I am sincerely touched that you all went to that effort. Thank you.

As always, it was an absolute pleasure teaming with the Rock Supremacy on another tunnel inspection effort. It was a delightful way to closeout my career. Thank you.

We engaged Rock Supremacy for a very challenging cliffside project that involved the stabilization and reinforcement of a retaining wall which ultimately required a total of ten drilled horizontal rock anchors, multiple vertical stabilization pilings and encapsulation with concrete structural reinforcement.

Even though my residential project, as large as it was to me, was of a much smaller scale than the company often deals with, it approached the task with all of the consideration and professionalism I could hope for. Notably, they were not hesitant to take on a challenging terrain even with its limited access.

From the outset, Corey Muir was very engaged in the project and with finding workable solutions. He was eager to explore alternative options for accomplishing the goals and worked diligently with my engineering consultants to tweak the design for a practical, affordable solution. Throughout the planning process, he maintained excellent communications with myself and our structural engineers. Corey was careful to make sure, prior to our final agreement, that all details were fully understood.

The company began the project exactly when anticipated. The on-site crew, David, Nate and Jules proved to be the “A” team. They are very skilled and professional. I found them considerate, easy to interact with, and flexible with regard to change possibilities. The team showed careful concern for my property and all possible avoidance of collateral damage while completing a job that involved some very heavy equipment.  When the concrete supplier was unduly delayed, they took it in stride and made the best of the situation. The job was actually finished a little ahead of schedule.

Definitely a five star rating for this group, I would be happy to further discuss my experience with anyone contemplating the use of Rock Supremacy’s services.
