What Our Clients Are Saying

“I want to personally tell you how much we enjoyed working with WildHeron and the rest of your employees on the well project at Table Mountain Ranch in Red Bluff. Everything went together extremely well because of your diligence and responsiveness. I definitely appreciate dealing with a company like yours. Thank you again. The well is a success, and our relationship is very very solid.”



“From start to finish, we have been impressed with the service we received from everyone at WildHeron Drilling. The crew was professional, courteous and knowledgeable. The real stand out, however, is Bryan. His depth of experience and knowledge in both drilling and top side work is evident in the quality of his work. Bryan takes pride in working hard and doing things the right way, and he encourages his co-workers to go the extra mile in every detail of the work, from building the well all the way down to cleaning up the site. We asked him lots of questions and he always patiently explained the process to us at each stage. It was such a comfort to know that our project would be completed to Bryan’s standards and to our satisfaction. We knew that Bryan wanted to do what was right for us, the customer. It is rare, even more so these days, to find such a reliable, conscientious, responsible, motivated and dedicated individual. You are very lucky to have Bryan representing your company out in the field.”



“Ray and WildHeron were great from start to finish. They helped us with the entire well design process and made the entire process easy and pain free. We’d highly recommend WildHeron to everyone!”
