Bock Technical 2558 East Big View Drive, Oro Valley, AZ 85755

"I've done my Tec40 class with James and will be starting Tec45 with him soon (and eventually CCR40). I heard great things about James prior to my first course and he did not dissapoint. He pushes you to be a safe and competent diver and makes sure you have a solid foundation to continue to build your experience off of. He is knowledgeable and goes beyond what's needed to make sure you have a thorough understanding of techniques and concepts. If you want to go the tec route, I wouldn't recommend anyone else. He has a passion for diving and safety I've rarely seen matched."

"James Bock is a phenomenal instructor; he lays down a foundation that will help you crossover into other sophisticated forms of diving like cave and rebreathers. He is incredibly knowledgeable and passionate about diving and wants the very best for his students. He will help you become your best."

"Technical Diving is serious business and you need the best instructor you can get. Call James. He ensures every skill is solid as we progress, taking much more time than the average tech instructor to be certain that we have mastered it. I didn't think I could tech dive. Lots of people didn't think I could tech dive. James taught me so well and thoroughly that I am now confident that I can hold my own with most anyone. I was doubtful and now I'm a raving fan! Another advantage of working with Bock Technical is that you gain a built-in community of highly trained divers that you can team up with for both local dives and bucket list trips. I strongly recommend that you do it the right way from the start and learn to tech dive with Bock Technical. And to all the women reading this - yes you should do it too! Why let the boys have all the fun?"

"James is a once in a lifetime instructor. There are not many instructors that are as dedicated and as knowledgeable about diving as James. The material is challenging, but James will take the time to walk you though it and in the end make you the best diver possible. It is my firm belief that I wouldn’t be where I am as a diver today without Bock Technical and James."

"I have learned so much in my tech classes with James! He brings a wealth of knowledge and experience to his teaching, and holds students to very high standards. His classroom sessions were engaging and useful, and although his in-water training was tough, I don't think my diving has ever improved so much over such a short period of time. James is a detail-oriented and passionate instructor who puts a ton of energy, effort, and preparation into his classes. I'm proud to be a Bock Technical diver and will be continuing my training with him. I highly recommend him to anyone interested in technical diving!"
