about cdi




Commercial Divers International’s facilities are unmatched. At our brand new 2.8 acre facility, we have three 21,000 gallon tanks, each providing a controlled environment in which to train and practice projects. Additionally, we have a penetration tank to simulate penetration and confined space diving. The tanks have side-viewing windows so students can be observed at all times by instructors both in and outside the tank. Our hyperbaric chamber provides the chance for students to experience and learn first hand, crucial, potentially lifesaving, chamber operations.


CDI owns their own 37 acre lake, proudly named Lake CDI located nine miles west of our flagship campus where open water diving operations are conducted in “real life” working conditions. Limited student housing and plenty of RV and trailer parking is available at Lake CDI and we host luncheons and BBQ’s.

We offer a surface-supplied helmet diving experience to anyone considering our program, or to anyone who meets the physical requirements who want to experience the thrill of an underwater, full helmet, surface-supplied dive. Our equipment is state-of-the-art and meticulously maintained. Our students dive with the best helmets in the industry (Kirby-Morgan, Desco, Gorski). You’ll become an expert on helmet operation and maintenance well before your program concludes. You will be trained on and develop proficiency with the same equipment you will encounter on the job.

There is, of course, a whole lot more to the job than getting wet. You’re going to be using any number of hand and power tools down there. CDI will teach you the skills you need to safely operate drills, jackhammers, saws, impact wrenches, torches, and welding equipment in the underwater, industrial work environment.

Richard and Gina Phillips ,after over 18 years owning and operating a Marine Construction and Commercial Diving company, discovered the task of hiring and assembling a skilled and capable commercial dive teams to fulfill the varying requirements of projects across the country had become more and more challenging through the years, with less than 10 commercial diving schools in the USA to provide individuals with the education and intense training required for success in this profession. The hiring challenges inspired the idea to organize a school and implement a comprehensive program built with the needs of the industry’s changing environment in mind. The objective was to produce relevant elite professionals trained and educated by highly experienced industry experts to improve the preparation of the next generation of commercial divers.

The complete commercial diving training program was developed after collaboration with many professionals in the industry and ultimately resulted in a partnership with USN Chief Mr. Donald Moore and seasoned professional commercial diver Mr. Mark Plowman.

CDI is proud to have been the First Commercial Diving School to successfully completed the ADCI audit by demonstrating satisfactory compliance with the ADCI consensus standards for Commercial Diving and Underwater Operations.
