About our Founder:

Melanie Dingman is the Founder and Owner of Commercial & Industrial Diving Company LLC. (CIDCO).

Growing up in Covington, Louisiana, owner and founder Melanie Dingman grew up around Commercial Diving and always a large group of Divers at the dinner table with her father.

With the tutelage of her father (Mr. Scott Dingman) an industry recognized Saturation Diver with over 35 years of offshore diving experience Melanie gained a great passion for the diving world in general and the underwater environment in total.

Under the guidance of her father (Mr. Scott Dingman) which has been the CEO of multiple Offshore Subsea Service Companies she developed a true entrepreneur spirit.

Melanie understood to attain a leadership position in any industry that she would need a thorough and comprehensive education and to achieve this she attended Nicholls State University, Thibodaux Louisiana and graduated Magna Cum Laude with a Bachelor’s Degree of Science and a Minor in Business Administration.

Following in her “father’s” footsteps she has dove feet first into the Diving Industry as a “Best in Class” Woman Owned Small Business.

Even today you may find Melanie enjoying herself on one of the many Bayous in Southern Louisiana near you!
