It`s like hiring an Attorney for your filing

I wish I would have used them for my original license, I would be further ahead in my NC tonnage. After being confused about the requirements for an upgrade, both tonnage and GL/Inland vs NC, I contacted Diamond Marine Services. They listened to what I was trying to do and guided me down the right path. They saved me money by pointing out that I didn`t need another drug screen, nor another physical. The Examiner assigned to my application kept returning my application and requesting information in order to qualify for the upgrade I applied for. Diamond Marine Services responded to the Examiner directly to clarify what I was applying for and pointed out the regulations that I met. After a few back and forth communications with the Examiner and their Supervisor I was issued the upgrades I applied for. Diamond Marine Services more than saved me the cost of their fees, and went to battle for me when there was an issue with the application. I will be using them again fo

I’m very impressed and thankful for all the help and guidance received from Sam, and his company! If I could give him 10 stars I would, but this thing only allows 5! He made the process as smoothly as possible, I received my oupv 6 pack license and was a breeze having the guidance and help to get through! Don’t go any other way, give them a call!!

10 stars if it would let me

Stop reading reviews and let these guys take care of you. Sam and his team will get you your license fast. He gets this stuff filled out right the first time and submitted with everything the coast guard needs. It will be a pain in the butt doing it yourself especially for the first time. Follow the portal submit what Sam asks for and it’s as simple as that. He will communicate with you every step of the way. Just sit back, give him what he asks for and let him work his magic and your little red book will be in your mailbox before you know it. Sam thanks for everything I really appreciate you! You’ll be hearing from me in 4.6 years 😁.

Extremely Thankful

I took some years off from the industry and my MMC was about to expire, Sam & company came through. Sam went above and beyond and help me upgrade to a license I didn`t know I qualified. I would recommend them to anyone looking to get a start or even a veteran in the trade. Best part was any question I had was answered same day and usually within 30mins. I will continue to use Diamond Marine in the future.
