USCG License Renewal

I am on my 8th renewal for my USCG License and normally I would do all the paperwork myself but with all the changes of staff and paperwork I decided to reach out to Diamond Marine Services and now I am glad that I did because the people doing the paperwork at NMC are not really up to speed anymore like they use to be so I had a few set backs because they kept asking for more and more documents but Sam was able to Liaison for me and this sped up the process. I would highly recommend using this service for anything to do with any License. Sam replied back to me on every query that I had and saved me a lot of time and headache since I was overseas trying to do this. Thanks for your professionalism and it is nice to find a company so qualified and also has the License/Skill and Knowledge to get things done.

The class started right on time with the captain ready to go. We got onto the tug and quickly jumped right into learning about how the boat operated without a barge made up to it. We then went through several tasks to make up a barge and later operated with and without the barge made up. The captain was kind and helpful through every step of the process and the deck hand was a pleasure to work with. This was my first time ever being in the position to operate a tug and barge and I was nothing but comfortable and confident with the instructions given to me. Overall this is an amazing class and would recommend it to anyone looking to complete their endorsement requirements.

These folks get excited about the stuff that most of us dread. Needed a very quick turn around on a license renewal and they really delivered, and got me an upgrade that I wasn’t expecting. Friendly, personable, and definitely my first call next time I’m up for a renewal.


Excellent customer service

I called Sam about completing a TOAR and he took care of me and made it happen. Got to the boat and Ben was just an excellent teacher and made sure I knew his expectations and we made it happen. Thanks guys I really appreciate it!

If you need a TOAR, call Diamond. I was in a pinch and needed to get this done ASAP. I called them up on a Wednesday morning and was on a plane a few hours later, headed to Boston. My class was scheduled for the very next day, Thursday, in Boston Harbor. I have nothing but positive things to say about them. Extremely accommodating. The assessments were explained clearly and concisely and executed under expert tutelage and I had an email in my email box with the completed assessment form before I even got out of the Uber to the hotel. … which, by the way, was another amazing experience. They recommend the Mariner House and I second this recommendation.
All in all, extremely positive experience. Don’t hesitate to call Diamond if you need to get this done.
