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.

License Renewal and Credentialing help

Can’t say enough good things here! The folks at DMS were a huge help in my recent license renewal. Sam helped me navigate the complex rules to make sure I recieved my new MMC on time and more importantly without any holdups from the NMC due to lack of or incorrect information from my end. An absolute pleasure and would highly recommend their service to any Mariner looking to submit for any type of paperwork with the NMC and USCG. Thanks guys!

The class was very informative and pretty fun. Captain Birk is very patient and a wealth of information. The tug is very maneuverable and offers a good learning platform. Sam is quick to answer any questions from email or phone and the logistics getting to and from the class is great as well. Would recommend to anyone. Thanks!
