  • Once again, the professional team at AMS continues to set the bar in preparation, coordination and execution of the necessary requirements to provide a safe & effective helicopter lift operation.

    All Erickson team members present for this event clearly recognized these efforts and commented to myself accordingly.

    It was a team effort, and I personally am very proud to be apart of this operation. 

    Best regards to all,

  • I just want to take a quick moment to commend your plumbing staff on the well-executed domestic water pump change out. I have never in my 30 years in the business seen a project go as smoothly and professionally as I have today. Your guys worked non-stop from 7am to make sure we were back on line with hot and cold water by 3pm when it was a scheduled shut down until 5pm.  I know that whatever the issue is her at the hotel Center, your plumbers as well as the two boss ladies Donna and Shannon get it done and make sure that our needs are met with priority. Thank you again for your professionalism and team work. BTW, Honorable mention to Frank for making sure the tank got done today and scoping this job two years ago. We love ya Frank, just not as much as everyone else, LOL!!
