Premier Account Management
"When I started working on the granite account, I was completely lost. Kim [the Premier Account Manager] took the time to hold my hand through your website and answered my questions, iteration after iteration. I was assigned a very important project, that I would not have been able to complete if it was not for her and her dedication. She is an absolute value-add to Sonic and I truly appreciate her! If only I could get all the vendors that I work with to be as thorough, detailed and CARING as she is, my job would be so much easier. Thank you to whomever sent her our way, she is a great asset and I sincerely hope there are no plans to move her away from the Sonic Team…." - Sonic
