"As always my experience was awesome! I wasn’t sure about having two crowns put on at the same time, but the process went smoothly and I was done in 90 minutes!"!

Laurie, R.D.H., Hygienist

Laurie wanted to be a hygienist since childhood. In fact, when she was just a pig-tailed grade schooler, she was already lining up her Cabbage Patch dolls for their “happy teeth cleaning” visits. She got her A.A. degree in Dental Hygiene from Lake Superior College in 2002. Immediately after graduating, Laurie started her dental hygiene career in the Twin Cities suburb of Chaska. After getting married in 2004, it only took her husband 2 years to convince her that Duluth is a much more fun place to live. They packed their bags, headed north, and Laurie began working in October 2006 where she’s been happily cleaning teeth ever since. When she’s not polishing pearly whites, odds are you’ll find Laurie at the cabin, sitting in a floatie reading her Nook, or taking a lazy spin around the lake in her kayak during the summer months. During the rest of the year, she enjoys spending time with her husband, Mat and their two labs, Gretta and Reese. She also loves to golf and is learning how to be an excellent gardener.
