Great Pyrenees grooming recommendations?

Looking for a groomer for my GP. She’s an anxious dog and needs someone willing to take their time and be patient with her. She’s extremely sweet once she warms up. Really prefer someone with experience with these dogs and is used to their size and how to groom them properly. I don’t want my baby to get shaved up 🤣. I had good luck with the last one we found but really felt like we got taken advantage of in a couple ways.
