I've been going to Vicki at the Nail Studio for approx. 10 years and have never had a problem with any kind of nail disease. Her prices are inexpensive and she's FAST!
If you want a pedicure, they have the GREATEST massage chairs in town, and do a terrific pedicure too! 3 days out of the week they do pedicures for $17, rather than $20 the rest of the week.
