2025-12-21I booked an appointment today with Lisa at 5:15p (my first time here) because she got lots of good reviews. She took care of me very well and was very careful. She didn't ignore me & do whatever she wants, but she asked questions for whatever reasons and it shows that she does care. I was a bit skeptical at first since I've never been there and I didn't want the tech/or her to rush my pedicure, but it turned out perfect! Was so relaxing. She added 2 mins extra massage for me as well. I got gel funny bunny on my toes, and I know that color is a bit harder to polish but the color turned out perfect, wasn't messy, looks even and everything :D Def recommend!

2024-08-10Paul and Lisa are wonderful to work with, Paul has been doing my manicure since I moved here in March. I now have my own nails no tips. Which goes beyond any place I have ever gone. Lisa does an amazing job on my pedicure. I look forward to seeing them each time. Wonderful business.

2025-10-07I got my nails done last Wednesday and pretty much all of the acrylics have popped off. I have never had acrylics do that before that fast. Not even glue on nails pop off that fast or easily. Quite disappointing when I paid $70+ (including tip).
