She looked at the picture my daughter brought as an example of what she wanted, and Holly took a quick look , smiled and was reassuring that she had it under control and it was better than we ever would’ve imagined! All the staff are so kind so courteous so sweet so welcoming! The atmosphere is friendly. The salon is so clean and nicely decorated !! We found a new spot! Thank you everyone at HAPPIEST NAILS!!

Amy was amazing with my 8 yo. daughter and she’s incredibly talented in the art of nail decor. The prices are very fair and the ambiance is clean and pleasant. Best nail salon in north county imho.

Rose did a wonderful job. I asked her to remove my old nails (done by another nail salon) as I wanted to get back to my natural nails and grow them out again. She was patient and paid attention to every detail. I’ll definitely come back!
