Linda's Beauty Nails in South Windsor is my suggestion. I've been going there for a few years now and I've seen all types of people in there, including trans people. I, myself, am not trans but I have definitely had negative experiences in places because of how I look (colored hair, tattoos, piercings, wears all black). Linda and her team are nothing but welcoming and kind. I've never seen anyone there treat anyone with disrespect.

Also everyone there does amazing work it's very worth it!
