i personally have not gone to nana, but i have several reason why i have chosen got to go there
1. they have a lot of mixed reviews
2. there have been multiple instances of scheduling issues. one girl was supposed to have 2 surgeries in 1 day, but they tried to do too many surgeries in a day and ended up making her split her surgeries across multiple days. similar things have happened to others too
3. their prices are pretty high compared to other clinics. for the same price, you can go to a smaller clinic that specializes in what you're looking for
4. too many botched cases and unhappy clients. plus, in many beforre & after pics, the before is a barefaced person in a neutral position; the after is the same person with makeup, good lighting, and sometimes with a filter.
these are just my personal reasons for not going to nana. if those aren't a deal breaker for you or if you still like the doctor, then you should go!
