First of all, Dr. Leong is not only "Doctor" intelligent but he's also relatable and down to earth. On that note itself, I give him 5 stars. I had my under eyes done. I researched and found him to be the best at this in Pittsburgh. I got an appointment quickly. My wait was less than 15 min once I arrived. His staff were kind, asked questions about me personally, and treated me like I had been there a dozen times before. The procedure was painless. I had minimal swelling. And the results were exactly what I was hoping for. I had a lot of hollowness and dark circles from aging, genetics, and stress. He said I would look natural after and he was right. Aside from the first day swelling, you can't tell I had fillers. I look refreshed. Listen, full transparency, This isn't my first cosmetic procedure. Ive been to other PS's. I can't say all my doctors are like Dr. Leong. He's def my new fav. If you need any work done on your face, he's your guy.
