5 out of 5 stars Mommy Makeover

37 Fixing Years of Living with Botched Lipo/Downsizing Implants/Mommy Makeover - Newport Beach, CA

After years of deliberating over having such a major surgery, I finally bit the bullet on Oct. 3, 2016. I wish I had kept a day to day diary, but I had no idea how much I would be willing to share online. Now that I am 12 weeks po, I feel I have a valid opinion on whether or not I believe it was all worth it. A little on my background: I am a 37 yo mother of two teens. I'm no stranger...

Lower Body Lift I've Been Dreaming of for Years! - Newport Beach, CA

Dr. Agha is extremely talented and a true artist. He's very kind, but I might have liked a little more contact with him for reassurance. Instead, I had a lot of contact with his office staff which was okay, too. They were very nice.

5 out of 5 stars Body Lift


As a former model who's found out the hard way that not all surgeons are created equal, I asked some of my famous friends who they like & I also asked some of my doctor/nurse friends whose work they like & who they have seen consistently fix the most difficult cases. This is how I found Dr Agha. He's a real diamond in the rough. No surgeon can give you a better result than he does. He...

5 out of 5 stars Forehead Reduction

Great experience!

Dr. Agha and his staff are great. They made me feel so welcomed the first day I came and Dr. Agha and Shireen were able to answer all my questions from the procedure, which was a forehead reduction, to the financial payments. The office is very clean and the staff team is organized. I love the results of my procedure and feel a lot more confident with myself. Roma, the medical assistant, is...

Multiple Procedures After 115 Lb Weight Loss. INCREDIBLE Results by Dr. Agha! - Corona Del Mar, CA

After losing 115 pounds (through Weight Watchers), I was left with excess skin that kept me from completely feeling comfortable with my body. Luckily, I have a loving and supportive husband who didn't think I needed surgery, but was totally empathetic to my feelings about the extra skin. We met with three different plastic surgeons before meeting Dr. Agha - but once we did, we never looked...

27 Years Old Athletic - Corona Del Mar, CA

I've gone to LaserAway for CoolSculpting and one other facility and I will say that I prefer The Aesthetic Center to any other facility. Not only do I love the staff, but they provide you with extra blankets and pillows and they have Wifi along with Netflix and Cable TV. LaserAway did not provide blankets or Netflix, which made the procedure time seem longer and I was very uncomfortable. ...

Dr. Agha is very knowledgeable with a womens body especially after a weightloss. I chose Dr. Agha because I felt comfortable with him and he was keen to answer all of my questions.
