Patient Testimonials

Successful Liposuction

“I had liposuction done on my lower abdomen and flanks and everything went really well. I think Dr. Duncan and her staff are incredible. Everyone is incredibly nice and welcoming, and they were patient with all of my questions. My body looks as well as it should 6 weeks after surgery and I can't wait to see the final results in several months. I would definitely choose her again.”

NEO resolving chronic back pain

“I had chronic back pain before I started EmSculpt Neo treatment. I could never bend over without having a lot of pain. Now, even three months after treatment, I can move freely without issue! I can lie on the floor or the couch, do workouts, and stand for long periods of time without any back issues whatsoever. I highly recommend this treatment.”

I feel beautiful and look natural

“I want to thank Dr. Duncan and PSA for the incredible transformation they were able to achieve with my body. Having children and age had made me feel disfigured and unfeminine. I researched for a long time, many different surgeons, and even considered going out of the country. I am so glad I went with Dr. Duncan and PSA. I feel beautiful and look natural.

I immediately felt comfortable

“Most of my life, I was happy with my C-cup breast size. But after having four children and turning 41, my breasts were small and sagging and barely an A-cup! I made a consultation appointment with Dr. Duncan because of her 20+ years of experience, and at my initial consultation, I immediately felt comfortable.

Most of my life, I was happy with my C-cup breast size. But after having four children and turning 41, my breasts were small and sagging and barely an A-cup! I made a consultation appointment with Dr. Duncan because of her 20+ years of experience, and at my initial consultation, I immediately felt comfortable. Dr. Duncan listened to me and took the time to answer all of my questions. I consulted with two other plastic surgeons, who both recommended an implant size larger than that of Dr. Duncan. I would have been very unhappy with breasts larger than I have now!! I definitely made the right choice in selecting Dr. Duncan for my breast augmentation.

I can’t say enough about Dr. Duncan and her staff! I was made to feel comfortable every step of the way, and I genuinely had a great time through the whole process, even during surgery. Diane Duncan exudes confidence in her craft, and it is displayed in her work, experience, and reputation worldwide. I have never had any type of surgery, and Dr. Duncan, the nurses, and staff members were wonderful on the day of surgery (and throughout the process) and set me completely at ease. I am VERY pleased with my experience and would recommend Dr. Duncan to anyone interested in Plastic Surgery.

I am renewed, whole again, and complete

“Only after this wonderful surgery have I come to realize what you have given back to me, almost as a by-product of the surgical procedures. Joy, pure and simple joy!

Dr. Duncan achieved a very natural look for my body

“From the beginning to the end, my experience with Dr. Duncan and staff was over-the-top exceptional. Everyone was helpful, knowledgeable, and very friendly. I feel the work I had done was perfect and that Dr. Duncan achieved a very natural look for my body. I highly recommend PSA and will be visiting them again in the near future for other procedures.”

Everything went smoothly and healed up great

“I had a rhinoplasty with Dr. Duncan about a month and a half ago. Everything went smoothly and healed up great! I had to get a septoplasty as well with a different doctor, and she was so great with accommodating for that. Little to no bruising anywhere, just a scar where my nose was opened, but with scar cream it is fading slowly. I love my new nose!”
