Dr. Diane Duncan brings regenerative innovation to traditional aesthetics.
—Heather, PSA Patient
5 star ratingPatients consistently love their results: natural, balanced, and beautifully tailored to their aesthetic vision. Delivered through a thoughtful, supportive experience blending artistry, innovation, and genuine care.

Dr. Duncan opened her Fort Collins practice as a board-certified plastic surgeon determined to make a meaningful difference for people who felt unseen or “not enough” after life changed their bodies. She built her practice on the belief that no one should feel stuck with features that don’t match the person they really are.

She refused to focus on just one approach. Instead, she trained in minimally invasive treatments, full surgical corrections, and everything in between. Patients get options that fit their needs, comfort level, and goals — from small, low-downtime tweaks to life-changing procedures that can improve daily life for years to come.

Dr. Duncan’s work is guided by one rule: timeless results beat trends every time. She avoids shortcuts and “latest hype” treatments that fade quickly or look obvious. Her patients want to look like themselves — only better, more confident, and comfortable. Safety, taste, and longevity always come first.

Recognizing that surgery alone can’t fix everything aging changes, she added regenerative techniques like fat transfer and tissue restoration. By combining surgery with biologic therapies, she helps patients heal at the source, improve skin quality, and see results that look naturally renewed — not just pulled tight or temporarily masked.

Beyond the operating room, she’s a teacher, researcher, and mentor. Dr. Duncan speaks at international meetings, publishes studies, edits journals, and sits on scientific boards. She shares her work so patients benefit directly from the newest, proven ideas in regenerative and aesthetic medicine — not outdated or copycat techniques.

Today, Dr. Diane Duncan brings over 30 years of surgical experience and global recognition for advancing aesthetic medicine. She teaches surgeons worldwide, serves on editorial boards, publishes FDA-level clinical research, and develops minimally invasive techniques that reduce recovery time. She’s been honored as one of America’s Top Surgeons and named a Castle Connolly Top Doctor.
















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 kept coming back to Dr. Duncan’s website because the photos of her work reflect my desire to look like myself after surgery rather than skanky with huge balloons on my chest. I am so glad I went with Dr. Duncan and PSA. I feel beautiful and look natural. She is a true artist. Thank you for giving me my femininity back.
Please accept my sincere gratitude for the excellent medical care I received from you and your staff. Your patience and understanding regarding my many inquiries were handled in a very professional manner. Your staff was especially courteous, prompt and caring. Thank you for being the greatest Doctor I have ever met in a long, long time.
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! I am renewed, whole again and complete. Astonishing discoveries, for someone whose expectations were so very limited. Thank you for being a part of the most positive experience of my life. I hear the scientist speak as I listen to your words. I see the artist’s work as I glance at my face. Thank you.
From the beginning to 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.
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. Diane Duncan exudes confidence in her craft and it is displayed in her work, experience, and reputation. 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.
