Doylene "DeeDee" Knapper, a registered nurse and advocate for noninvasive aesthetic care, is the owner of Radianté Spa Nashville, a female-owned medical spa in Nashville, TN. Raised on a Robertson County farm as the eldest of five siblings and numerous foster children, she credits her upbringing for instilling a strong work ethic and commitment to the community. DeeDee, married for 18 years to Charles Knapper, balances a bustling family life with six children, 11 grandchildren, one great-grandchild, and a chocolate lab. Her mission centers on empowering clients through safe, affordable alternatives to surgeries and injectables, emphasizing natural rejuvenation and body confidence.
With 46 years as a registered nurse, including 39 specializing in labor and delivery at Nashville hospitals and birthing centers, DeeDee assisted roughly 10,000 families during childbirth. A major knee injury halted her clinical career in 2019, prompting her to pivot to medical aesthetics. That year, she co-founded Your Best Body Today Nashville (YBBT Nashville), a licensed med spa offering nonsurgical fat reduction and HIFU facelifts. Despite COVID-19 shutdowns three months later, her tenacity sustained the business through widespread closures. In 2022, she rebranded as Radianté Spa Nashville, relocating in 2023 to Berry Hill where she personally renovated the space into a luxury wellness hub featuring collaborative health and beauty services.
DeeDee specializes in nonsurgical body sculpting, skin tightening, fat reduction, and cellulite correction, leveraging technologies that activate the body's natural healing processes. Her spa provides inclusive, judgment-free care, prioritizing safety and accessibility across socioeconomic backgrounds. A hands-on leader, she designed Radianté's elegant interiors — complete with custom oak countertops and arches — to reflect her belief that confidence stems from feeling valued. The spa now hosts wellness partners in massage, mental health, aesthetics, and styling, embodying DeeDee's vision of holistic, affordable self-care. "Confidence is beautiful," she says. "Everyone deserves to feel empowered."
Great quality and value! Been going repeatedly over the last year to receive laser facials and the results have been great! DeeDee is amazing and is an expert in this field! She will make sure you get the best service for the results you're looking for!
Bare with me since this is a lot. I dont like leaving personal reviews, but after thinking about it, this information may help someone who was/is in my situation.I had fat grafting done as an option to avoid putting fillers in my face. If you dont know what that is, its when they liposuction your fat and inject it back into your face, and around month 2 of my recovery, I started to notice lumps from the donor site on my abdomen. As the months passed, I started to panic because no matter how much I rubbed the area, or wore compression garments, the lumps weren't going away. I had to gain weight just to have the procedure in the first place, and I had always had a six pack from being athletic. Seeing what my surgeon had done to me (with no solution offered by her to fix the lumps mind you!!!) had me feeling extremely upset with my physical appearance. After months of searching for a non surgical solution, I found Dede and her Sentient tool. I bought a package of 3 treatments, just to see if it would work. Its been a month after my first treatment and almost ALL of the lumps are gone! I just had my second treatment today, and I'm almost positive my stomach will be fixed by the 3rd treatment. Couldn't be more thankful to have found something that worked.
The procedures i have had done has almost completely eliminated my muscles spasms/cramps. Highly recommend this spa. Very attentive and listens to your needs.
DeeDee is amazing and so sweet. She is very knowledgeable. I went in for laser treatment on my arm pit. I had a boil/cyst that I had for 4 months and it finally drained but it left an open wound and was still oozing from time to time. It was so red and inflamed and still painful. She did the laser treatment under my arm and at the end of the session it was less red and even smaller than when I went in. 2 days later, shrank even more. I am so happy this is finally healing after months of a wound and it just being uncomfortable and honestly a little embarrassing. There is such power in laser treatment. I will be continuing other treatments with DeeDee and will recommend her to everyone! Her spa is very well decorated and peaceful. Just what you need to have a relaxing time!
OMG this place is now my holy grail.I’m going into my third appointment, and after just one laser treatment on my face, I saw a real difference.I’ve spent years (and thousands) trying different clinics and products, especially as someone with melanated skin—and it’s not easy finding treatments that actually work and are done right.This is the first place where:The treatment worksShe clearly knows what she’s doingI feel comfortable coming backThat combination is soo rare.I’m already planning to treat other areas because I trust the process here. Everything is explained clearly, and I never feel rushed.Not gatekeeping this—I know how hard it is to find something that works. If you’ve been searching, this is 100% worth it.Finally found my clinic.
