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."
Dede was extremely kind and informative at my appointment! I got the sentient sculpt for cellulite and the aerolase laser for redness on my arms due to keratosis pilaris. This is the only treatment that has ever helped the redness, and I noticed improvement after 1 session. I will be a long time client here!
I love Radianté I’m so happy I found this place! Ive done some sculpting, a hifu face lift, and some laser treatments and the results truly speak for themselves. Here’s proof! I plan to leave another review once I’m done with my laser treatments 😌
Radianté Spa is 5 stars all the way. A beautiful, conveniently located place in the heart of Berry Hill. Dee Dee ( the owner) makes you feel comfortable the minute you enter the spa. She goes over exactly what she will be doing during your service and is happy to answer any questions you may have. I had a bit of an “emergency” . I developed a big cyst along with a few other sebaceous cyst on my chin. It was a bit sore and painful. She did laser it and in a matter of hours it had drastically gone down . Four days later she did a second treatment and results were even more amazing. No more cyst ! I have been using the Epicuris Skin care everyday since my treatment. It is really amazing. I am one SATISFIED client!
Had a membership at another med spa receiving monthly laser facials. Was happy with those results but I wanted to try the Aerolase laser facials to compare. It’s only been a few days since my first one but it is hands down a significantly more effective result than the competition! Deedee is awesome and extremely knowledgeable. The Epicutis skincare is amazing and will be making that my new routine for skincare. Thanks Deedee!
All around amazing from the comfortable setting to the highly educated staff ( Deedee & Tammy ) they explain everything so great and ways where you will understand and then they do wonderful work that continues to make my skin better by the day. Let’s just say I wouldn’t go any other place!
