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."
I have been going here a few months for intimate area skin lightening and love it. I can’t recommend this place enough. Doylene is amazing and so thorough with what she does and how she explains things. I’m happy to have found her and have had wonderful results (including a bonus side effect of skin rejuvenation 😍).
Excelente servició, son muy amables y profesionales an ayudado a recuperar mi autoestima ya que soy mamá y tenía mucha grasa y elasticidad y gracias a ellos acabé con ese problema si eres una persona como yo que habla español cuentan con una persona que habla español 🥰
Excellent service! If I could give more than 5 star, would do it! I have been going to a different clinic for hair removal with minimal results with 11 sessions. I decided to switch to Radiante, and has been the best decision I made. I am undergoing laser hair removal of private areas and with 2 sessions alone, I saw great improvement including reduction of hyperpigmentation. Deedee is amazing! She never fails to explain everything. Would recommend them 100%.
It checks all the boxes for my wife and me, Excellent location, easy access and parking. We have been customers as a couple for years and it gets better all the time with new face and body treatments. As a Men I can say that face hair removal laser treatment are Great as I can keep my beard line intact and I barely have to shave now also I’m very happy with skin tags removed from my neck that kept me from wearing jewelry. Deedee always have treated us very professionally and the same time like part of the family reason why we travel from Clarksville to see her every time.
I have been dealing with melasma for years and Deedee have made a great improvement in Clearing my face that nobody else even Doctors in dermatology haven’t done. Great price and service in a beautiful environment. I’m very happy with the results and will recommend to anyone who has been dealing with melasma.
