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 🥰
LISTEN TO ME; if you have never tried the sound therapy bed just go ahead and call them!!! You won’t be disappointed!!! I was online searching for a spa that has sound therapy beds. I had no idea what an experience was coming to me!!! When my husband and I arrived we were immediately welcomed by Dee Dee and Shawn. They where a breathe of fresh air!! The sound therapy bed was just as I was expecting it to be; AMAZING!!! I love that they have it setup so that I can get my therapy AND red light at the same time. Dee Dee took time to answer all my questions and didn’t make me feel rushed!! I can officially say I have finally found my spa home!!! See y’all soon
Dee Dee was recommended by a friend and I got laser and CO2 treatments on a wound on my foot. She is extremely knowledgeable and very nice. She explained everything very thoroughly and the treatments were quick and painless. I’ve already seen an amazing improvement. I will be back for additional treatments including some dark places on my legs. I cannot recommend her services more highly!
I had a great experience and results here. Deedee and Tammy are so knowledgeable and friendly. I have seen some real improvement and tightening of my face and legs. Would highly recommended!
