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.

Education and Training

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.

Specialties and Expertise

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 went in for a consultation for body contouring. I had plastic surgery recently and was looking to refine the results further. From the moment I walked in, the atmosphere was welcoming and relaxing. I met the owner, Deedee, who was lovely and knowledgeable. Dede put together a plan to meet my goals, which we’ll pursue over the next few months. We ended up doing a laser treatment on a wound I had on my incision from my previous surgery, which has greatly sped up the healing process. I look forward to the coming results as we start the body contouring treatments. I had an incredible experience at Radianté Spa! I highly recommend them to anyone looking for high-quality treatments and exceptional service.

I have been going for the past month for cellulite removal and I have already seen amazing results! The staff are so friendly and really help walk you through the process and make sure you understand exactly how it works. I absolutely recommend to anyone looking for cellulite treatment. It is very painless and there’s no downtime at all.

I absolutely love this place! Doylene is incredibly thorough and takes the time to explain everything while providing top-notch service. I’ve tried both the Sculpt and Neo laser treatments, and I couldn’t be happier with the results. As someone who has visited multiple aesthetics providers in the Nashville area, I highly recommend them to anyone looking for effective treatments. I’ll be a regular client from now on!

I can’t recommend Deedee for your skin and body concerns enough! She is extremely knowledgeable and skilled at her practice!! she listens and actually hears you and is very thorough in treating your concerns! She explains everything so you can understand the process and what to expect! I have been getting the neo elite laser on my face and neck and I am blown away by the results! I was getting Botox every year and becoming unhappy with the results and decided to try something different. There is no comparison! Neo elite laser is FAR superior to neurotoxins. My skin is tighter, plumper, and the sun damage is fading dramatically! Also no weird unnatural looking expression lines around my nose that Botox was giving me ! My nasal labial folds are plumping and way softer already! I’ve only had two sessions and the results build over time so I’m excited to see my results in long run ! I can’t recommend Deedee and the neo elite laser enough!

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!
