Meet the Founders

Carlton Washington and Deniz Duygulu

South Florida is home to the world’s best in food, music, beaches… and beautiful people. It’s no secret that youth and vitality are top dogs here when men and women long into their 40s are batting the avenue alongside contemporaries in their 20s.

Search analytics show terms like “Anti-aging supplements” and “latest in Anti-aging research” to rank 7 times higher in the tri-county than in other metropolitan areas, so it’s unsurprising that the industry’s best in age sustenance was born right here in Boca Raton. In 2014, Carlton Washington—looking to compete in a bodybuilding competition—searched and found renowned personal trainer Deniz Duygulu.

The two struck a quick friendship, and the regimen turned to conversation about an evident void in the industry: Conventional medicine was lacking when it came to men and women like Deniz and Carlton, who fought to be the best, healthiest versions of themselves. No matter their age.

And what services were available were not under one roof. Patients went to one place to get their blood drawn, another for supplements, and yet another for hormone replacement.

So they filled the void. There would be a new kind of practice: a one-stop-shop vitality center dedicated to Anti-aging medicine.

The first 4Ever Young center opened in Boca Raton in 2014. It was a lesson in preventative health care, where a roster of industry experts implemented proactive—rather than reactive—treatment.

Instead of only treating symptoms, 4Ever Young introduced a comprehensive evaluation process: an unparalleled, thorough blood panel that works to customize patient profiles and resulting care, further supported by cutting-edge science.

Patients noticed the difference.

“I am a personal trainer and fitness competitor who is very precise with my nutrition and training. For 9 months I fought a battle with my hormones. I went to 4Ever Young, they did an entire blood panel on me to find where my imbalances were. I never knew as a woman testosterone was so important. Well they gave me the pellets and 3 months later I feel amazing and almost completely back to myself!!”

“One thing that I’m always impressed about my visits to 4Ever Young is the high level of patient wellness and health before starting any of their programs under the supervision of their medical director…I got my quarterly blood panel done and my basic medical vitals were also checked to make sure I’m in good health.”

The model is divided into two programs: Look Your Best and Feel Your Best.

A range of Look Your Best cosmetic services provides solutions to concerns regarding visible signs of aging, something a lifetime in paradise can exacerbate. Blotchy skin, happy wrinkles, early gravity… 4Ever Young offers the industry’s best in:


  • Botox
  • Dysport
  • Juvederm
  • Restylane
  • Sclerotherapy
  • Sculptra
  • Kybella

Facial Care

  • Custom Facials
  • Dermaplaning
  • SkinPen Microneedling
  • Chemical Peels
  • Hyrdafacial MD Elite

Shaping and Body Care (only available at limited locations)

  • Coolsculpting

But we know that appearance is just a surface indicator of wellness. And in here lies Deniz’s sweet spot: finding the answers to age-related hormone changes and nutrient deficiencies you can’t find or articulate with the naked eye. Energy loss, declines in physical, mental, sexual health, stubborn weight…imbalance in overall wellness affect more than most.

4Ever Young’s Feel Your Best program is built for this, with services like vitamin injections and bioidentical hormone replacement therapies, all developed with your blood panel and packaged in a customized patient profile.

The goal is transformation, to rewind your clock and help you live your best life at any age. And Deniz has walked the walk of transformation; Once an unathletic, skinny kid, Deniz got real with health and fitness, rewrote his trajectory, and became a recognized fitness professional.

To talk with Deniz about hormone imbalances and therapies is to talk with a man impassioned. He is a true believer in the power of a healthy lifestyle, and his own trials have awarded him expertise in nutrition, exercise, and proper supplementation. He’s a patient of bioidentical hormone replacement therapy and believes it is a crucial component of medical Anti-aging.

It was this holistic approach that bolstered Deniz’s enthusiasm for this project to help people look and feel their best. And he uses all of the 4Ever Young services himself and knows that Anti-aging practices have changed his life. He wanted to share the magic.

So after an overwhelmingly successful few years in business, and to the delight of a nation wanting to look and feel good with a comprehensive, customized plan, Deniz and Carlton decided to franchise.

The plan caught, piquing the interest of franchisees wanting a piece of the pie. 4Ever Young now has ten operating franchises and will see 20 more by the end of the year. New partners sign each week, all are mirroring the vibrant, community-involved energy of the 3 original corporate locations.

Like Carlton says, in an appearance on FranTastic Insights (hosted by FranServe nc.’s CEO Alesia Visconti):

“We thought it was just us (that noticed an industry void), but we’re getting in on the ground floor of both the growing wellness and aesthetics industries. The manufacturers themselves are pouring more and more into these services and into developing new demographics. We’re seeing new types of patients that we’ve never seen, 7.5 years in. It’s a market that nationwide hasn’t been penetrated, and we’re seeing these services becoming necessities. It’s not just a trend. Looking good and feeling good is like going to get your hair cut. Just one more stop—get your nails done, get your IV, make sure your hormones are good…the response is overwhelming.”
