From a young age, Tajana started her wellness journey through sports and medical treatments, which went hand in hand with preparation for highly demanding competitions. As Croatia’s first representative at the World Aerobic Championships, she was accustomed to discipline, competition, and, most importantly, teamwork and fair play. Having acquired these vital skills early on, she wasn’t afraid to start her own company at 22. As the founder of TT, Croatia’s first high-end “members-only club", Tajana combined medical treatments, challenging sports protocols, and relaxing spa programs—without even knowing the science behind it at the time. Today, epigenetic science validates that her early programs effectively reversed aging, optimised her clients' health, and boosted the performance of professional athletes at her club. 

These results caught the attention of the Rezidor Hotel Group, and she began her international career as a "Task Force Wellness Director," overseeing 10 Radisson Blu hotel openings in North Africa. In 2012, at the A4M Anti-Age Symposium, Tajana connected the dots, leading to the creation of her unique wellness method, "DNA Wellness." This patented and intellectually protected scientific approach to health was soon recognised by regional leaders, and she was promoted to "Sidra" Wellness Consultant, working with world-renowned experts handpicked by the chairman herself. 

By merging functional medicine tests with her back-to-nature wellness concepts, Medical Wellness became her life’s focus. Many clinics and wellness hotels worldwide (www.epiwellness.hr/projects, www.epiconsultancy.com) have since adopted the EPI Wellness protocols she developed. Tajana is determined to change the perception of the wellness industry from a focus on pampering to being at the forefront of health. Between 2021 and 2024, in the heart of futuristic Dubai, Tajana opened six wellness clinics and is now launching a new Longevity program for the well-known Dubai Premium Clinic – Al Das Medical.
