Professor, Doctor, and Researcher.

Dimitar graduated from the Medical University of Varna, Bulgaria with flying colors and jumped towards pursuing his PhD right away. One of the lessons he learned in med school was that “prevention is better than cure”. This is why he turned his focus on work and research in the field of nutrition. He’s also a specialist in Nutrition and Dietetics, which in Bulgaria is a medical speciality.

As a dietitian, he helps people make the proper lifestyle changes and successfully manage or even avoid some of the most common and deadly chronic diseases.

About us

Steven Theunissen

Certified Personal Trainer and Gym Owner

I’ve had a passion for health and fitness ever since I was a kid. When I was ten, I was stricken with a bad case of glandular fever. I was stuck in bed for months. My house was right next to my school and every morning I’d see, my schoolmates go running past during their physical education sessions. On one occasion, my doctor was visiting to give me a check-up when the kids ran past. He commented, “If you tried to run like them, you’d probably die!”

That comment fueled me to build up my strength, fitness – and confidence. I started working out in my bedroom then, at 15, joined the first gym in my hometown of Rotorua, New Zealand. I came to love fitness and soon managed to combine it with my other great love, writing, to produce a series of audio fitness courses that I sold through the local TV Guide. Within three years, I was managing my own gym. In 1987, I became the first personal fitness trainer in New Zealand, with the opening of Ultimate Bodies One-on-One fitness studio.

Dr. Thomas Oconnor (1)

Dr. Thomas O’Connor MD

Doctor and Founder of Testosteronology

After many years of caring for thousands of men on testosterone and anabolic steroids Dr. Thomas O’Connor created Testosteronology, a sub-specialty of Internal Medicine. No other medical specialty offers comprehensive and personalized medical services for men on androgens; Testosteronology is distinct from Endocrinology and Urology. Testosteronology is more specific than Endocrinology, which deals with all hormones in men and women. And it is different from Urology, a surgical specialty that does not focus on the common medical aspects of how androgens effect men. These aspects include cardiovascular complications, adverse effects on red blood cell production (polycythemia), psychological side affects of androgens, and other internal medicine related conditions. Testosteronology offers men from all over the world a safe place where they are respected, listened to, and protected by the most cutting edge, progressive men’s heath physicians on earth.
