Jimmy Diaz M.S.

IVF Research Scientist and Science Author



Hi I’m Jimmy. I was born and raised in sunny Los Angeles, California and love everything about the west coast lifestyle – the beach, the mountains, and the desert. Like many California natives, I can be a bit of a lot of things. Completed my undergraduate studies in Chemistry from University of California, San Diego and pursued a masters in Reproductive Clinical Science from Eastern Virginia Medical School. I primarily work as a clinical scientist and am also a baby maker (through IVF). I’m also a freelancer, ghostwriter, former D1 athlete, and enjoy everything I do.

Every year, I try out a new sport. But my main passions are in water sports (surfing, swimming, wake surfing, and water skiing), winter sports (skiing), and wind sports (kitesurfing). I’m an adrenaline junkie and love anything that gets my heart racing!

About us

Kartik Kumar Rathi

Second Year Medical Student 


The love for medicine runs in my family, and I love studying it not because of the privilege that this field gives but because I am highly fascinated by the anatomy of humans, the physiological mechanisms that occur 24/7 within the body, the biochemical changes, and of course, the disturbances that lead to pathology.

Anyways, I try to reflect my interest in medicine by writing research papers, various medical-related articles, and blogs to raise awareness amongst the target audience in the best possible ways and help them get the answers that they are looking for.

Besides writing, I am a founder of a social startup. I also have a strong passion for teaching and public speaking. I love sharing my insights, experiences, and knowledge with people that could help them even in the little way possible.

I aspire to be a successful cardiologist in the future because I strongly believe in connecting with people with heart 😀

Dr. Thomas O’Connor MD

Doctor and Founder of Testosteronology


  • American Board of Internal Medicine Certification – Since 2005
  • Clinical Instructor/Teaching Physician-Department of Medicine-University of Connecticut School of Medicine
  • Physician Preceptor Clinical Longitudinal Immersion in the Community (CLIC)

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.

About us

Steve Theunissen

Certified Personal Trainer and Gym Owner

Relevant Experience

  • Gym owner
  • Certified Trainer


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.
