Arielle Unger, certified Epigenetic Coach

Arielle Unger is a certified Epigenetic Coach who has been working to optimize health through a genetic lens for several years. She graduated in 2007 from Arizona State University summa cum laude with a BA in psychology. After her husband got diagnosed with stage IV cancer at the age of 25 she took a deep dive into researching health and wellness, which eventually led her down the road to individualized health and epigenetics. Knowing her bent for health research, friends and family would come to her for advice and although growing up she always loved nutrition, she knew she did not agree with the conventional methods and direction of the “one-size fits all” model. This indirect journey eventually led her to find the functional approach to overall health. Now she guides men to optimal health through epigenetic and functional nutrition tools!

Desiree Champagne

There is an overwhelming amount of information on diet and supplementation in our world today. I can use knowledge of your genes, environment, and goals to guide you to the specific nutrients, supplements, and lifestyle habits that provide support specifically for you.  The results are not only life-changing but will save you time and money and frustration. I also specialize in supplemental therapies, mind-body connection, and interpersonal relationships. I believe that you are so much more than the sum of your genes. I will help you express your full potential.

Why Preventative Medicine?

You know, the current healthcare model is broken. It doesn’t work. It focuses on treating disease. It’s reactive, it’s passive, it’s one size fits all.

We need to change the paradigm. We need to take responsibility for our health. We need to be proactive, address the underlying cause of disease before it starts and emphasize prevention. It’s a whole body approach to optimizing your health and performance. And it’s individualized.

And that’s why I’ve committed to empowering men like you to take control of your health to achieve high performance.

Because men who are functioning at optimal levels and being smart about their health are more powerful and present husbands and fathers. And that’s my true mission.


Dr. Gapin is board certified by the American Board of Urology and is a Fellow of the American College of Surgeons.

After his undergraduate education at Texas A&M University (Gig ‘Em!) and medical school training at the University of Texas Southwestern Medical School, he completed a general surgery internship and urology residency at the University of Florida.

Dr. Gapin combines his compassion and extensive experience with men’s health care and cutting-edge technology to offer patients individualized, state-of-the-art care. He has been a true pioneer for innovation throughout his medical career.

In 2006, Dr. Gapin was the first urologist in Sarasota, FL to perform robotic surgery.

In 2013, Dr. Gapin was the first urologist in Sarasota to perform MRI-guided targeted fusion biopsy for prostate cancer detection, which has since become the standard of care.

In 2013, he was the first board-certified urologist in Sarasota to perform High-Intensity Focused Ultrasound (HIFU) for minimally invasive treatment of men with prostate cancer. HIFU has since been FDA-approved for use in the US and has become widely recognized and utilized as a safe, effective treatment option for prostate cancer with minimal treatment-related side effects compared to traditional options.

Dr. Gapin founded Sarasota Prostate Care in 2014 to provide MRI-guided targeted fusion biopsy and HIFU for prostate cancer patients.

In 2017, Dr. Gapin founded Smart Men’s Health, focused on optimizing male performance. He offers a personalized path to helping men maximize sexual health, testosterone levels, and prostate health.

As Featured In


We have combined cutting edge genetic & epigenetic science with physiology, biochemistry, brain/peak performance, hormones, lifestyle, and positive psychology for personalized solutions so you can access your limitless potential to thrive.

Executive Men's Telehealth

We provide concierge-level executive health and wellness expertise utilizing leading video-based telemedicine technology.

The rise of telehealth offers patients instant and convenient medical care from the comfort and safety of their own home. Virtual consults also empower men to seek treatment for issues they might not otherwise address because of time, convenience or embarrassment.

Individualized Medicine

We emphasize science-based precision medicine, personalizing every health decision based on your unique genetic blueprint.

Your genetic code determines how YOUR body best responds to health interventions. No more guessing! Every man is different, and thus needs to be treated differently. The one-size-fits-all approach to health and wellness doesn’t work!

Personalized Performance Blueprint

We take a whole-body approach to health. This means that we focus on how all inputs affect the human system – not just testosterone!

In fact, did you know that testosterone is only responsible for maybe 10-20% of your health and overall performance? For you to lose weight and regain your energy and focus and confidence, and feel like a man again, you need a lot more than just testosterone.

We emphasize a proactive approach to optimizing your health, focusing on 6 key areas – nutrition, sleep, detox, fitness, hormones, and mindset.

Anti-Aging & Longevity

We utilize cutting-edge age management protocols to reverse the aging process and expand longevity.

Through incredible research, we now understand that aging is an actual disease that develops from issues with cellular efficiency, cellular damage, and hormone deficiency. We have also learned that aging can be not only delayed, but actually reversed.

And we now have sophisticated tools to measure our physiologic age so we can objectively track the aging process.

Data-Driven Performance

Track and leverage your biometric data using state-of-the-art wearable technology to truly optimize your health. If you can measure it, you can manage it!

Wearable devices allow us to continually monitor various aspects of your health, such as sleep (quantity and quality), physiologic stress, fitness level, recovery status, and blood glucose levels.

This data provides real-time precision insight into your physiologic state that we can analyze to determine what works best for your body. We leverage that information to optimize every aspect of your health.
