“I knew David had great experience and knowledge in business and leadership and that everything he did was backed by research and science from multiple sources.  And then, I discovered that he also had expertise in the area of health and wellness.  I asked David what his secret to losing and keeping weight off was, and he agreed to meet with me.  After asking me some questions about my health and my goals, he shared a plan on how to lose weight in a healthy manner.  I followed his guidance, and literally, the weight dropped off on a daily basis – and it came off of my most challenging area – my gut.  Within 60 days, I lost 27 pounds and went from a 42 waist to a 38 waist, and best of all, I felt great and had more energy than ever!  And then I met with my doctor, and all of my bloodwork was perfect.  And finally, this has been something that I have been able to continue to do and maintain for over a year.  I would highly recommend that you take the time to meet with David.”

“I am an allopathically trained medical doctor and neuroscientist, so I thought I knew nutrition because it was my job to restore people to health. Then, I had to reconsider. Medical education spends two weeks on nutrition; the remaining four years are spent learning how to concoct pharmaceutical cocktails. If this formula works, why are we the most mentally and physically ill and obese population of Americans to date? It is almost the norm to have multiple chronic illnesses and autoimmune issues. Dr. David Robertson understands why, and he knows how to reverse the ominous trend. He is a true expert in nutrition as he can look at a person’s medical history alone, predict what has been amiss in their diet, and advise how to rebalance their way to health. Though not always conventional, his theories are backed with infallible logic. I am wholly a scientist and a skeptic, but even I believe that a holistic approach to healthcare is far more effective at getting to the root of the issue than throwing fistfuls of pharmaceutical band-aids on the symptoms. I trust Dr. Robertson’s expertise, deep domain experience, and wisdom more than the current dietary recommendations.”

After a recent medical exam, I brought my lab results to Dr. David Robertson for a thorough review. I wanted a clear, no-nonsense analysis and actionable advice on the best path forward.

In just a few days, Dr. Robertson delivered a comprehensive Health Science Evaluation. He broke down the lab results in a way that was easy to understand and offered suggestions on how to make the information actionable. His insights covered everything from dietary changes to a prioritized list of potential supplements—what to take, when, and why. He didn’t stop there; he also offered up a practical exercise routine designed to boost both my physical and mental health.

Per his recommendation, I checked with my physician, and then implemented the information. Within just a few weeks, I’ve seen and felt noticeable improvements. My energy is up, my focus is sharper, and overall, I feel stronger.

I highly recommend Dr. David Robertson. He’s the real deal

Health and wellness have been central to my life for as long as I can remember. My journey into health science began as a student-athlete, where I experienced firsthand the profound connection between physical vitality and personal performance. Those early lessons ignited a passion that has shaped both my personal and professional pursuits, culminating in advanced education and specialization in health science as part of my doctoral studies.

What drives me is a belief in the transformative power of health science to empower people. Too many individuals face chronic health challenges that sap their energy, limit their potential, and reduce their quality of life. My mission is to provide the tools, strategies, and insights necessary to help people reclaim control of their health and unlock their full potential.

As a seasoned health science professional, my expertise is multifaceted, spanning disease prevention, cognitive enhancement, exercise science, applied nutrition, and beyond. My background as a Cognitive Behavior Scientist enriches this expertise, allowing me to integrate cognitive strategies into holistic health interventions. My focus goes beyond merely exploring symptoms—it’s about uncovering root causes and creating sustainable paths to wellness.

I am deeply committed to collaboration. Working alongside my clients, I help them make well-informed decisions tailored to their unique needs and circumstances. My approach is informed by a rich educational foundation in health science and ongoing professional development, covering topics such as epidemiology, chronic disease management, lifestyle medicine, the human microbiome, autophagy in health and disease, sports medicine, and advanced nutrition. This depth of knowledge enables me to address a wide array of health challenges with evidence-based, personalized solutions.

Whether your goals involve enhancing daily well-being, preventing disease, or optimizing fitness and performance, I am here to guide and support you. My passion for health science is not just academic—it’s personal. I am dedicated to helping you build a life defined by vitality, resilience, and lasting fulfillment.
