Observation over dogma

The “accidental” healthspan.

My journey into precision longevity didn’t begin in a laboratory; it began with a personal realisation. Approaching age 68, I began receiving comments from gym instructors, patients and friends who were in disbelief of my actual age, often guessing I was 15 years younger.

This led me to deeply analyse my own habits. I realised my inadvertent “Rupture and Repair” lifestyle — based on motivation, ‘hormetic’ stress and self-discipline — was the differentiating factor. I had never taken a daily medication, nor had I touched a single supplement until age 68.

This realisation sparked a deep dive into the rapidly evolving world of anti-ageing, with targeted therapies and genetic technologies. While the future holds incredible promise, my focus immediately shifted to a more pressing question: What can we do right now? And that’s what excites me.

The paradigm shift

The power of clinical reality.

In 2023, I began working extensively in a clinic offering regenerative therapies — specifically Platelet-Rich Plasma (PRP) and targeted interventions for sports injuries and degenerative musculoskeletal conditions, mainly arthritis and tendon damage in older adults.

The results of PRP therapy were undeniable. I watched hundreds of patients experience profound improvements, particularly in conditions like osteoarthritis of the knee. They returned annually for “top-ups” after going for a year mostly pain-free and functioning at a much higher level than before treatment. They returned, and in turn referred their friends and families.

Despite the successes I saw, I continually heard these same patients recount how their regular doctors would scoff at their improvements. As the medical evidence is deemed “equivocal” by some leading bodies, they withhold recommendations for PRP, so practising family doctors follow the advice, believing it is the final word. Because of this, we are currently trapped in a space where the dogma of data-driven medicine is considered the only “evidence,” while our innate human ability to analyse real-world clinical outcomes — and request regenerative treatments as a right — is actively denied, or ignored. Medical evidence is not just dry statistical data…it is the intersection of the patient’s needs and wants, the physician’s understanding and experience…and the data of studies. Data — or lack of data — is important, but only part of the whole story.

Cutting through the noise

A blueprint for “the best you”.

Today, patients are overwhelmed. The internet is flooded with influencers, celebrities, YouTube videos, TikTok trends and AI-generated health advice.

My mission is to cut through that noise. I utilise my 35 years of experience as a practising physician and researcher to do the heavy lifting for you. I do not run a traditional lifestyle clinic; I am not here to change mindsets or convince people to quit smoking and start exercising.

Hallmark Precision Health is exclusively for individuals who already possess the drive to be the best version of themselves. I work with you to develop a highly individualised, regenerative blueprint that goes far beyond the basic, standard-of-care control of weight, substance use, blood pressure, lipids and glucose.

Practising what I track

My own tracked biology.

I hold myself to the same standard of tracking and evidence I offer my patients. Here is some of my own biological data, tracked over time.

Heart rate variability

46 ms

HRV naturally declines by roughly 5–8ms per decade. By age 65+, the average baseline is well below a 20-year-old’s (who might average 60–80ms).

Heart rate range

65–172 bpm

Tracked resting-to-peak range across a recent 7-day period, including exercise sessions.

Estimated max heart rate

149 bpm

Using the standard {MHR} = 220 − Age rule of thumb at age 71 — a formula I use with patients to frame their own training zones.

MitoIQ® mitochondrial copy number

235 /cell

Buccal swab mitochondrial DNA analysis at age 69, plotted against the normal age-adjusted reference range.

Clinical focus

His current clinical practice is centred on non-surgical treatments, including the application of metabolic peptides such as GLP-1 receptor agonists and advanced musculoskeletal care.

At the clinic, Dr Rob employs Platelet Rich Plasma therapy for the non-surgical treatment of acute and chronic musculoskeletal conditions, including osteoarthritis, tendinopathies and sports injuries.

Precision health interests

Working with motivated patients has led Rob to move beyond standard care into emerging therapies, longevity education and practical health optimisation strategies.

His areas of interest include HIIT, Zone 2 training, intermittent fasting, heat and cold shock therapies, hyperbaric oxygen therapy, healthy ageing education and microbiome health.

Professional background

Patient education

Rob’s interest in research and education has led to the production of numerous educational materials for patients to access, helping doctor and patient collaborate more effectively around precision health, healthspan planning and preventive health education.
