Your Blood Work Is Talking. Your Doctor Isn’t Listening. I Am.

For executives and high performers who’ve been told they’re “fine” — read against optimal ranges, not population averages, then turned into your protocol.

“Normal” Isn’t the Same as Optimal. Your Labs Prove It.

Standard bloodwork reviews check whether your numbers fall inside a lab reference range built from a population that includes the chronically ill, the sedentary, and the untreated. That’s the bar being used to tell high performers they’re “healthy.”

It’s not good enough, not for someone running a company, closing eight-figure deals, or making decisions that affect hundreds of employees while running on five hours of sleep and adrenaline.

THE PARTNERSHIP

Tom’s approach. Revi’s measurement.

Tom is a Certified Functional Bloodwork Practitioner and Advanced Functional Health Practitioner. He reads what your labs are actually telling you, then builds the protocol to fix it.

About Tom

Tom is a health and wellness professional with 10+ years of experience delivering personalized coaching programs built on one non-negotiable principle: decisions get made from data, not assumptions.

His clients are career-driven professionals, executives, founders, and high performers, who have spent a decade optimizing everything except the one system that determines whether any of it is sustainable: their own physiology. They’ve been told they’re “fine” by a GP running a 10-minute checkup. Their labs say otherwise.

His approach integrates functional medicine, performance coaching, and behavioural change science because chronic conditions and stalled performance are rarely solved by a single lever. They require an assessment of the whole system.

ZENITH’S COMMENTS: TESTOSTERONE

Zenith

17 nmol/L is within the laboratory range but below Optimal for most men over 40. Testosterone however should never be viewed in isolation. My assessment considers this alongside your free testosterone, SHBG, LH, FSH, prolactin, oestradiol & glucose levels before providing the recommendations.

WHAT WE TEST
