The Mas Clinic was born from personal frustration and refined by losses. It is the answer to a broken healthcare model. A system built to deliver the comprehensive, preventative care that every man deserves but few receive.
The Story Behind The System

Erik Bos, Director of The Mas Clinic
My journey to creating The Mas Clinic began with two distinct problems: a personal health frustration that the system dismissed, and profound family losses that revealed the devastating cost of reactive care. These weren't just personal struggles; they were evidence of a broken model. They became the mission and the mandate for what this clinic would become.
With a background spanning healthcare consulting, pharmaceuticals, and private equity, Erik understood both the potential and limitations of existing healthcare systems. At 42, he experienced firsthand the failures of reactive healthcare when he discovered testosterone levels equivalent to those of a 65-year-old man. Despite clear symptoms of hormonal imbalance, he was repeatedly told he "didn't qualify" for treatment within the conventional medical system.
This personal struggle was compounded by the devastating loss of both parents to stage 4 cancer, that could have been detected and treated earlier with proper preventative care. These experiences crystallized his understanding that the healthcare system's reactive, symptom-based approach was fundamentally flawed. (see evidence based care)
Building The Mas Clinic: A Systems-Based Solution
Drawing on his experience in healthcare consulting and private equity, Erik recognized that the solution required more than just finding better doctors, it required building better systems. Working with leading specialists in endocrinology and men's health, he continues to establish a comprehensive clinical framework that addresses the root causes of health issues rather than just treating symptoms.
Transforming Men's Healthcare
As Director of The Mas Clinic, Erik oversees the development of proprietary clinical decision support platforms that leverage machine learning to identify diagnostic patterns and continuously refine treatment protocols. Working alongside top physicians, this technology-driven approach ensures that patient care is both personalized and systematically optimized based on real-world outcomes.
After a successful pilot program in Calgary, Erik is now overseeing the clinic's expansion to Toronto, establishing partnerships within medical and wellness communities, and serving as the primary voice of The Mas Clinic brand. His vision extends beyond individual patient care to transforming how men's health is approached across the healthcare system.
The Mas Clinic represents the culmination of Erik's professional expertise to create a place where men can receive the comprehensive, preventative care that conventional medicine fails to provide. It stands as proof that with the right systems, medical expertise, and commitment to optimization over reaction, healthcare can deliver the results men deserve.
A Spotlight in the Dark
Elite outcomes are not built on expertise alone. They require a system that uncovers what others miss.
Our clinical framework moves beyond the standard, compartmentalized playbook. It synthesizes the latest in performance medicine with foundational health principles. This equips our practitioners to connect every data point, from advanced diagnostics to the subtle cues of your personal history.
The result is The Mas Protocol. This system doesn't just prevent errors. It reveals opportunities. Driving our physicians to move beyond generic protocols and design a precise, effective path to achieving your goals.
