Precision medicine,
with a steady hand.

A physician-led internal medicine, menopause care, and longevity medicine clinic in Calgary — built around the kind of careful, thorough care most people remember from a different era of medicine.

Why we Exist

A clinic built for the medicine that doesn't fit a 10-minute visit.

Integria began with a clinical observation: the patients who needed careful, integrated thinking the most were often the ones the system had the least time to give it to. Complex hypertension, perimenopause symptoms that didn’t match the textbook, fatigue without a clear cause, layered cardiometabolic risk — the medicine that requires sitting with a problem rather than reaching for the next step in a protocol.

We brought together a group of fellowship-trained internal medicine specialists, certified menopause practitioners, and clinical leaders who wanted to practice that kind of medicine again. The model is private, but the philosophy is unchanged from the public system that trained us: thorough, evidence-informed, accountable. We just gave ourselves the time to do it properly.

Integria serves patients across Calgary and southern Alberta through three connected care lines — consultative Internal Medicine for referring physicians, membership-based Menopause Care, and emerging Longevity Medicine for proactive, prevention-first patients. Each line shares the same physicians, the same diagnostics, and the same standard of care.

Our goal isn't to replace the medicine that came before. It's to give complex problems the time and the team they always deserved.

Diagnostic Assessments

A single test rarely tells the full story. We combine advanced imaging, blood biomarkers, cardiometabolic and hormonal panels, and functional assessments — all interpreted together by your physician.
