About Our Practice
Personalized medicine, grounded in science.
Integria Precision Medicine is a physician-led internal medicine clinic providing referral-based consultative care grounded in thorough diagnostic evaluation, detailed clinical assessments, and evidence-informed management and risk reduction plans. Our services are covered under the Alberta Health Care Insurance Plan (AHCIP), with no out-of-pocket cost to referred patients.
We specialize in the comprehensive assessment and management of complex medical conditions, with focused expertise in resistant and secondary hypertension, cardiovascular risk reduction, metabolic health, and complex menopause care.
Our approach integrates detailed evaluation, advanced diagnostics — including in-house ambulatory blood pressure monitoring, 24- and 48-hour holter monitoring and 14-day event monitoring — and individualized management strategies tailored to each patient’s unique physiology and clinical presentation.
We work collaboratively with family physicians and specialist colleagues, providing clear diagnostic reasoning, comprehensive consult reports, and actionable management recommendations that support high-quality longitudinal care and preventative health strategies.
