Our Approach
4 Steps to Better Health

Intake Questionnaire
Comprehensive review of your lifestyle and health history. This step will screen for unhealthy lifestyle habits, sleep problems, sedentary lifestyle and social isolation.

Initial Consultation
Initial Consultation by video: We will review your health and lifestyle intake form. A comprehensive health interview will be conducted.

Diagnostic Tests
Extensive testing: comprehensive blood work, diagnostic imaging, genetic testing, and others tests as indicated.

Follow-up
At the follow-up visit (by video), we will provide an in-depth report addressing all the critical domains of health and longevity: sleep, exercise, cardiac risk, cancer risk, dementia risk, and genetic risks. We will provide recommendations on how to lower the risks and optimise health and longevity.

Diagnostic Tests
Comprehensive blood tests to assess organ functions and cardiac risk factors
Medical imaging to assess body composition. This is a much better indicator of health than BMI.
Additional imaging- including coronary calcium scan and MRI as indicated
Genetic test to screen for cancer and cardiac disease genes
Genetic Testing
We have partnered with Invitae, the most trusted name in clinical genetic testing.
"Proactive genetic testing offers healthy adults without a strong personal or family history of disease an opportunity to learn about how their genes could potentially impact their health. If so, they can be proactively monitored or offered preventive care solutions before they develop cancer, have a heart attack, or experience an adverse reaction to a medication."

MRI Scan
Timely access to CT and MRI scans are possible for those willing to travel to Quebec- there are a number of private facilities offering a full range of diagnostic imaging.

I practiced cancer medicine at the Ottawa Hospital for over two decades.After a successful career as a cancer doctor, I have decided to dedicate myself to the practice of preventative medicine.
Traditional medicine is mainly focused on the treatment of diseases- which it does admirably. However, there is an unmet need for expertise in healthy living and disease screening.
