Vascular Surgery Associates

Vascular disease is more common with age, however people with a family history of vascular and heart disease are at higher risk, as well as women who are pregnant, or anyone who has a cardiac-related condition such as high cholesterol or hypertension. An unhealthy lifestyle can also lead to vascular problems, which is more common in people who smoke, are obese or sedentary, or those who routinely stand still or sit for long periods of time.

​Our highly qualified vascular surgeon has years of experience and is trained in treating conditions that affect the arteries, blood vessels, veins, as well as the lymphatic system.​
