Family Practice

Family practice is a specialty of comprehensive health care for people of all ages. Family physicians diagnose and treat illness, provide preventive care, including routine checkups, health-risk assessments, immunizations and screening tests, and offer personalized counseling on maintaining a healthy lifestyle. Family physicians also manage chronic illness, often coordinating care provided by other subspecialists.

Geriatric Medicine

Geriatric Medicine is a specialty that focuses on medical issues and diseases of aging. A Geriatrician most often treats people over the age of 60 who are either healthy or have multiple medical issues. Medical care becomes more complex as you age and develop more conditions. A Geriatrician is an expert in how medical conditions impact one another, in how medicines interacts, and how medical conditions and medications uniquely affect you as you age.

These physicians provide primary healthcare and manage most chronic illnesses, such as high blood pressure, high cholesterol, and diabetes. They apply scientific knowledge and clinical experience to determine the appropriate diagnosis and treatment for their patients.
