Choosing a healthcare provider to partner with you on your path to good health is so important. Our experienced primary care physicians and mid-level providers offer preventive care as well as diagnosis and treatment of acute or chronic conditions.

What is Primary Care?

Primary care is a specialty area that includes family medicine, general practice, internal medicine, obstetrics/gynecology and pediatrics. The field is designed to offer you a physician who is your medical home – a provider who is your primary health contact, knows all aspects of your health and strives to help you improve it.

  • Family medicine – Cares for the entire family, including adults, children and seniors. They provide complete care, including wellness and disease prevention, diagnosis, and treatment of a wide range of health conditions, including chronic disease.
  • General practitioners – Treats acute and chronic illnesses and provides preventive care and health education to patients.
  • Internal medicine – Provides comprehensive, lifelong care to adults of all ages; focuses on prevention, detection, management and treatment of long-term or complex health conditions.
  • OB/GYN care – Provides care of women during pregnancy and childbirth and in the diagnosis and treatment of diseases of the female reproductive organs. It also specializes in other women’s health issues, such as menopause, hormone problems and infertility.
  • Pediatric care – Care for children ranging from newborn through age 21.
