Internal Medicine

In selecting a personal doctor, have you considered a physician who specializes in ADULT healthcare?

Doctors of Internal Medicine are trained in the prevention and treatment of adult diseases.  They can serve your medical needs throughout your life, from as early as the teens (age 16) through the "senior" years.

Our doctors of Internal Medicine focus on prevention and early detection of catastrophic illnesses. They can provide screening and treatment of cholesterol disorders, heart disease, hypertension, diabetes, osteoporosis, thyroid disorders and cancer.

Annual health exams and routine sick visits can be handled by our internists, with many clinics offering same-day appointments when you are ill.

To learn more about Internal Medicine, please visit the American Board of Internal Medicine at http://www.abim.org/.
