What are Internal Medicine physicians and providers?

Internal medicine physicians and providers are “doctors for adults” who care for men and women age 18 and older. They can take care of your primary medical needs and follow you throughout your adult life. Internal medicine specialists include doctors, nurse practitioners and physician assistants — each is an important part of the health care team, serving as your main contact to help manage your long-term health and navigate the health care system.

Internal medicine specialists are trained to treat the whole person — each organ and every disease. They are skilled in diagnosing and solving health problems, managing complex medical disorders and preventing diseases – with regular health screenings, counseling and lifestyle changes - so you can continue to live well.

We have a patient-focused committee to proactively get patient feedback before implementing changes, and our nurses are available 24/7 to talk to patients and their families over the phone.

Specialized care for nursing home patients

Prevea has a team of physicians and nurse practitioners, called Skilled Nursing Facility Specialists, who focus on caring for patients in nursing homes. They are available at nursing facilities to collaborate with your primary care physician or provider and oversee your medical care from the moment you are admitted until the time you are released.
