Personalized, comprehensive family medicine for a lifetime

When you choose a Star Valley Medical Center family doctor, you’re not only getting a board-certified physician, you’re getting a life-long, trusted friend. Our family medicine physicians are dedicated to improving your quality of life, from birth to each stage of life that follows.

Providing high-quality, patient-responsive medical care for a lifetime

People who have an ongoing relationship with their family healthcare provider often experience better continuity of care, higher quality of life, and lower health care costs.

Here’s why:

Family doctors follow your health and well being throughout your life cycle.
They are familiar with your ongoing medical and family history.
They help manage chronic conditions (e.g., heart disease, diabetes and arthritis).
If needed, they refer you to specialists who fit your specific needs and personality.
- From there, they act as your guardian to ensure medications and treatments (ordered by specialists) do not result in dangerous drug interactions, and contraindications are respected.

Simply put, if your doctor knows what’s normal for you, they’re better equipped to determine what’s not normal. Physicians with intimate knowledge of your medical history can often make an earlier diagnosis than a doctor who does not have prior knowledge of your health.
