Lifelong health doctor

Meet Dr. Kate Volmir, MD

Dr. Kate Volmir is a Board-Certified Internal Medicine physician with advanced Training in Lifestyle, Functional & Longevity Medicine.

Unlike traditional practices that rush you through 15-minute visits, Dr. Volmir provides extended visits and individualized care through an insurance-free Direct Primary Care model, allowing time for deeper clinical evaluation and long-term health planning.

A Different Model of Care

When Routine Care Feels Incomplete

Traditional primary care often operates within strict time and insurance limitations. This can leave little room for comprehensive metabolic and endocrine evaluation.

Life Long Health focuses on thorough clinical assessment and physician-directed care plans designed around your individual biology.
