The Longevity Functional Medicine Difference

Our Founders, Dr. Pavlovic and Shawnee Starr are deeply invested in the concept of helping individuals improve their health in a sustainable way that addresses the root cause of disease and helps them heal and recover so that they can live a life of optimal health and wellness.

Dr. Pavlovic D.O. has years of experience in functional medicine and chiropractic care. He spent many years as a Director of Hospice, where he refined his bedside manner and gained compassion for those in pain. Dr. Pavlovic witnessed firsthand how traditional medicine failed patients and recognized the missed opportunities to turn their health around using alternative medicine. Today, Dr. Pavlovic is on a mission, fueled by his experiences, compassion, and understanding to combine cutting-edge technology and holistic medicine so his patients can enjoy life to the fullest in optimal health.

Shawnee Starr is a Motivational Educator and Lifestyle Coach. Her most motivating role is as a breast cancer survivor who healed herself through unconventional means. Shawnee centered her healing around lifestyle change, reducing her intake of toxins, ensuring her hormones were balanced, improving her nutritional absorption, and reducing her stress levels. These methods allowed her to heal, regenerate, and thrive. Today she wears the crown of a breast cancer survivor with pride.

These two individuals come together as a powerhouse duo, looking to help others who are ready to take the next step and commit to a healthier lifestyle and wellness plan, with the outcome being optimal health and longevity. Working alongside a team of nutritionists, therapists, and doctors, they treat various health concerns and chronic diseases by combining functional & holistic medicine.
