Infinite Natural Health

Infinite Natural Health is a faith-aligned functional medicine practice in Centennial, Colorado, founded and led by John Brennan, PA-C.

After years of orthopedic practice and a personal journey through injury, multiple surgeries, and incomplete conventional care, John experienced restoration through root-cause functional medicine. That transformation shaped the vision of Infinite Natural Health: to help people reclaim lasting vitality by addressing the whole person—spirit, soul, and body—rather than managing isolated symptoms.

Rooted in the conviction that God designed the body for healing and that true wellness flows from alignment with the Creator, the practice integrates advanced diagnostic testing (including comprehensive stool, blood, urine, saliva, and hair analysis), targeted nutrition, supplementation and detoxification protocols, regenerative therapies such as StemWave, personalized lifestyle guidance, and ongoing wellness coaching. Care is delivered through a program model and high-value visits designed for sustainable results.

John Brennan and the Infinite Natural Health team serve patients across the South Metro Denver area with a warm, relational approach that honors both cutting-edge science and reconnection with truth.

At Infinite Natural Health, every patient is an individual with unique purpose and God-given capacity for restoration.
