During his Internal Medicine residency in Denver, Dr. Craig served on the frontlines of the COVID-19 pandemic, navigating the ICU in one of the most demanding periods in modern medicine. That experience sharpened his clinical instincts and revealed the limitations of reactive care — and drove him toward a different approach. He immersed himself in regenerative medicine, longevity science, and aesthetic therapies, pursuing advanced training in ozone therapy, IV therapy, peptide protocols, HBOT, GLP-1 weight management, and medical aesthetics. In 2024, he founded RAVE: Regenerative Aesthetics & Vitality Experts — a clinic built to fuse internal wellness with aesthetic medicine under one integrated roof.
