Dr. Justin Marchegiani, D.C.
Transforming Lives Through Functional Medicine and Holistic Wellness
Dr. Justin Marchegiani's journey into functional medicine began with a pivotal realization during his early medical training at the University of Massachusetts. Initially drawn to the precision and immediacy of surgical medicine, he spent countless hours in operating rooms, witnessing the remarkable ability of conventional medicine to address acute trauma and emergency situations. Yet, as he observed patients returning repeatedly with chronic conditions—diabetes that wouldn't stabilize, heart disease that progressed despite medications, and obesity that resisted traditional treatments—he began questioning whether there was a deeper story to tell.
This curiosity sparked what would become a lifelong mission: understanding not just what was happening in the body, but why it was happening in the first place.
A Different Path Forward
After completing his degree in Kinesiology and Pre-medical studies at the University of Massachusetts, Amherst, Dr. Justin found himself at a crossroads. Rather than following the conventional medical path, he was drawn to a more comprehensive approach to healing—one that viewed the body as an interconnected system rather than a collection of separate parts.
This perspective led him to Life West University, where he earned his Doctorate in Chiropractic. But for Dr. Justin, graduation was just the beginning. He recognized that truly helping people meant understanding the intricate relationships between nutrition, hormones, digestion, detoxification, and neurological function. This realization launched him into an intensive period of specialized training that would span over a decade.
The Art and Science of Root Cause Medicine
What sets Dr. Justin apart is his unique ability to bridge the gap between cutting-edge functional medicine testing and practical, sustainable treatment protocols. As a licensed chiropractor in both Texas and Kansas, he's developed an approach that doesn't just manage symptoms—it investigates and addresses the underlying imbalances that create them.
His practice philosophy centers on truly understanding each patient's story: how did they come to be in their current health situation? What life events, stressors, environmental factors, or gradual changes led them here? While simultaneously examining these personal circumstances, Dr. Justin meticulously investigates the underlying root causes—whether hormonal, nutritional, infectious, or toxic—that may have contributed to their condition. This dual perspective allows him to create comprehensive healing plans that address not only what's happening in the body, but why it happened and how to prevent it from recurring.
One of the most challenging aspects for patients to grasp is that there are often multiple root causes operating simultaneously. A person's fatigue might stem from thyroid dysfunction, chronic infections, nutrient deficiencies, and adrenal stress all at once. Dr. Justin's expertise lies in his systematic approach to evaluating all body systems—digestive, hormonal, detoxification, immune, and neurological—then prioritizing which root cause stressors to address first. His years of clinical experience have taught him that the order of operations matters tremendously; addressing issues in the wrong sequence can slow progress or even create setbacks. By carefully orchestrating the healing process, he ensures that each intervention builds upon the last, creating momentum toward optimal health.
The approach is refreshingly thorough: the body has an incredible capacity to heal itself when given the right tools, environment, and understanding of what disrupted its balance in the first place. Whether working with elite athletes seeking peak performance or individuals struggling with complex chronic conditions, Dr. Justin approaches each case like a detective, carefully piecing together both the life story and the biological puzzle of each person's unique health journey.
Beyond Traditional Healthcare
Dr. Justin's expertise extends far beyond the typical scope of chiropractic care. His deep understanding of clinical nutrition allows him to identify how dietary choices and nutrient deficiencies impact everything from energy levels to immune function. His training in rehabilitative exercise means he can help patients not only recover from injury but build resilience against future problems.
Perhaps most importantly, his extensive background in functional medicine enables him to interpret laboratory tests in ways that reveal hidden patterns—patterns that might explain why someone feels exhausted despite “normal” blood work, or why their digestive issues persist despite trying countless remedies.
