About
Dr. Andy Martin co-founded Modern Functional Medicine Center after more than 15 years in interventional radiology. He grew up in Texas and began his medical training at the University of Texas at Austin. He then earned his medical degree from UT Medical Branch in Galveston. His surgery internship and diagnostic radiology residency took place at Loma Linda University, where he served as Chief Resident. He completed a fellowship year at UC San Diego.
Over his radiology career, Dr. Martin performed more than 5,000 interventional procedures. He treated clogged arteries, advanced cancers, and organ failure. Those years at the bedside convinced him that medicine needed to meet patients earlier in the disease process. He brought that conviction into functional medicine, where he now uses advanced biomarker testing to uncover hidden imbalances before conditions become disabling. His clinical focus includes gut health, hormonal and metabolic dysfunction, autoimmune conditions, thyroid disorders, brain health, and mold toxicity. He holds licensure in 30-plus states and sees patients entirely via telehealth.

Frequently Asked Questions
Dr. Martin focuses on gut health, hormonal and metabolic dysfunction, autoimmune conditions, thyroid disorders, brain health, skin health, and mold toxicity. He uses advanced functional lab testing to identify root causes driving these conditions. His background in interventional radiology gives him a procedural and diagnostic depth that shapes how he evaluates complex cases.
Dr. Martin starts by asking why the body is producing a given symptom. He uses advanced biomarker testing to map underlying imbalances rather than treating symptoms in isolation. Every care plan includes personalized nutrition and supplement protocols, with check-ins every 21 days to track progress and adjust the approach.
Dr. Martin uses a range of functional diagnostics, including GI-MAP stool DNA sequencing, DUTCH Complete hormone panels, organic acid testing, SIBO breath testing, continuous glucose monitoring, NutrEval, urinary mycotoxin testing, and heavy metal screening. He selects tests based on each patient's symptom picture and health history.
Dr. Martin trained at Loma Linda University, where he completed his surgery internship and diagnostic radiology residency and served as Chief Resident. He completed a fellowship at UC San Diego. He specializes in internal medicine, functional medicine, and preventive medicine.

Dr. Martin builds personalized nutrition and meal plans into every care program. He accounts for each patient's cultural preferences, travel schedule, and family dynamics. Supplement protocols accompany the nutritional guidance and adjust over time based on follow-up testing and check-in findings.
Yes. Mold and mycotoxin toxicity treatment is a defined focus of Dr. Martin's practice. He uses urinary mycotoxin testing to identify exposure and builds targeted protocols to address the underlying burden. Patients with unexplained fatigue, cognitive symptoms, or chronic inflammation often pursue this line of investigation with him.
