About
Dr. Sam Madeira, NMD
Naturopathic doctor focused on environmental medicine and complex chronic illness.

Dr. Samuel Madeira is a naturopathic doctor with 14 years of clinical experience in environmental medicine, helping adults recover from complex chronic illness. That includes mold illness, sewer gas exposure, Chronic Inflammatory Response Syndrome (CIRS), Mast Cell Activation Syndrome (MCAS), thyroid disorders, hormone imbalances, autoimmune diseases and other difficult-to-diagnose conditions. His approach is evidence-informed and focused on root causes.
He is licensed as a Naturopathic Medical Doctor (NMD) in Arizona and as a Naturopathic Doctor (ND) in Montana and Washington. NMD and ND are the titles different states use for the same credential.
His clinical passion is helping patients who have often “tried everything” finally discover the underlying causes of their health challenges. He believes every patient deserves to be heard, understood and given a thoughtful, personalized plan that addresses the root causes of illness, not simply the symptoms.
He has spent the past 22 years studying herbal medicine and is passionate about combining the wisdom of traditional botanical therapies with modern integrative medicine.

Reviews
What patients and colleagues say
“Dr. Sam Madeira is one of the most intelligent, compassionate, and caring doctors I have ever met. And I’m a physician myself! He helped my partner immensely with some hormonal issues which arose after an intense period of stress. Often, doctors won’t look into people’s complaints when the basic lab numbers look “normal”. Dr. Madeira will take the time to listen to your story, order the right lab work, apply his vast wisdom and experience to create the best plan of care for you. For the best care for your best life, go to see Dr. Madeira!”
“I’ve been working with Dr. Madeira since December to resolve chronic Epstein Barr. Dr. Madeira is rigorous, tenacious, and thoroughly dedicated to helping me resolve my longstanding health issues. He uses outcome based methodology to customize my treatment plan, stays present and supportive, and non-judgemental every step of the way. At every wall I hit, he provides solutions for overcoming obstacles. … He’s unlike any provider I’ve ever worked with, and usually people like myself have seen many.”
“Dr. Madeira is compassionate and truly listens. He takes the time to look beyond band-aid solutions and digs deeper to look at the root cause. He has put a lot of time into even figuring out the most complex symptoms and provides real solutions that work. I highly recommend him as a doctor.”
