Areas of focus
Care for complex, chronic conditions

Mold illness & mycotoxins
Mold toxicity from water-damaged buildings, plus heavy metals, sewer gas and other exposures that quietly drive chronic illness.
Learn more →CIRS
Chronic Inflammatory Response Syndrome (biotoxin illness), often linked to water-damaged buildings.
Learn more →MCAS
Mast Cell Activation Syndrome: reactions to foods, smells, heat and stress across many body systems.
Learn more →Thyroid & autoimmunity
Hashimoto’s thyroiditis and other autoimmune conditions, approached by looking for what is driving them.
Learn more →Chronic fatigue & Long COVID
ME/CFS, Long COVID and hard-to-diagnose conditions, especially when labs come back “normal.”
Learn more →Hormones & longevity
Low testosterone and hormone balance, plus metabolic health, performance and healthy aging for busy professionals.

Tired of managing symptoms without answers?
Maybe you’re tired of managing symptoms and want to understand what’s actually driving them. Maybe you suspect your home, your workplace or a past exposure is part of the picture. If so, you’re in the right place.
Healing from complex chronic illness isn’t a quick fix. It takes commitment, and it’s a partnership. Dr. Madeira works with adults who are ready to do the work.

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.”
