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.”
