Dr Mattos is absolutely amazing. She listens, she's thorough, she's knowledgeable, and she gets results. She's the first doctor to diagnose leaky gut and IBS for me and to take my Hashimoto's seriously as an auto-immune disorder. I went from chronic joint pain, fatigue, and constipation, to regularity, no pain whatsoever, and so much energy. I also still sleep like a log. I can't recommend her enough.
