After seeing several doctors I found Keith McCormick and yes, he knows more than all of the other doctors combined. I even went with friends when they went to their rheumatologist or endocrinologist about their osteoporosis. No one knew as much as McCormick.

No one knew as much is teeth. Thanks to him I'm not taking The drugs that everyone else insisted I needed. I took a bone QUALITY test – TBS-and it was normal. No other doctors seem to be aware of the importance or even the existence of this test.
