Regular MD of internal medicine. I really liked this doc because. although he is a doc of internal medicine, he will only hand out prescription meds as a last resort. He is adamant about proper diet,and emotional well being. He is big on natural healing with herbal supplemnets. The first time I saw him he spoke to me for over two hours, then he took blood, urine, saliva and stool samples. It was shocking to find a doctor who honestly cared, and the key word is honestly.
