Dr. Hansen does seem to know his stuff, but I wouldn't say that he's very professional. When I see him, he talks my ear off and cuts me off when I try to get a word in edgewise. His office smells strange and he speaks very loud too. He diagnosed my problem right away as well so I would suggest going to him if you are or were pregnant. My initial opinion of him is that he's rather arrogant and thinks quite highly of himself.
