First round logo ideas for new client

Here are some comps I worked up for my latest client who's opening a new Chiropractors office. He didn't have any specific ideas on what he would like for a logo so, I had him run through a logo reference book and show me the one's that stood out most to him. He likes a variety of styles (which makes it challenging yet fun) so, I did just that. Graphic, simple, text only. I will post the final when it's done!
