Welcome to the Q&A Forum

For starters, I'd add the NOODP NOYDIR meta robots tags to your pages.  That tends to do a pretty good job of keeping Google in line (i.e. using your meta descriptions and page titles in the SERPs). Recently I've noticed that Google will often attempt to extract your company name and prepend your page title with it. e.g. if your page title is "Purple Widgets - ACME Inc." and your URL is www.acmeinc.com, Google will show "Acmeinc: Purple Widgets" in the SERPs for your headline.  This seems to be new as of a few months ago, and NOODP NOYDIR doesn't seem to stop it like it used to.  But I'd try NOODP NOYDIR because it does USUALLY still seem to have the effect you're looking for.
