Hi Errick
You have some pretty heavy exact match anchor text in your backlink profile for "houston business lawyer". Beyond that - the entire site is built around that phrase - "Houston Business ______" - either lawyer or law service. My opinion - crawlers have caught on to your heavy optimization of this on your site, even your domain name, and it probably tripped spam filters.
I would consider going through your site and easing up on such heavy utilization of "(local) Business (lawyer/service)". The site does have quite a bit of a "spammy" feel. There's no real association on the site to Mastriani Law Firm beside the logo. This is a HUGE opportunity you are missing, as people could be searching for the attorney by name.
I also found http://www.texasdebtdefense.com/ which seems to be the same attorney. The site has the same issues - just to let you know. This particular site also has a pretty bad backlink profile - lots of directories and pretty obvious old-school-SEO link building tactics being utilized. Be careful here too, because both these sites, if they are on the same IP address and have the same WhoIs data, could also trip more spam signals.
Please look at the links I posted above, take an honest assessment of the website as it is, and start optimizing your site in a more natural fashion with branding for the law firm; not just exact match keywords repeatedly. Hope this helps! Good luck!
