Nice professional site. I like it. Just a couple quick thoughts:
1- Your name, address, and phone number should be in the footer. The phone number can be other places too. Having all this info together, on each page, helps your local SEO.
2- "About Us" should be it's own page. Put as much personal information on the page as you can, including a headshot of any owners or managers clients will be most likely to deal with.
