Hi there, thanks for the opportunity to weigh in.

I like the colors - the slate grey and blue is nice... but on your home page, I'm expecting those boxes to be clickable. Otherwise, I think it's the wrong presentation for what is otherwise a good message.
Considering that you have ten seconds to give your visitors a reason to click deeper into your site I'd say you're wasting a lot of that precious above-the-fold space with the long blue bar and three boxes. If they went somewhere [like the blue bar, is essentially a call to action, and should be linked to your services page, perhaps] then it would make more sense to me.
But I notice you don't have a services page - would make a good addition as people don't usually go to the About page to look for the list of services.
Also, Google ads do not belong on a business website - ever.
I'd love to see some images, even just a single pic of you, the service provider, on the About Us page... it's a stark set of pages without a single graphic - something to think about.
It would be wise to scan the site for spelling and grammar quickly as well. I noticed a very few minor mistakes as I scanned through the site.
Hope that helps!
