I think this looks right in terms of textual offering and visuals, so I would not necessarily agree with downsizing what you have written because you are in a large marketplace for arborists, you are educating your potential and existing clients, and giving Google a lot to index plus links to other sites for reviews, etc.
I do wonder why you have not incorporated the logo you have on your avatar at the top of the header block rather than at the footer, because that should be an immediately recognizable device to tell people they reached YOUR website. I would consider altering that.
I also think it would be good if you could give a pop of color to the home page with the social media links, and making them stand out by using their native color scheme (blue for Facebook, red for Yelp! etc...)
Nice you've linked the testimonials tab to outside review sources and I hope you will solicit reviews on those platforms as fast as possible. One nice trick is to give happy clients a little card that has a QRC code to go straight to those reviewing sources by scanning with their mobile phones and giving you a rating at least.
Hope this is helpful.
