The first text element in the site is the alt tag of an image of "logo".
This explains where it is coming from, as to why slightly stranger.
Look through your source I see no real paragraphed block of text. All of the text seems to be quite short, fragmented sentences.
When google has to create a description by itself it normally tries to find a suitable paragraph containing the keyword. Since I can't even see your keyword within the page, this may explain why google fails on making a relevant description and simply uses the first sentence (single word) it finds.
Solution 1) Add some well written text containing your keyword.
Solution 2) Add a description meta tag.
