As you can see from the Pingdom test result provided by @fdsa and also from here, your site seems to be loading fine. There are a few suggestions, though.
- Setup a caching layer (using WP Super Cache, W3 Total Cache, Batcache, Varnish, or anything that fits your server)
- Remove outdated and/or unsupported plugins. For example, your site seems to be using Reed Write plugin, that is compatible only up to 3.2.1 (as of today's statistics).
- Load Contact Form 7 plugin's CSS and JS files only when needed. They are unnecessarily loaded on the front page.
