So looking at this page we can see that you have chosen to include lots of additional scripts that are adding significant weight to the page and load time. Every time you add widgets, or custom code you can impact page load. When looking for performance gains you need to weigh the impact to the users experience. If I was consulting with you we would review these feature by feature and then make decisions to remove some and mitigate others. You have to understand code and web performance fundamentals to make decisions. Google is penalizing sites for bad ones now.
Example; Google maps are cool but are a huge impact on performance and are not frequently used by visitors. Alternately one could use a static image of a map (open source) that links to a page that has a dynamic map for those that need it.
You should either research this for DIY or hire a professional.
