Need to fix Website Loading Speeds

website: https://www.balancestudio.com

my webpage is having a hard time loading, it takes forever. ran a online speed test using Pingdom and received the following suggestions:

1. Minimize redirects:

Remove the following redirect chain if possible:

https://www.balancestudio.com/
https://www.balancestudio.com/page/
https://balancestudio.com/page/

2. Specify a Vary: Accept-Encoding header:

The following publicly cacheable, compressible resources should have a “Vary: Accept-Encoding” header:

https://balancestudio.com/page/
https://balancestudio.com/page/?custom-css=1&csblog=1&cscache=6&csrev=0
https://balancestudio.com/page/wp-content/themes/balance-1.0.1.2/css/style.css
https://balancestudio.com/page/wp-content/themes/balance-1.0.1.2/js/balance.min.js
https://balancestudio.com/page/wp-content/themes/balance-1.0.1.2/js/vendor/modernizr.js

3. Leverage browser caching:
The following cacheable resources have a short freshness lifetime. Specify an expiration at least one week in the future for the following resources:

https://balancestudio.com/page/wp-content/themes/balance-1.0.1.2/css/style.css
https://balancestudio.com/page/wp-content/themes/balance-1.0.1.2/js/balance.min.js
https://balancestudio.com/page/wp-content/themes/balance-1.0.1.2/js/vendor/modernizr.js

any help with this is appreciated! thank you!
