If your site and the links pointing to it have a decent amount of trustrank then you have nothing to worry about. Others converted dozens of high ranking sites from static or other platforms to Joomla and have never had the rankings drop.
But there are things to consider, have a look at your source code and look at the code for joomla sites, see where the content is on the actual page and how its laid out, but generally speaking you can set up a joomla site to display the information as with many static pages. - and yes to be safe test it first!
