Conditionally show sheets based on drop down

I'm modifying a workbook we use at our company to track disaster drills. I've attached a sample workbook to demonstrate my question. As you'll see, there are three sheets, one for each of the sample programs. The problem is that in reality, there are 50 different programs that each have a sheet and it is quite annoying to have to flip through each sheet when entering information. Putting all of the sheets on one sheet and then having to scroll down would be equally annoying. I'd like to instead create a dropdown list in cell A2 (through data validation or otherwise) where a person could select the program name that they wish to enter information for and then ONLY the corresponding grid would be displayed. I'm assuming this would need to be done using VBA but unfortunately I'm a beginner when it comes to that. Can anyone help? Thanks in advance.
