How to keep column A from scrolling vertically

Hi,
I have data in column A, rows 1 thru 25. Then I have data in columns C thru M, all rows. I need to be able to keep the column A stationary while scrolling vertically in columns C thru M.

I included a copy of one of my sheets. I need only the green highlighted cells to always be visible when scrolling down. Any help will be much appreciated.

Thanks,
Matt
