Counting Time

I have a database that exports out a search but the time field is a different format, which I believe it is text format. When I do a countifs for the rep and between a time range it returns 0, which I know is obviously wrong. What formula can I do in the countifs to actually count them when the criteria is a different format? Because if I do a TIMEVALUE formula in column T and do my range as that column it works fine. But I am wanting to do this as an ongoing basis and do not want to have to worry about filling down a column, or if this ends up as a coworker using this sheet, I want to make as easy and simple as possible. I have attached my sample data as well.
