can't pull greatest date using criteria

working in a workbook and need to summarize on the first page. Each workbook page has the same format, Colume A is the team name, B-J are columes of data and colume K is the completion date. The teams are listed more then 1x each, and I need to pull the greatest date in colume K associated with each team, but only need the team name listed and the greatest date showing in the summary page. I thought I had it with this formula, only to see that it's pulling the greatest date in the range, not the greatest date associated with the team.
=MAX(IF(Queries!A18:A153,"Financial Services",Queries!K18:K153))
