how to find a highest grossing agent in an area?

[Dennis Nikolaev]

I am trying to find the 3 highest-grossing agent teams in San Diego (mission valley, el Cajon, Santee).

What is a reliable way to go about it? (I am not looking for recommendations/self-introductions, I m looking for a source of statistical info).

I went to Zillow but it gave me 25 pages of agents without letting me sort it. Any other ways to see the number of recent sales by an agent?
