I tried to do some research on his client list, but the only lead I got is paywalled behind IMDb Pro: https://pro.imdb.com/company/co0079462/

Edit: Okay, so I found this interview with Michael Greene from 2020: https://www.backstage.com/magazine/article/la-agent-talks-negotiation-accountability-era-times-1446/

Describe your talent roster.
Great artists who want to use their talent to give back to the world and use their voices for positive change as they get more well-known.
Are industry-changing movements from #MeToo and Time’s Up to “Black Panther” and inclusion riders trickling down into your work?
I think it’s fantastic. Our client Tessa Thompson is very involved with Time’s Up and is using the inclusion rider.
Is the gender parity movement in terms of Hollywood paydays a good thing for you and your clients?
Sometimes, when negotiating, you have to say, “Are you paying her less because she’s a woman? Because the actor is African-American or Hispanic?” You make companies accountable for how they make their deals.
