I'm not at all familiar with his work, as it's mostly for Archie Comics, and I haven't bought an Archie book for 40 years!
But I do hope that perhaps his association with Archie might mean that the term "Archie Legion" will finally change from an insult to a compliment. The early PZH Legion holds up pretty darn well.
Also, he created the Archie Universe's first openly LGBTQ+ character, Kevin Keller. That's certainly a good sign.
Sorry there's no links to relevant articles, I'm paranoid about keeping my phone virus-free. But here's his Wikipedia entry.
