I’m a queer trans lady, Erin Jr.’s mama, and Eryn’s girlfriend. Among other things, I’m fond of craft beer, the Defenestration of Prague, Emacs, mechanical keyboards, HTML, sapphic art and literature, various sports, Star Trek, travel, turtles (and tortoises), walking the streets and hills of San Francisco, watches, and the Web.

EJ, Eryn, and I live in San Francisco, which sits on the unceded ancestral homeland of the Ramaytush Ohlone peoples. I grew up in the Boston area, went to college in Indiana, and spent a decade in San Diego before moving up here to the Bay Area.


I manage the Web Standards & Interoperability team at Apple. Here’s my résumé.
