I contributed to Spark, a Drupal distribution for an improved authoring experience, including in-place editing, responsive previewing, and advancements in accessibility and usability. Much of this work is now part of core. I assist with theme development and CSS-related issues in the forums and whenever I can on IRC as prestonso.
My freelance studio (est. 2004) provides Drupal-specialized services.
I co-founded the Southern Colorado User Group (SCUG) and helped manage it until 2009. I am also part of the Denver/Boulder and Boston user groups.
