Happy Clients
  • BX Worldwide
    “Thank you so much for your hard work and lightning fast turnaround.  We got what we asked for and then some.  You have a great eye for design and did I mention you are fast!  I’m so happy I’d wear a sandwich sign with your business name on it and stand on the street corners for a week.  Is that weird?”

    Kris Young, Vice President
    BX Worldwide

Big scary leaps & other unmentionables

Nearly a year ago I started a big creative project that I had no business starting. Today, I’m reporting in from my free fall.

A Web Developer’s Rucksack

This is my coding cave. It may look like my office with the blinds drawn, but don’t let that fool you.

Portraits + Landscapes

I haven’t scribbled out all that many portraits in my life, but every time I do, I feel a strange sense of connection with what I’m seeing.

Share & Show

A behind-the-scenes tour of the projects that are in progress over here. More “show” than “tell” in honor of the current end-of-year busy season.
