I've designed and built user interfaces for websites and apps (web/mobile) for a lot of different industries... most notably: K-12 education (all subjects for students and teachers), high education (university programs & conferences), technology, health & well-being, doctors, vacation rentals, athletics, resorts, ecommerce (products & services), clothing, pet stores, automotive (selling & racing), travel, and much more! Here are a few samples.

I've created hundreds of wireframes, whiteboard drawings & workflows, etc. The following are a select few that I've done. Wireframes are an essential part of building anything interactive (no matter what it is). Typically I would start with sketches (yes, pencil and paper!) or outline layouts on a whiteboard. If the wireframes needed to be tighter (say, if the interface was fairly complex) I'd create them in a wireframing program.

Drawing and creating illustrations is a second passion of mine. I've been drawing since I could pick up a crayon and haven't really stopped. The following is a collection of pieces that were done with a variety of media and purpose.
