about me

My passion lies in mastering technology to bring art to life.

I can draw anything. Really, anything. If you can think it, I can create it. Even if you cannot think it, I can create it. I am a senior-level technical and scientific illustrator/animator specializing in engineering, manufacturing, patent, medical device, and biological/scientific illustration and animation. I am versed in several types of professional software creating 2D and 3D illustration, animation, and written content for web-based learning, technical manual publication, engineering R&D, product development, marketing, and litigation. My portfolio also includes portrait work, digital painting, concept art and design.
