Parkhill's monumental sculptures made primarily of reclaimed materials embrace the color, grain, old paint, dents, scratches, and nail holes of its previous use while transforming them into remarkably harmonious and sublime forms. With a background in carpentry, Parkhill is known for creating elegant, abstract objects, both freestanding and mounted on the wall.

"My work has always come out of whatever kind of salvaged wood comes into my studio. The work that evolves depends on the size, species, condition and so on. Oak bends readily and yellow pine barely bends at all without breaking."

Parkhill graduated from the USF in 1972. After completing a Master's degree in Fine Arts from the University of Utah, he decided to buy a house in the Seminole Heights neighborhood of Tampa and converted the detached garage into a woodworking studio. Parkhill's return to Tampa Bay has had a significant impact on the area arts community. His work is regularly featured in exhibitions and festivals, and he is the recipient of multiple Best in Show awards at St. Petersburg's prestigious Mainsail Art Festival. His art can be found in numerous public, corporate and museum collections.
