"Bill's design brought an unprecedented level of peace and order to our backyard. His openness to collaboration and willingness to let us be involved as much as practical was really appreciated."
"Bill understands our long term values for our property and has addded to our lifestyle in ways we are still discovering. Working with Bill was a totally fun experience."
"Every now and then I think I see a cloud in the sky that resembles Bill Tonnesen’s face. Then I realize it is Bill Tonnesen wearing a white shirt. I once saw Bill at an art museum. As soon as he walked through the door everyone wept, even the men. After that he made them all mop the floor so no one would slip on their tears and ruin the art even though none if it was as good as his."
FOUNDER, WORKSITE INCORPORATED
"I can always count on Bill Tonnesen and his crew to perform above and beyond my expectations.
Frequently the design process doesn't end with the finished plans, much of the resolution and refinement of the design occurs in the field during construction, Bill's crew understands this critical concept and always makes my projects better with their involvement."
RICHARD DORIA, RA
PRINCIPAL, DORIA ARCHITECTURE
"Regardless of the budget or scope of the project, Bill will transform the most mundane space into art. His work is commanding, subtle, and beautiful, and I couldn’t be happier with what he has done with our home. Every time I step out in the morning or pull in after a long day, I’m rejuvenated by his vision and craftsmanship.”
JEFFREY T. ANDELORA, PHD
