Tona Law was an absolute pleasure to work with. As a local ART and Custom Framing resource, we helped to enhance their new offices, with beautiful and sophisticated, well curated artwork. Tom and his team were closely involved in all of the selections, and the environment is warm and friendly, as a result. Everyone at Tona Law, is considerate and professional.
