to get an idea of current logo
Use existing logo font for TRG and remove "- Truett Realty Group -"
We like the black on white and white on black. Perhaps incorporate a slight touch of red somewhere to demonstrate that we're passionate.
We'd like to box in the TRG and add the slogan "Building Outside The Box" likely outside the box or we can have a partial box that isn't complete and have the slogan start inside the box and end outside the box.
Please use your creativity.
