This concept was inspired by Tacoma, the city of destiny, and your slogan. The bridge is a representation of the Tacoma Narrows Bridge. More importantly, though, it symbolizes "...The Gateway to a Healthy Body". The single curve that lies outside the dome, is a smile. The dome shape is inspired by the Tacoma Dome. The star represents the destiny: a perfect smile, great health. I think this logo is flexible, so that if you do partner up, it can adapt. ...As long as you don't move out of Tacoma, or change your awesome slogan :) I used purple/blue and gold because they are also colors of Washington Huskies, but I picked shades that are also symbolic in Dental/Medical industry. Gold represents destiny, glory, richness, ultimate achievement. Purple represents majesty, wisdom. Blue represents harmony, tranquility, confidence, trust.
Thanks for the feedback. This is a variation based on your feedback. Note: Having your slogan below your name is totally your option when the time comes to designing stationary, marketing and/or collateral materials. The final logo files that you receive from the winner will be vector and are completely editable. So you can tell the designer that will be doing your business cards for example, to not use the slogan.
