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.
