OK...so we are looking for some sort of icon, or visual symbol--probably incorporating the text "Affiliated Dermatologists" somehow--but not necessarily in the symbol itself. That is, if the visual is engaging but doesn't really "mesh" with the text, the words could be physically separated from the icon/picture (like under it, for example).
Word associations/ideas: elegant, flowing, fluid, contemporary, cutting edge, fresh, energetic, robust, renewal, pretty but not fussy. We're relatively near the ocean, and I like the feel of "ocean", but one of our colleagues is "Coastal Dermatology", so it can't be too close to his look (http://www.coastalskincare.com/dr_kaplan.html). Many colleagues incorporate some semblance of a female image (http://www.venturaplasticsurgery.com/), but this is just one possibility.
Orange is probably not a good color--either for your skin or our logo!
Yellow might not copy well.
Don't be afraid to push the envelope! We want to attract attention, but not be so fringe as to scare away the seniors.
