Your font comment, just because I capitalized both words, perhaps better not to in the logo?
Also, can you make 'prescribe' all one color, rather than separate - for 51, 52, 53 for example.
Also, assuming the people represent - business person, surgeon, nurse, or asst with mask, and dr/dentist for front. I like the use of the colors being in same order of people images.
Is the circle meant to be like a looking glass or magnifying glass for "searching?" Maybe one that makes that more an option?
Anyway for the people to be more of similar sizes? possibly incorporate a fourth in yellow to represent entry level ee's too?
