Sharp and progressive logo, healthcare tech company

Allied Healthcare Solutions

I am a recent college grad and an aspiring entrepeneur. I am very friendly, very outgoing, love technology, and I have a keen business sense. I use technology (specifically Apple products) wherever possible to make my life easier. I'd like my logo to embody my youth, bold personality, and love of technology. Although I want to showcase these attributes I still want my logo to appear professional and serious regarding my services.

My target audience is physicians (both established and upstarts) and healthcare businesses (home health, nursing, etc.). This target audience will range from well tenured doctors (60+ years old) to emerging healthcare professionals (24+ years old).

Because I am not targeting any specific socioeconomic group, I would like my logo to appeal to clients of all ages, backgrounds, & origins.

I would like particular focus to be placed on the "A" in "Allied Healthcare Solutions". I would like to use this "A" by itself as a logo when space does not permit the use of the full company name. Clients should be able to recognize my company by this "A" itself, as well as by the company name in its entirety.

I'd just like to stress the importance of creating a "progressive yet professional" look. That being said colors chosen should not be overly bright or childish.
