Know-How Exchange : Taglines/Names

The non-profit organization I work for has always used the tagline “The Israel Health Support Organization Since 1979.” I, as a copywriter, would like to change that to “Helping People Face Their Challenges.” We are a humanitarian organization that offers a diverse array of medical and social services, and I feel that my new tagline captures the human side of what we do, while the old one sounds stuffy and vague.

A colleague of mine who raises funds abroad has objected vehemently to my suggested change. These were her comments:

 If we are changing our line to "Helping People Face Their Challenges": Why? And where are we helping them? The original line told a lot in a few words.
 One of the most common faults in a tagline is "lack of focus". I fear that the new line is too general, and subject to each individual's interpretation.
 Please don't drop the fact that we have been around since ''79 or for 25 years. This adds significantly to our credibility.
 For fundraising and PR abroad, it is critical to emphasize that we operate in Israel.

I put this to you, the experts, to decide: Will it stay “The Israel Health Support Organization Since 1979,” or should we opt for “Helping People Face Their Challenges”? Or perhaps something else entirely?

Thanks,
Molly
