Fit Family ChiropracticLogo Design Contest

Fit Family Chiropractic provides natural health care with a hint of fitness.

Primarily
Green - vibrant, health, life, growth (different shades possible)
Any other color if necessary and used creatively and tastefully.

Interior design of the office is modern/industrial painted shades of black and grey with splashes of vibrant green.
We are open to anything so please be creative but want to share ideas that we like...the tree seems to be a great symbol for life and vitality. We like the watermark style people maybe 3-4 (family) to show elements of "fit" without being too overpowering. We like things like the watermarked family be shaped like a tree, or have green leaves coming from them as a symbol exuding life. Must have the words "Fit Family Chiropractic". Displayed however is suitable, in any font, different fonts, whatever.
I think bright green on a black background looks cool.
Does not need to have a spine anywhere visible in the logo, but may if used nicely.
