Thank you for your submission. I would like to see what else you can come up with other than the prototypical medical cross. We do various Outpatient Surgical Procedures including outpatient Spine Surgery. Would you please let me know your idea(s) including a Spine. Also, it is not necessary to include all 4 colors. I chose White, Green, Purple and Blue for the meaning behind these colors. Any of them would be fine, but Green clashes with Purple...
