Wow! Very nice. Thank you for so many variations. I particularly like #28 & #30. I would very much like to see a wordmark submission from you. Also, let me know if you have any other color combination recommendations.
As I said in my first post, I like your submissions. I moved #25 to "not interested" because it was so similar to #26, but with less color. I don't like #28 as much now. It has a nice "look", but the image is a bit confusing to me and it reminds me of another logo I've seen somewhere, I think a local medical practice.
