And I will continue to try to hire him back wherever I go." and "To call Tim a Web Developer is putting him in too general of a category and doing him a disservice. He's a specialist. I had the pleasure of having Tim on my team for two years and I'd like to think we produced some fine work together.

I look forward to working with him again."
