I've been a writer for 35 years, and worked in journalism, the movies, academia, and the corporate world, and I've never met anyone quite like Jill.  As an advocate, she seems to have a perfect understanding of what you do, the clients who will appreciate it, and how you should work with them—which means you get the work, make money, and the jobs go smoothly.  That would be enough, as they say—but Jill is also a unique human being: sensitive to your creative nature without indulging you, straightforward in her opinions and advice without being harsh.  And she closes the deal.  You can't do better than Jill Cohen.
