Samuel K. Tennis was recommended by a colleague as 'the best in the business' on devising and revising indicators for Omega Research programs. I contacted Sam Tennis with an emergency matter (or at least I deemed it an emergency). Although I reached him during the weekend, he could not have been more responsive or professional. Sam completed the job in a matter of hours, not days, and continued to revise as needed in a consistently congenial, upbeat manner. What a pleasure!!! The man is an artist of his trade. I recommend his services in the strongest terms and am now a long-term customer.
