One more way that Hercules is different from other companies is in how strongly we encourage you to “stay in touch,” and by making it easy for you to do so. We constantly welcome feedback, questions, ideas, suggestions, comments – anything you’d like to share! Here are some of our staff members with whom you may want to get in touch. Yes, we are providing their e-mail addresses and their phone extensions! -- even for our President and CEO, David Siegal. At Hercules, we don’t shy away from our customers. In fact, we look forward to getting to know you better.
