Silvio is an unusual talent. He is quite adept at combining his deep sense of strategy with an understanding of modern communications tools and technologies. He's also easy to work with - he will meet your budget and exceed your expectations. We had a tricky timeline and had to do a lot of juggling to make our production schedule work; Silvio adjusted on the fly and kept his cool through the whole process.

Marcacci Communications is a professional organization that delivers quality material on-time and on-budget. Whether it was redesigning our website or creating our open house materials, Marcacci Communications came through in the clutch. I would highly recommend them, and we look forward to working with Silvio and his team on future projects.
