Three Rings Inc. has brought on Andy Murphy as a principal. Murphy was a co-founder of Davies Murphy Group, which was acquired by LEWIS Global Communications in 2013. At Three Rings, he will re-unite with fellow principals Lisa Paglia and Doug Broad, who worked with him at DMG and later LEWIS for more than 15 years. “Lisa and Doug started Three Rings one year ago and have done a spectacular job,” Murphy said. “My goal is to bring another creative dimension to the team and drive the Three Rings value proposition even deeper into the high-tech market.” Three Rings has also moved into new offices at 399 Boylston Street in Boston.
