Monday marks the last day of John P. O’Connor’s illustrious career as reporter, editor and publishing executive at McKnight’s and we would be remiss if we all didn’t make appropriate hullabaloo over his retirement. Phooey on Irish good-byes. One of the most iconic runs ever by a business-to-business media editor is coming to an end. There is simply no journalist who has impacted the fields of skilled nursing, senior living and home care to the degree John O’Connor has during the last four decades.
