O'Leary-led cost-cutting aids financial turnaround at AMI.

Wall Street analysts are giving Robert O'Leary good grades for his first year as chief executive at American Medical International. Mr. O'Leary, who joined the Dallas-based hospital chain in July 1991, has spent the past year and a half recruiting his own team of senior executives and implementing a new agenda for the company. But it's his aggressive cost-cutting and the bottom-line improvements that have earned him the highest marks.
