A director of Tustin-based Quality Systems Inc. resigned Tuesday, citing sharp disagreements with the company's founder and chief executive.
The resignation of Don Cook, who was appointed to the board of directors in September, comes as Sheldon Razin, the founder, president, chairman and chief executive of the health-care information systems developer, has publicly fought with large shareholders over the company's direction and performance.
Several investors have urged Razin, who founded the company in 1974 and, with his wife, Janet, is the largest shareholder of the firm, to loosen his grip and allow more outsiders to guide decisions.
Razin "has done a lot to build this company over the years, but lately a lot of the decisions have not been very good and the performance has not been good," said Cook, a consultant on health-care information systems. "But it's a public company and it should be run like one."
