Thunder Bay's Health Sciences Centre continues to work towards filling the roles of two key executives who left the facility recently. CEO Andree Robichaud says they hope to fill Scott Pott's corporate services position by the fall. The job posting closes on Friday and interviews are expected to take place shortly after. Robichaud adds that Lori Marshall's previous job has been brought under the umbrella of another hospital department and a new position is being created to deal with communications and aboriginal affairs.
