Islanders will continue to see more integration of the Massachusetts General Brigham (MGB) brand at Martha's Vineyard Hospital, but Denise Schepici, CEO and president of the Island hospital, told The Times patient care won't change. Schepici said the brand changes have been slowly implemented over the past two years at the hospital, but signs outside the building aren't likely to be adjusted until sometime in the spring because they must go through the local planning process.
