Being a couple of design professionals, remote from the island, it was important that we trust the team. Quality, artistry, and stewardship of resources were our priorities. We experienced skill and care beyond our expectations and a bonus: we made friends for life.
South Mountain demonstrates deep attachment to the Vineyard’s values: collaboration, transparency, and respect for their surroundings. Their work shows that teams who have aligned around core values can produce exceptional work.
