Lester Park is well known around Minnesota for its spectacular beauty and rich history as a golf course because a unique view of Lake Superior is available on 20 of the 27 golf holes.

Golf course superintendent: A golf course superintendent is a person who professionally manages the labor, time, materials and financial resources needed to care for the turfgrass and landscaped grounds on a golf course.

Golf course superintendents communicate the status of the grounds and maintenance resources to members of the club’s management, owners or board of directors, green chairs and committees, golfers, vendors, suppliers, golf professionals, golf course architects and others in the golf industry.  Their management strategies must also align with the golf club business’ environmental and philanthropic role in the community.
