Plenty of entrepreneurs like to think of their business as one of a kind, but for Dr. Heather Nelson it might actually be true. Heather owns Heather Nelson Studio in Springfield, Mo. Heather’s unique musical training certainly qualifies her as a piano and vocal teacher, but she primarily works with those suffering from vocal injuries. While her typical clients range from novices to professional vocalists, Heather also provides vocal regimens and techniques to those who have damaged their vocal cords or been diagnosed with nodes or polyps to help them sing again.
