An incurable (I thought then) FUNGUS attacked both of my large toes nails in Junes of 1968; I was in Vietnam. Over the years I took both oral and topical medications, to no avail. The fungus remaind until I visited Dr. Spier in August 2011 for my first laser treatment. To date both of my large toe nails are growing in clear and normal. Thank you Dr. Spier for the outstanding work. The laser treatments work very effectively.
