Doctor of Naturopathic Medicine (ND or in Arizona "Naturopathic Medical Doctor" or NMD), in 16 U.S. states and six Canadian provinces refers exclusively to a medical degree granted by an accredited naturopathic medical school. While these degrees may be held by people outside of these states and provinces, in most other jurisdictions, the terms are unprotected and may be used by anyone, regardless of educational level. Practitioners who hold such a degree may also legally use the title 'doctor' in certain jurisdictions, but not in others. Equivalent professional titles may be reserved for ND/NMDs in other jurisdictions (Naturopathic Doctor, Naturopathic Physician, Naturopath), or there may be no legally protected title. This article discusses the accredited North American degree.

Those holding the accredited North America degrees generally practice as primary care providers of naturopathic medicine. Naturopathic medicine employs complementary and alternative medical therapies within the context of mainstream medicine, which claim to help improve the body's intrinsic ability to heal and maintain itself. Practitioners of naturopathic medicine prefer to use natural remedies such as botanical tinctures/medicinal herbs and foods rather than synthetic drugs. Naturopathic medical practice includes many different modalities. Practitioners emphasize a holistic approach to patient care, and may recommend that patients use conventional medicine alongside their treatments.

Simon Barker (born 4 November 1964) is an English former footballer. A blond haired, tough tackling midfielder, he scored 70 goals in 529 league appearances throughout a 17 year career in the Football League. He also represented England under-21's four times.

He began his career at Blackburn Rovers in 1983, winning the Full Members Cup with the club in 1987, before moving on to Queens Park Rangers the following year for £400,000. He played 351 league and cup games for QPR, before moving on to Port Vale in 1988. He retired in 2000.

Barker began his career at Blackburn Rovers under Bobby Saxton's stewardship in 1983. Rovers finished sixth in the Second Division in 1983–84, three places and 13 points outside of the promotion zone. They moved up to fifth in 1984–85, just two places and one point behind promoted Manchester City. Blackburn then dropped down to 19th in 1985–86, just one place and three points above relegated Carlisle United. New manager Don Mackay then rallied them to a 12th place finish in 1986–87. Barker played for Rovers in the 1987 Full Members Cup Final at Wembley, where Colin Hendry's goal was enough to beat Charlton Athletic 1–0. Blackburn reached the play-offs in 1987–88, but were defeated at the semi-final stage by top-flight Chelsea.
