Can a non-physician own a med spa in West Virginia?

Short answer
The cited rules do not settle this — they establish only that a corporation may not practice medicine without a board certificate of authorization, issued only where every shareholder is licensed under the medical, PA, or osteopathic articles.

West Virginia does not leave the corporate practice question to a general corporations statute — the Medical Practice Act itself makes it UNLAWFUL for any corporation to practice or offer to practice medicine, surgery or podiatric medicine, or to perform medical acts through one or more physician assistants, without a certificate of authorization issued by the Board of Medicine designating it an authorized medical corporation. To obtain one, an in-state applicant must furnish satisfactory proof that each shareholder is a licensed physician under the Medical Practice Act article or under the two other articles the provision cross-references by citation. For a corporation formed outside the state, the claim on record here is the shareholder test: it may be designated a foreign medical corporation on furnishing proof that ALL its shareholders are licensed physicians, podiatric physicians or physician assistants in one or more states, with a complete list submitted. The section’s other conditions for foreign corporations are not surveyed by these claims.
