The company filed the Form D on March 6. It did not disclose what it intended to do with the proceeds.

The center has over 50 board certified physicians and is lead by executive officers Bill Hubbard, Francis Langford, David Rhodes, Robert Bashore and William Goglin.

Companies relying on a Reg D exemption do not have to register their offering of securities with the SEC, but they must file what’s known as a Form D electronically with the SEC after they first sell their securities.
