Dynamic Medical Services, which provides medical and chiropractic treatment, is accused by the Equal Employment Opportunity Commission of having compelled at least four of its employees to participate in Scientology religious practices, and of having fired two for their refusal.

The company, in a statement faxed to ABC News, says it prides itself on the diversity of its staff and that it denies that it engaged in any improper or unlawful actions with regard to its employees. It intends, it says, to vigorously defend itself against the government's "baseless allegations" and expects to be vindicated.

The Church of Scientology did not respond to requests for comment by ABC News.

According to the EEOC's complaint, filed May 8, Dynamic Medical, owned by Dr. Dennis Nobbe, violated federal law by requiring employees named in the suit to spend at least half their work days in courses that involved "Scientology religious practices, such as screaming at ashtrays or staring at someone for eight hours without moving."
