Bonita Man Pleads Guilty To Posing As Doctor

Kurt Donsbach, 75, Faces Up To Year In Jail

A Bonita man who posed as a doctor and offered patients dangerous dietary supplements as alternative remedies for cancer, arthritis and other ailments pleaded guilty Monday to 13 felony charges, including practicing medicine without a license and selling misbranded drugs.

Kurt Walter Donsbach, 75, faces up to a year in jail, followed by probation, when he is sentenced March 4 by Judge Charles Rogers. Had he been convicted at trial instead of reaching a plea deal, Donsbach would have faced a maximum of 13 years in prison.

Even though he has no medical license in California, Donsbach hosted a radio show on the Internet -- "" -- where he represented himself as a chiropractor and naturopathic doctor, authorities said.

Donsbach offered "alternative, natural and nutritional" remedies for conditions such as cancer and auto-immune disorders, according to authorities.

One woman injected herself with "neuropeptides" to treat arthritis after Donsbach told her it would "re-program" her body's T-cells. The patient paid thousands of dollars for the drugs and injected herself monthly for six years, causing severe bone density loss, said Deputy District Attorney Gina Darvas.

In another case, Donsbach claimed he had treated pancreatic cancer successfully about 60 percent of the time and provided a supplement with nimesulide to a patient, authorities said.

Nimesulide, a non-steroidal anti-inflammatory, is not approved by the Federal Drug Administration for use in the United States, Darvas said.
