Chad Brian Litz got quite a surprise when he hopped off a cruise ship in Tampa, Florida earlier this month: Police officers were waiting for his arrival, eager to arrest him after officials say it was revealed that the medically-untrained Litz had successfully scammed his way into a nurse practitioner position at a San Francisco health clinic for a four month period.

According to a press release sent by the San Francsico District Attorney's office, the 39-year-old Daly City resident had volunteered at the San Francisco City Impact health clinic at 232 Jones Street for four months, where he treated "at least 28 different patients...with little supervision, including prescribing privileges that enabled him to dispense controlled substances to patients." But according to the DA's office, Litz "has no apparent medical training or experience," and used "a forged certificate from the American Academy of Nurse Practitioners as well as other fraudulent materials" to obtain the gig.

Litz, who the DA's office says "has never been licensed to practice as a nurse or doctor" but worked at the clinic for four months, from when the clinic from December 2013 through April 2014, the Chron reports.

According to its website, the San Francisco City Impact Health and Wellness Center

...is under the umbrella of San Francisco City Impact Rescue Mission, serving 47,000 residents of the Tenderloin District of San Francisco with a hot meals, spiritual and practical encouragement through volunteers, social workers and staff. City Impact also operates City Academy, a private elementary through high school attended by over 100 students from low income families as well as the home of the Adopt a Building program. Adopt a Building brings hope to the poor through positive personal relationships fostered by the program.

We offer an Urgent Care, 9 Specialists, Community Health Education, Patient Advocacy and a unique "Total Wellness Program." We are working towards becoming the ‘medical home’ for low income residents in the Tenderloin that fall 250% below the federal description of the poverty line. We are a place where a patient can receive a free screening and treatment, discuss and set health goals that encompasses the body, mind and spirit. Our treatment philosophy is similar to that of family medicine by taking into account a patient's total living environment, proactively seeking improvement through health education, lifestyle changes, and the availability of new positive relational experiences.

"All clinic services are provided by volunteers, free-of-charge for [sic] serviced provided by our clinic," they say on their site., which says the organization was launched thusly:

One early morning in 1984 after getting off the graveyard shift, Roger Huang was waiting for a tow truck in the Tenderloin. He noticed a young boy being picked on by a group of bullies. Torn between intervening to help the boy and not wanting to get involved, he drove away with a heavy heart. On the way home God laid the burden on his heart, “What if that was your son being picked on?” The next morning Roger and Maite made 50 sandwiches, and Roger went back to the Tenderloin to give them away to the homeless that same day. The following week he brought his wife Maite to the Tenderloin to help with the ministry, and San Francisco City Impact was born.

In a written statement regarding the case, San Francisco City Impact says:

Chad Litz was a volunteer (not an employee) in December 2013 as we were just getting started as a clinic and were pursuing a license. Shortly after he started volunteering, USF nursing school notified us that he had a criminal background and we appropriately responded and alerted authorities. We were contacted by the department of consumers affairs and went through a thorough investigation, reviewing all documentation and patients he saw. We did everything to ensure that our patients were safe and that the care did not cause any harmful outcomes.

As part of credentialing, we collect resume IDs and any relevant licenses. He produced said licenses and an NPI number, which turned out to be fraudulent. Our clinic’s scope of practice was very limited at the time because of it’s infancy. Nonetheless, all patients and visits were reported to the Department of consumer affairs during thorough investigation.

According to ABC 7, "Litz was sentenced to four years in prison for identity theft in 2011. He was released in March of 2013." He was cited by the California Board of Registered Nursing in 2015 for "unlawful practice and being a nurse imposter."

According to ABC 7, Litz's "LinkedIn page lists extensive credentials including two master's degrees" and claims he also worked at Opera Plaza Dentistry. As of Friday morning, the profile, nicknamed "nursechad," appears to be deleted.

SF Weekly also points us to this Twitter account they say might be his, which "discloses that he may have been on a Holland America Line, where he claims he was overcharged by the spa services on board."

"Tourism and Medicine , that's mostly my life," the bio on the account, monikered @ChadLitz, reads.

It was the former pursuit that the suspect appeared to be enjoying when he was arrested on March 10 as he stepped off the boat "on a warrant alleging four felony counts for practicing medicine without a license and one felony count for identity theft," the DA's office says.

But for now, his traveling days are over, as he remains in custody with bail set at $65,000. According to the DA's office, Litz was arraigned Thursday and pled not guilty, and will return to court on April 11 at 9 a.m. for a preliminary hearing.

Meanwhile, the DA's office asks that anyone who believes they've been treated by Litz contact investigator Andrea Todd at San Francisco's Department of Consumer Affairs. She can be reached at 510-888-7072.
