Two fake medical professionals have been convicted in separate trials in Brooklyn and Queens this month, the state attorney general’s office said Friday.

Both phonies were practicing despite having no license, AG Eric Schneiderman said.

In one case, Alexander Hollander, 70, was a former dentist who lost his license to practice after a June 2000 Medicaid fraud conviction, the AG said.

Hollander still owed $140,000 restitution from that fraud. When Medicaid officials went looking for him, they caught him at his 7th Avenue Dental Office in Sunset Park.

Hollander handed his business card to a Medicaid undercover investigator — “Doctor of Dental Surgery,” it read.

In an unrelated case, the other fake, Noucheline Jean, 45, lied that she was a licensed practical nurse and spent 18 months treating patients at the Park Nursing Home in Rockaway Park, the AG said.

Hollander and Jean have August sentencing dates.
