She started out borrowing money from her fellow teachers, but police say she quickly graduated to stealing.
"She took $5,000 from the bank from another teacher's account," Doylestown Police Chie Chief James Donnelly said.
Police say Trymbiski took another teacher's drivers license and a bank deposit slip from her purse.
They say they have video of her at this bank drive-in window asking for large bills.
She got $5,000 from the other teacher's account.
And it doesn't stop there.
Police say Trymbiski has admitted stealing money from another teacher's pocketbook and even stealing money she collected from her own students for a teaching aid.
"There was money taken from pocketbooks, there was money taken from activities, she raised money for the children for reading books, things like that, they were never paid; she just kept the money," Donnelly said.
Action News tried to contact Trymbiski at the home she shares with her husband and three children.
Her lawyer says after she was confronted by the police, she entered a treatment program for a mental health issue.
The school principal alerted the police to the thefts last December.
But the Central Bucks School District says it only learned of the issue when contacted by Action News yesterday.
It's not clear if Trymbiski will be back in the classroom this fall.
Her lawyer says she will make full restitution.
