The former office manager of a Boston-based dental practice pleaded guilty to charges of bank fraud and tax fraud stemming from her embezzlement of funds from her former employer. Yuliya Vaysglus, a/k/a Julia Vaysglus, 36, formerly of Hopkinton, now residing in Campbell, Calif., pleaded guilty to eight counts of bank fraud, one count of aggravated identity theft and three counts of filing false tax returns. From 2009 until she was terminated in February 2015, Vaysglus was the office manager of a Boston-area dental practice where her duties included tracking client invoices, depositing insurance payments into the practice’s bank account, and recording those deposits for accounting purposes. Between 2009 and December 2014, Vaysglus embezzled more than $348,000 from the dental practice by diverting to herself at least 276 checks from various insurance companies for services rendered to patients. As part of the scheme, Vaysglus made the checks payable to herself, forged the signature of the dental firm’s owner on the checks, and deposited them into her bank account. Vaysglus failed to report the embezzled funds on her federal tax returns.
